how hydroponics is becoming boon in farming插图

Hydroponics is a like a blessing of modern technology to agriculture.It can grow the healthiest foodpossible,in large quantities,in the smallest space and in a sustainable way. Not only does hydroponics accomplish all the goals set by organic farming,but it takes a step further byoffering people the ability to grow food in places where traditional agriculture simply isn’t possible.

What are the benefits of hydroponic farming?

Growing crops in near optimal conditions using controlled environment agriculture (CEA) technology is one of the biggest benefits of hydroponic farming. Crops grown indoors and hydroponically can be grown anywhere on earth at any time of the year, regardless of weather conditions, availability of cultivable land, or soil quality.

What is hydroponics and how does it work?

What Is Hydroponics? Hydroponics is a type of agriculture or gardening method that doesn’t use soil. The term comes from the Greek words “hudor” for water and “ponos” for work, so in translation, it essentially means “water-working.”

Can hydroponic farming solve the world’s food shortage?

This is one of the reasons the UN’s Food and Agriculture Organization (FAO) is helping to implement the use of hydroponic farming in areas of food shortages to help produce more crops and feed more people. Plus, plants grown hydroponically can grow at least 20% faster than their soil-bound counterparts.

Is hydroponics the answer to growing food without soil?

Some researchers believe that hydroponics — a method of growing food with water, nutrients, and light, but no soil — could be part of the solution. But does it work?

Why is hydroponic farming important?

Hydroponic farming has strong potential to mitigate the threats these issues pose to our agricultural system. Growing crops in near optimal conditions using controlled environment agriculture (CEA) technology is one of the biggest benefits of hydroponic farming. Crops grown indoors and hydroponically can be grown anywhere on earth at any time of the year, regardless of weather conditions, availability of cultivable land, or soil quality. Hydroponic farming has the potential to provide fresh, local food for areas with extreme droughts and low soil quality, such as in sub-Saharan Africa where access to leafy green vegetables is often limited.

What is controlled environment farming?

Controlled environment agriculture (also known as weather and climate-proof farming, or more commonly indoor vertical farming), is the production of plants in an indoor environment. While indoor farming is not a new phenomenon (greenhouses have been used for centuries), the more recent innovation of hydroponic farming breaks down the growing process even further by eliminating all unnecessary components of traditional farming. Thinking back to the process of photosynthesis learned in middle-school biology class, we can recall the core elements to plant growth as energy, nutrients, water and CO2. Controlled environment agriculture (CEA) follows this basic formula and does away with all unnecessary inputs that have become essential to our current agriculture system, such soil and pesticides. In the CEA process, conventional elements of traditional farming are substituted with artificial ones. Rather than from the sun, plants receive energy from LED lighting that is tailored specifically to the energy needs of the plants. Instead of using soil, seeds are planted in soil-free growth mediums such as coconut husk to provide the seedlings with a surface to attach its roots to. This soilless process minimizes the risk of invasion by bugs and weeds into the growth environment, ensuring a much more clean and simple process. These seedlings are sometimes placed into growth trays which are stacked upwards, instead of outwards, in a vertical racking system. The vertical integration of plants allows for farmers to optimize the total space usage of their growth area, making it possible for farmers to reduce their land use by up to 90-99% while also increasing productivity. Plants growing in vertical farms are fed essential nutrients either hydroponically, in which nutrient-infused water is fed to the plant roots which sit in a growth medium, or aeroponically, in which the plant roots dangle freely and are misted with the nutrient-infused water.

Why do hydroponic plants have purple light?

This is also the logic behind the color of greenhouses: the green glass ensures that green light does not pass through to the plants so they only receive the colors that they most readily absorb.

Why do hydroponic plants shine purple?

If the delivery of these optimal wavelengths of light are targeted , the amount of energy being delivered to the plants can be optimized by omitting the wavelengths of light that will not be absorbed by the plants . This is the reason for the purple-ish light often seen shining on plants in hydroponic farms.

What is CEA in agriculture?

Controlled environment agriculture (CEA) follows this basic formula and does away with all unnecessary inputs that have become essential to our current agriculture system, such soil and pesticides. In the CEA process, conventional elements of traditional farming are substituted with artificial ones.

Why do we plant seeds in coconut husk?

Instead of using soil, seeds are planted in soil-free growth mediums such as coconut husk to provide the seedlings with a surface to attach its roots to. This soilless process minimizes the risk of invasion by bugs and weeds into the growth environment, ensuring a much more clean and simple process.

What is modular farming?

As a business model, modular farming also enables a much more efficient growth process, where transferring and packaging plants can be completed without causing any disturbance to other crops. Finally, with the help of soil-less growing, this modular design allows growth space to be in constant use.

What is seasonal labor?

Seasonal farm laborers are brought onto farms when it’s time to plant or harvest. These positions are typically filled by migrant workers, often with little or no education, and often making wages that fall far below the poverty line. Beyond Dollars and Cents. The problems with seasonal farm labor go far beyond wages.

How did farmers earn their living?

Farmers and their households were once able to earn a decent living by working the land, growing crops and livestock, and selling it at market prices. Today, most farm households must supplement their earnings with off-farm income, as small family farms are often not even profitable, even in a good year.

What is farm labor?

Farm labor is often a thankless, grueling, and underpaid, yet essential, job. In general, farm work was traditionally performed by self-employed farmers, their families, and hired labor brought in to help out in busy times.

What do plants need to grow?

If there’s no soil, you may be wondering, then what do the plants grow in? While we’re still just scratching the surface in our quest to understand how complex our soil microbiome is, it’s now widely believed that there are just 16 nutrients that plants require in order to grow. Three of them — carbon, hydrogen, and oxygen — are accessible through air and water exchange. The rest, along with growth hormones designed to mimic traditional soil-based systems, can be dissolved in water that circulates around the plant’s roots. H ydroponics seek to use science and engineering to efficiently mimic the vital elements of a plant’s natural environment, delivering precise quantities of nutrients at precise times.
