How does organic farming help to conserve ecosystems?

Organic agriculture is based on practices that not only protect environmental health, but also strive to improve it. Instead of relying on synthetic pesticides and fertilizers that can deplete the soil of valuable nutrients and increase environmental degradation, organic agriculture builds up soil using such practices as composting, cover cropping, and crop rotation.

Is organic agriculture bad for the environment?

There is an even more stark difference, however, between beliefs about the effects of organic farming on the environment and reality. In fact organic farming is worse for the environment than conventional farming in terms of the impact vs the amount of food produced. First, organic farming may use pesticides.

Why is farming environmentally conscious?

Environmentally-conscious farming improves both our bodies and our physical surroundings. People are sickened by the thought of pesticides and want to eat foods that are free of their chemical taint. Wholesome, nutritious food is profitable. Organic farmers receive a much higher return on their crops than traditional ones.

Why is organic farming important?

Organic farming greatly mitigates this problem. Because organic farms often have better soil quality, the method also conserves water. Popular crops like cotton require a lot of water to thrive. Organic cotton farms, however, require less irrigation. That means they need to use less water.

How would the environment benefit from organic farming?

The environment would benefit if more farmers adopted organic methods. The harsh chemicals used by traditional growers are harmful to the environment and for the animals living in the area. Organic farming alleviates or reduces the negative environmental consequences associated with conventional agriculture.

How do organic farmers work?

Organic farmers, by contrast, pump the soil full of organic matter. Chemicals tend to kill off a lot of the bacteria in the ground. Farming can be quite expensive too.

How does organic farming help the soil?

Organic farming can help improve soil quality in a myriad of ways. In particular, it can help battle erosion. Scientists comparing organic wheat fields with their traditionally grown cousins found that the organic field was covered with over eight inches more topsoil.

Why did the Gulf of Mexico dead zone form?

geological study discovered that the Gulf of Mexico dead zone, an area with too much nitrogen to support life, was formed in response to chemical fertilizer runoff from farms. At its largest, the Gulf of Mexico dead zone has more surface area than some U.S. states.

What happens when a farmer takes over a virgin field and pumps it full of synthetic fertilizers?

When a farmer takes over a virgin field and pumps it full of synthetic fertilizers, the soil will lose almost 65 percent of its nitrogen content over the next five decades . When that happens, the farmer will be stuck using more and more fertilizer to achieve the same results.

How do organic farmers control pests?

Instead, they aim to control pests through more natural methods like cover crops, composting and crop rotation. 2. Maintains a Healthy Soil. As previously stated, pesticides and chemicals contaminate the soil.

How do algal blooms affect the environment?

Often, they occur when runoff from farms carry chemicals and fertilizers. They grow out of control and are difficult to get rid of. In addition to harming the environment, they damage the economy.

How does erosion affect the soil?

Erosion affects more than just the soil. When soil is swept away, the land is affected, and human food sources decrease. Further, organic farmers limit tillage on fields, keeping dirt from eroding because the soil isn’t broken up so often. 4. Provides Cleaner Water.

Why is it important to grow organically?

A lack of clean water is a real danger. Organic farming helps keep the water supply safe and clean because it doesn’t use harmful chemicals. One of the primary sources of water pollution comes from agricultural soils when water runs off into rivers and streams.

How to maintain healthy soil?

One of the primary ways they maintain healthy soil is by using compost, which contains many helpful bacteria that build up the ground. 3. Reduces Erosion.

What do you see when you go to the produce section at a store?

When you go to the produce section at a store, you see signs for organic products. They tend to be more expensive than non-organic, but they look similar.

Why are there no pests?

Humans labeled certain insects, animals or invasive plants as pests because they hinder the amount of food produced or are a general nuisance to humans. To manage pests, humans have created pesticides, which have harmful effects on the environment.

Why is it important to increase organic yields?

Increasing yields in organic systems would help address the contrasting findings between per area and per unit of product results, but the push to increase yields could also erode some of the benefits. Soil nutrient deficiencies were cited as a major cause of reduced yields, something that can be addressed through better use of the range of organic residuals available. The authors noted that in experiment station trials with high soil fertility, yields were more comparable between the two systems. Yields were also often reduced by inadequate control of weeds, insect pests, and diseases. Thus, there is clearly opportunity for research and education to help improve organic crop yields, which will lessen the environmental impact per unit of product and address the question of the increased land area needed for organic systems to produce the same food output as conventional. Yields do matter, and better data on yields from a large number of organic farms would help improve our understanding of this issue.

What is the organic yield of potato?

For potato, organic yields ranged from 11-132% of conventional, with a mean of 68%. For spring wheat, the range was only 70-87% of conventional, with a mean of 78%. So while environmental benefits are evident in organic systems, lower yields remain a factor to consider, especially when looking at land use. In this study, the lower yields and crop …

Is soil organic matter higher on organic farms?

Tuomisto and colleagues found that soil organic matter was an average of 7% greater on organic farms, mostly due to higher inputs (+65%) of organic materials, often manure. Nitrate leaching was 31% lower per unit area with organic, but 49% higher per unit of product.

Is organic farming good for the environment?

While most consumers may choose organic foods for their potential health characteristics (e.g., lower chance of pesticide residue and potentially greater nutrient value), these same consumers generally believe that organic farming is “good” for the environment and thus worth supporting.

How does organic agriculture reduce water pollution?

As the use of these is prohibited in organic agriculture, they are replaced by organic fertilizers (e.g. compost, animal manure, green manure) and through the use of greater biodiversity (in terms of species cultivated and permanent vegetation), enhancing soil structure and water infiltration. Well managed organic systems with better nutrient retentive abilities, greatly reduce the risk of groundwater pollution. In some areas where pollution is a real problem, conversion to organic agriculture is highly encouraged as a restorative measure (e.g. by the Governments of France and Germany).

How does organic farming affect biodiversity?

At the gene level, traditional and adapted seeds and breeds are preferred for their greater resistance to diseases and their resilience to climatic stress. At the species level, diverse combinations of plants and animals optimize nutrient and energy cycling for agricultural production. At the ecosystem level, the maintenance of natural areas within and around organic fields and absence of chemical inputs create suitable habitats for wildlife. The frequent use of under-utilized species (often as rotation crops to build soil fertility) reduces erosion of agro-biodiversity, creating a healthier gene pool – the basis for future adaptation. The provision of structures providing food and shelter, and the lack of pesticide use, attract new or re-colonizing species to the organic area (both permanent and migratory), including wild flora and fauna (e.g. birds) and organisms beneficial to the organic system such as pollinators and pest predators. The number of studies on organic farming and biodiversity increased significantly within the last years. A recent study reporting on a meta-analysis of 766 scientific papersconcluded that organic farming produces more biodiversity than other farming systems.

How does organic farming help the environment?

Air and climate change. Organic agriculture reduces non-renewable energy use by decreasing agrochemical needs (these require high quantities of fossil fuel to be produced). Organic agriculture contributes to mitigating the greenhouse effect and global warming through its ability to sequester carbon in the soil. Many management practices used by organic agriculture (e.g. minimum tillage, returning crop residues to the soil, the use of cover crops and rotations, and the greater integration of nitrogen-fixing legumes), increase the return of carbon to the soil, raising productivity and favouring carbon storage. A number of studies revealed that soil organic carbon contents under organic farming are considerably higher. The more organic carbon is retained in the soil, the more the mitigation potential of agriculture against climate change is higher. However, there is much research needed in this field, yet. There is a lack of data on soil organic carbon for developing countries, with no farm system comparison data from Africa and Latin America, and only limited data on soil organic carbon stocks, which is crucial for determining carbon sequestration rates for farming practices.

What is organic agriculture?

Sustainability over the long term. Many changes observed in the environment are long term, occurring slowly over time. Organic agriculture consider s the medium- and long-term effect of agricultural interventions on the agro-ecosystem. It aims to produce food while establishing an ecological balance to prevent soil fertility or pest problems. Organic agriculture takes a proactive approach as opposed to treating problems after they emerge.

Is GMO organic?

Genetically modified organisms. The use of GMOs within organic systems is not permitted during any stage of organic food production, processing or handling. As the potential impact of GMOs to both the environment and health is not entirely understood, organic agriculture is taking the precautionary approach and choosing to encourage natural biodiversity. The organic label therefore provides an assurance that GMOs have not been used intentionally in the production and processing of the organic products. This is something which cannot be guaranteed in conventional products as labelling the presence of GMOs in food products has not yet come into force in most countries. However, with increasing GMO use in conventional agriculture and due to the method of transmission of GMOs in the environment (e.g. through pollen), organic agriculture will not be able to ensure that organic products are completely GMO free in the future. A detailed discussion on GMOs can be found in the FAO publication "Genetically Modified Organisms, Consumers, Food Safety and the Environment".

Why is organic farming bad?

Conventional farming has been heavily criticized for causing biodiversity loss, soil erosion, and increased water pollution due to the rampant usage of synthetic fertilizers and pesticides. However, despite these glaring cons, scientists are concerned that organic farming has far lower yields as compared to conventional farming, and so requires more land to meet demand.

Why is it true that we had a small comparison between organic and conventional farming based on Swedish statistics?

This is because Sweden is one of the very few countries that has statistics that include the yields from organic and conventional crops.”

What is sustainable agriculture?

Sustainable agriculture involves the use of nature’s goods and services while maintaining them for future generations ( Altieri, 1995, Thrupp, 1996, Pretty et al., 2003, Pretty, 2005, Pretty and Hine, 2001, Tilman et al., 2002 ). Organic agriculture is considered to be one of the production systems that aim to achieve sustainability ( Reganold et al., 1990, Lampkin and Measures, 2001, Mäder et al., 2002) by utilising and maintaining ES. The estimated magnitude (scale 1–5; in the ratings, 1, 3, and 5 represent the lowest, medium, and highest levels of ES, respectively) of several ES is very high in organic agriculture compared with high-input substitution agriculture ( Takatsuka et al., 2009, Sandhu et al., 2005 ). It is well established that organic farming delivers more environmental benefits than does conventional agriculture. The economic value of ES in New Zealand organic fields was found to be $1516 ha ?1 yr ?1 as compared to $670 ha ?1 yr ?1 in conventional ones ( Sandhu et al., 2008 ). These values comprised reduced variable (labour, fuel, pesticides) and lower external costs to human health and the environment.

What are the services of an ecosystem?

Ecosystem services (ES), such as biological control, pollination, soil formation, nutrient cycling in agriculture are vital for the sustainable supply of food and fibre. The current trends of decline in the ability of agricultural ecosystems to provide ES pose great threat to food security worldwide. This paper discusses the concept of ES and identifies ES associated with agriculture. It discusses the economic and ecological benefits of these ES on farmland in general and its linkages with organic agriculture. The provision of ES on farmland may help to motivate the redesign of small-scale farms using new eco-technologies based on novel and sound ecological knowledge. This has potential to meet the food demand of growing population without damaging human health and the environment.

What are the services that are required to support the production of other ecosystem goods and services?

In this case they support the production of grain, wool, fruit and vegetables, etc. Key supporting ES associated with agriculture are biological control of pests (natural enemies of insect pests control the pest populations), biological control of diseases and weeds (natural suppression by soil microbes of soil-borne diseases and weed seed removal by predators), pollination (for seed production), nutrient supply (availability of nutrients by soil microbial activity), carbon sequestration (storage of carbon in soils and vegetation), soil formation (soil turnover by earthworms) etc. The global economic value of these ES was estimated to be $100, $80, $100, $90, $135 and $25 billion annually, respectively ( Pimentel et al., 1997 ).

Is organic farming sustainable?

Organic agriculture both utilises and maintains ES. It is therefore more sustainable than is conventional agriculture which degrades some ES. Apart from providing ES, organic agriculture is capable of contributing significantly to global food supply. One recent study ( Badgley et al., 2006 ), examined 293 cases from all over the world and compared yields of organic and conventional systems. This study ( Badgley et al., 2006) indicated that organic agriculture has potential to contribute significantly to the global food supply. Increasing concerns about food security in least developed and developing countries will require a wide range of sustainable agricultural practices (combining some organic and conventional practices) to fulfill the food demand of a growing population ( Ericksen et al., 2009 ). Organic agriculture offers great potential to develop low cost, low input, locally available eco-technologies (as discussed in Section 3.2) to produce food and fibre ( Badgley et al., 2006 ), without causing damage to human health and the environment ( UN, 2008 ). This type of ecological knowledge can be easily transferred to small-scale farms in least developed and developing countries where the need is much higher due to non-availability of other high-input and costly resources.

Is agriculture a consumer or producer?

Agriculture is both a consumer and a producer of ES ( Fig. 1) ( Heal and Small, 2002, Sandhu et al., 2005, Takatsuka et al., 2009 ). A number of ES are utilised to produce other ES such as food, which is supported by the maintenance of soil fertility, plant protection, water regulation and many other services ( Daily et al., 1997, Pimentel et al., 1997 ). By using the concept of ES, researchers and practitioners aspire to strike a balance between production and consumption of ES in agriculture for long-term farm sustainability ( Bjorklund et al., 1999, Firbank, 2005 ).

What are the four cropping systems?

The researchers used a six-year dataset from the Farming System and Tillage (FAST) experiment and compared the agronomical, ecological and economic impacts of four arable cropping systems — conventional intensive tillage, conventional no tillage, organic intensive tillage and organic reduced tillage.

How does organic farming affect the environment?

Organic farming also had a reduced environmental impact, with a 46-51 per cent lower global warming potential and an 80-85 per cent reduced aquatic ecotoxicity potential per hectare, the report said.

What are the three pillars of conservation agriculture?

Conventional no tillage and organic reduced tillage systems are considered to reflect conservation agriculture, as the three pillars of conservation agriculture — minimum tillage, six-year crop rotation and permanent soil cover with crop residues and cover crops — are largely fulfilled.

How many goods and services were used in the study for multifunctionality assessments?

Nine agroecosystem goods and services were used in the study for multifunctionality assessments: Biodiversity conservation, soil conservation, erosion control, water and air pollution control, food production, income, work efficiency, and financial independence.

How does intensive tillage improve performance?

Conventional systems with intensive tillage showed improved performance and it can be explained by way of increased weed control and a better availability of applied nutrients.

What are the differences between conventional and organic farming?

The use of mineral fertilisers and herbicides in conventional systems led to higher yields for wheat and maize compared to organic systems. The differences between conventional and organic systems were less pronounced for legume crops like field beans and grass-clover ley.

What are the services that an agricultural system provides?

An agricultural system should be able to provide the desired balance of services — food production, regulation services (soil, water and climate protection), supporting services (biodiversity and soil quality conservation) as well as providing for an ensured income and suitable working conditions.

Which is good organic farming or natural farming?

Organic farming and the areas with restrictions/limitations or natural obstacles for agriculture. Organic farming, due to its production characteristics, can be a good choice for farming in areas such as “areas facing natural or other specific constraints” (ANCs), before in the EU called “less favored areas” (LFAs), protected areas (national, regional, or landscape parks), Natura 2000 areas, and water protection areas.

How to control weeds in organic farming?

Weeds are the most problematic components in organic cultivation, as these spread unnecessary growth by taking all the nutrients from the organic soil and also create diseases, shelter to the insects, etc. The weeding procedures should be done rapidly for the success of Organic Vegetable Farming. Weeds can be reduced by following many ways such as Biological. Cultural, thermal and Mechanical schemes. But following these methods incurs a lot of work and is costlier. Cultural Weed control process is the most common method followed in Organic Vegetable Farming. These cover crops surpluses the soil which stops weeds growth. Intercropping can also be the best solution. Biological weed control procedures such as Nitrogen eradicates and using irrigation also helps to lessen the growth of weeds by reducing the moisture content to the weeds. Organic wedding tools such as Brush weeders, Summers, Mowers, Hoes, Tines, Harrows are used in weeding.

What is organic vegetable farming?

Organic vegetable farming excludes synthetic inputs such as Chemical Fertilizers, pesticides, hormones, feed additives, etc. to the maximum extent. This helps the soil to retain its nutrients.

What are the components of organic farming?

Manures, Green sand, Sulfur, Potassium, Nitrogen, Phosphorous, Vermicompost, Biofertilizers, Boron, Bone meal, Green Manure Crops , etc. are the important components required for the Organic Vegetable. Most of the farmers rely on compost which is well decomposed as a natural fertilizer. Green manure helps to get the nitrogen from atmosphere along with which it increases soil nutrients and helps to store and hold the organic matter and nutrients in the non-growth season. Hence, the soil remains fertile for longer durations. This also helps to prevent diseases and insects. Animal Manure adds great advantages to the soil in turn for the field or land. Potash helps to increase the potassium content in soil. Weeds and unwanted plants take advantage to grow rapidly in this farming which harms the vegetable and crops.

Why is green manure good for soil?

Green manure helps to get the nitrogen from atmosphere along with which it increases soil nutrients and helps to store and hold the organic matter and nutrients in the non-growth season. Hence, the soil remains fertile for longer durations. This also helps to prevent diseases and insects.

How deep should a raised vegetable bed be?

Raised beds are more productive in Organic Vegetable Farming. Beds can be created in any shape by digging the soil 8-10 inches deep and raise the bed 4-6 inches up. This allows roots to grow faster at a depth of 12-16 inches. An important point to be noticed that bed depth depends upon vegetable varieties.

What is organic farming?

How does animal manure help soil?

Animal Manure adds great advantages to the soil in turn for the field or land. Potash helps to increase the potassium content in soil. Weeds and unwanted plants take advantage to grow rapidly in this farming which harms the vegetable and crops.

How to add organic matter to soil?

Since synthetic fertilizers are not used, building and maintaining a rich, living soil through the addition of organic matter is a priority for organic farmers. Organic matter can be applied through the application of manure, compost, and animal by-products, such as feather meal or blood meal. Due to the potential for harbouring human pathogens, the USDA National Organic Standards mandate that raw manure must be applied no later than 90 or 120 days before harvest, depending on whether the harvested part of the crop is in contact with the ground. Composted manure that has been turned 5 times in 15 days and reached temperatures between 55 and 77.2 °C (131 and 171 °F) has no restrictions on application times. Compost adds organic matter, providing a wide range of nutrients for plants, and adds beneficial microbes to the soil. Given that these nutrients are mostly in an unmineralized form that cannot be taken up by plants, soil microbes are needed to break down organic matter and transform nutrients into a bioavailable “mineralized” state. In comparison, synthetic fertilizers are already in mineralized form and can be taken up by plants directly.

How does organic pest control work?

In addition to pesticides, organic pest control integrates biological, cultural, and genetic controls to minimize pest damage. Biological control utilizes the natural enemies of pests, such as predatory insects (e.g., ladybugs) or parasitoids (e.g., certain wasps) to attack insect pests. Pest cycles can be disrupted with cultural controls, of which crop rotation is the most widely used. Finally, traditional plant breeding has produced numerous crop varieties that are resistant to specific pests. The use of such varieties and the planting of genetically diverse crops provide genetic control against pests and many plant diseases.

Why is organic farming important?

How does tilling help soil?

Soil is maintained by planting and then tilling in cover crops, which help protect the soil from erosion off-season and provide additional organic matter. The tilling in of nitrogen-fixing cover crops, such as clover or alfalfa, also adds nitrogen to the soil.

How to become certified organic?

Department of Agriculture (USDA) regulates the use of the term "organic." In order to become certified organic, a grower uses production and handling practices in accordance with the National Organic Program (NOP) and becomes certified by a USDA-accredited certifying agency. Growers whose gross income from organic production is $5,000 or less are exempt from this rule. In this case, production and handling practices in accordance with the NOP are still used and other restrictions regarding labeling and combination with other organic products apply. It takes a minimum of three years to transition from nonorganic production to certified organic production. During this period products cannot be labeled as organic and may not command the higher prices usually associated with organic products. Growing organic requires detailed recordkeeping and more management and planning time than other production systems.

How to improve soil fertility?

This is done by using sound crop rotations, green manures and cover crops, plant and animal matter, and fertilizers or soil amendments allowable according to the National List. Soil testing should be used to determine pH and levels of phosphorus, potassium, calcium, and magnesium. Penn State soil test kits are available through local extension offices or from the Agricultural Analytical Services Laboratory. Kits can also be obtained from other soil testing laboratories. The nutrient levels in the soil will indicate the amount of additional nutrients needed for optimal vegetable crop growth and development.

What is an organic system plan?

An Organic System Plan (OSP) is a thorough record describing the practices and procedures used on the farm to achieve and maintain the requirements of the NOP. An OSP is unique to a particular operation. Many certifying agencies have templates for developing an OSP, or you can develop your own. The National Sustainable Agriculture Information Service published a document containing a template including all the required information.

How to prevent pests and diseases?

For preventing pests and diseases other than enriching soil fertility, you must follow crop rotation. This is can be carried out after you harvest the vegetables in the garden, so they should be ready for sowing once again. As part of the crop rotation, you have to plant different vegetables in the same space.

How to stop weeds from eating veggies?

To stop this from occurring, you want to receive a bird, even a toad as well as other insects to consume them. For weeds, the one thing that you can do is pull these ones from a single from the floor. As for different creatures, setting up fences and utilizing animal hair, baby powder or deodorant soaps appears to be a great deterrent.

How does rowcover affect plant growth?

The impact of rowcovers on plant growth was significant. Use of rowcovers increased vine length, flower count, leaf area, leaf count, plant biomass, and total marketable yield. Use of compost in conjunction with rowcovers enhanced the rowcover effect.

Why do growers use compost?

Growers routinely use compost for nutrient provisioning and rowcovers for insect exclusion and growth enhancement. The objective of this work was to study the combined effect of rowcovers (with different light transmission) and compost organic cucumber (Cucumis sativus L.) growth and micro- climate.

How does organic farming improve vegetable quality?

Organic farming is commonly regarded as a system improving vegetable quality. The aim of work was to analyse the effects of the organic methods on the vegetable quality during its production and storage on the way to the consumer. Therefore the nutritive, sensory and storage quality of carrots and potatoes from organic farms has been compared to the crops quality from conventional farms. It was found that organic vegetables had lower yields, but most of their nutritive, sensory and storage quality attributes were better than in the conventional crops. It should be emphasised that lower level of nitrates and simultaneously higher content of vitamin C in organic potatoes can have an important anti-carcinogenic impact on human organism. Organic vegetables more readily comply with food requirements for infants and small babies and should be recommended for baby foods. Organic farming can be considered as a system providing good conditions to improve the vegetable quality. Nevertheless there are many possibilities to ameliorate the methods of cultivation and storage of organic crops to obtain better production and qualitative results.

What is organic gardening?

The words “organic” and “sustainable” are often used interchangeably to describe a holistic gardening approach that recognizes that soil health, plant health, ecosystem health, and human health are all interconnected. Organic and sustainable approaches are similar and complementary.

Why are gardens and landscapes not natural areas?

Gardens and landscapes are not natural areas. To create these outdoor spaces for our benefit we move and change the soil, alter water flow across the ground, and planting what pleases us. We disrupt the larger ecosystems made up of soil, water, air, plants, animals, and microorganisms that interact in the “web of life.” Ecosystem services are the benefits we get from a well-functioning ecosystem and include healthy food to eat, and clean water and air.
