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]
For instance, sheep manure is high in nitrogen and potash, while pig manure is relatively low in both. 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]
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 ...
In the scientific literature poultry litter is usually used because chicken manure is a vague term. It could be argued chicken manure is any typical agricultural waste containing chicken excreta which is suitable for land application. Chicken manure is rarely plain feces as feces in avian species are typically combined with urine as excreta.
Even though nitrogen is a necessary element for life, too much of it in water can have negative effects on aquatic ecosystems and endanger human health. Agricultural runoff, where fertilizers containing nitrogen compounds can seep into rivers, lakes, and groundwater, is one of the main sources of nitrogen in water.
Livestock manure produces several gases including four main toxic gases, hydrogen sulfide, methane, ammonia and carbon dioxide. [4] In animal housing it is very common in swine and beef breeding to have manure storage under the building's floor. In this setup low concentrations of these toxic gases are commonly noted throughout the year. [4]
nitrogen and phosphorus, collectively known as nutrient pollution; organic matter; solids, including the manure itself and other elements mixed with it such as spilled feed, bedding and litter materials, hair, feathers and animal corpses; pathogens (disease-causing organisms such as bacteria and viruses); salts; trace elements such as arsenic;
The high quantity of manure produced by a CAFO must be dealt with in some way, as improper manure management can result in water, air and soil damage. [5] As a result, manure collection and disposal has become an increasing problem. [6] In order to manage their waste, CAFOs have developed agricultural wastewater treatment plans.
