Chicken manure is the feces of chickens used as an organic fertilizer, especially for soil low in nitrogen. [1] Of all animal manures, it has the highest amount of nitrogen, phosphorus, and potassium. [2] Chicken manure is sometimes pelletized for use as a fertilizer, and this product may have additional phosphorus, potassium or nitrogen added. [3]
Manure provides environmental benefits when properly managed. Deposition of manure on pastures by grazing animals is an effective way to preserve soil fertility. Many nutrients are recycled in crop cultivation by collecting animal manure from barns and concentrated feeding sites, sometimes after composting.
The linear approach expresses the rate in terms of the "amount of nitrogen and phosphorus from manure, litter, and process wastewater allowed to be applied." The narrative rate approach expresses the amount in terms of a "narrative rate prescribing how to calculate the amount of manure, litter, and process wastewater allowed to be applied. [80]

The rows formed slow surface water run-off during rainstorms to prevent soil erosion and allow the water time to infiltrate into the soil. Soil conservation is the prevention of loss of the topmost layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination
Therefore, manure is required to be composted which will ideally kill any seeds or pathogens and reduce the ammonia content. [9] A large commercial compost operation. Chicken litter, which consists of chicken manure and bedding, is an organic fertilizer that has been proposed to be superior for conditioning soil for harvest to synthetic ...
Animal manure (also referred to as animal waste) can occur in a liquid, slurry, or solid form. It is utilized by distribution on fields in amounts that enrich soils without causing water pollution or unacceptably high levels of nutrient enrichment. Manure management is a component of nutrient management.
Horses mainly eat grass and a few weeds, so horse manure can contain grass and weed seeds, because horses do not digest seeds as cattle do. Cattle manure is a good source of nitrogen as well as organic carbon. [3] Chicken litter, coming from a bird, is very concentrated in nitrogen and phosphate and is prized for both properties. [3] [4]
