What is the difference between natural and commercial urea?

Urea is a popular ingredient in many commercial fertilizers, almost replacing ammonium nitrate as fertilizer in many large farming operations. These urea-based products have artificially produced urea in most cases. But, naturally produced urea can have similar yet less impactful benefits.

What is the best fertilizer for organic crops?

Animal-based fertilizers available to both organic and conventional growers include blood meal, bone meal, feather meal and fish meal. Of these, feather meal (13-0-0) is highest in nitrogen and bone meal (1-13-0) is highest in phosphorus. Fish meal has a 9-3-1 percent NPK makeup and blood meal is 12-0-0. Like cottonseed meal, these animal-based fertilizers will be slow release and the nitrogen component will not be immediately available to crops.

What fertilizer is used in organic farming?

The most commonly shared manure-based fertilizer used by both conventional and organic farmers is chicken litter. Nutrient component varies widely from one chicken farm to another and there is variation from one poultry house to another on the same farm.

How does worms affect crop yield?

By strengthening earthworm populations, farmers can better leverage soil organic matter to improve nutrient efficiency — particularly nitrogen — and boost crop yield .

How much nitrogen does alfalfa add to the soil?

Because nitrogen-fixing bacteria live in legume root nodules, a well manged legume crop such as alfalfa can add 25 to 75 pounds of nitrogen per acre, per year.

What is the percentage of soybean meal?

Soybean meal has 6-1-4.2 percent, respectively, nitrogen, phosphorus and potassium. Cottonseed meal is 6-2-1, alfalfa meal is 4-3-1 and kelp meal is 1-0-2. Any of these meals can be used on organic crops, regardless of whether they came from plants grown certified organic.

How long do ruminants have to graze?

Organic ruminant livestock—such as cattle, sheep, and goats—must have free access to certified organic pasture for the entire grazing season. This period is specific to the farm’s geographic climate, but must be at least 120 days. Due to weather, season, or climate, the grazing season may or may not be continuous. Organic ruminants’ diets must contain at least 30 percent dry matter (on average) from certified organic pasture. Dry matter intake (DMI) is the amount of feed an animal consumes per day on a moisture-free basis. The rest of its diet must also be certified organic, including hay, grain, and other agricultural products. No. Ruminant livestock must graze on certified organic pasture throughout the entire grazing season for the geographic region. Depending on region-specific After an animal reaches the 120-day grazing minimum, does that mean it no longer needs to be on pasture? environmental conditions (e.g., rainfall), the grazing season will range from 120 to 365 days per year. Per the USDA organic regulations, the grazing season is the period of time when pasture is available for grazing due to natural precipitation or irrigation. Outside the grazing season, ruminants must have free access to the outdoors year-round except under slaughter stock are exempt from the 30 percent DMI from pasture requirement for the last fifth of their lives (up to 120 days). To access worksheets on calculating DMI from pasture, visit www.ams.usda.gov/NOPProgramHandbook.

What is organic certification?

Organic certification verifies that livestock are raised according to the USDA organic regulations throughout their lives. www.ams.usda.gov/organicinfo Like other organic products, organic livestock must be: – Produced without genetic engineering, ionizing radiation, or sewage sludge. – Managed in a manner that conserves natural resources and biodiversity. – Raised per the National List of Allowed and Prohibited Substances (National List). – Overseen by a USDA National Organic Program- authorized certifying agent, meeting all USDA organic regulations.

How to determine if a farm complies with the USDA organic regulations?

To determine if a farm complies with the USDA organic regulations, certifying agents review the farm’s written organic system plan and on-site inspection findings. Prevention. Since organic farmers can’t routinely use drugs to prevent diseases and parasites, they mostly use animal selection and management practices.

How should organic livestock be raised?

Organic livestock must be raised in a way that accommodates their health and natural behavior: – Access to the outdoors – Shade – Clean, dry bedding – Shelter – Space for exercise – Fresh air – specified conditions (e.g. inclement weather). Ruminant Clean drinking water – Direct sunlight Organic management reduces stress, reducing the incidence of diseases and supporting animal welfare.

What are the benefits of organic farming?

Organic livestock production and pasture-based systems provide many benefits: . Environment. Organic farmers and ranchers use practices that minimize impacts to the off-farm environment. They implement plans to avoid manure runoff, instead using manure as fertilizer or composting it to conserve nutrients.

What is the purpose of pasture based diet?

Animal Health. Pasture-based diets improve ruminants’ digestive health, making the rumen (first stomach) less acidic. This lower acidity increases the number of beneficial microorganisms that help ferment ruminants’ high-fiber diet. Pasture-based systems have been shown to reduce hock lesions and other lameness, mastitis, veterinary expenses, and cull rates.
