Manure is recognized as an excellent source of plant nutrients nitrogen (N), phosphorus (P), and potassium (K). In addition, manure returns organic matter and other nutrients such as calcium, magnesium, and sulfur to the soil, building soil fertility and quality.
Manure is rich in nutrients, including trace elements necessary for crop growth. Approximately 70-80% of nitrogen (N), 60-85% of phosphorus (P), and 80-90% of potassium (K) found in feeds is excreted in the manure. ... Plants do not distinguish between sources of nutrients.
