Manure was used as a fertilizer on about 6,400,000 hectares (15.8 million acres) of US cropland in 2006, with manure from cattle accounting for nearly 70% of manure applications to soybeans and about 80% or more of manure applications to corn, wheat, barley, oats and sorghum. [266]
Convertible husbandry was a process that consisted of keeping arable land fallow for long periods as pasture for livestock. [2] This system utilized fertilizer in the form of animal manure. Fertilizer was used in greater quantities due to the increase in animal husbandry and resulted in benefiting crop yields when it was time for tillage. [5]

Pastured poultry also known as pasture-raised poultry or pasture raised eggs is a sustainable agriculture technique that calls for the raising of laying chickens, meat chickens (broilers), guinea fowl, and/or turkeys on pasture, as opposed to indoor confinement like in battery cage hens or in some cage-free and 'free range' setups with limited "access ...
Chicken litter, coming from a bird, is very concentrated in nitrogen and phosphate and is prized for both properties. [3] [4] Animal manures may be adulterated or contaminated with other animal products, such as wool (shoddy and other hair), feathers, blood, and bone. Livestock feed can be mixed with the manure due to spillage.
Feather meal is used in formulated animal feed and in organic fertilizer. Worldwide, approximately 50 billion chickens were used for human consumption in 2014. [1] Feather meal is made through a process called rendering. Steam pressure cookers with temperatures over 140 °C (284 °F) are used to "cook" and sterilize the feathers.
Slow- or controlled-release fertilizer: A fertilizer containing a plant nutrient in a form which delays its availability for plant uptake and use after application, or which extends its availability to the plant significantly longer than a reference ‘rapidly available nutrient fertilizer’ such as ammonium nitrate or urea, ammonium phosphate ...

Bone meal provides phosphorus and calcium to plants, along with a largely inconsequential amount of nitrogen. [4] The N-P-K rating of bone meal is typically 3–15–0 [5] along with a calcium content of around 12% (18% CaO equiv.), [6] although it can vary quite a bit depending on the source from 1–13–0 to 3–22–0.
