How much plant nutrients are in manure?
There is huge variability in what people call “manure”. Hog manure is drastically different from poultry manure and both are quite different from beef feedlot manure. Even the nutrient content of feedlot manure is not consistent because of varying amounts of bedding and animal waste that make up the “manure”. The only way to accurately know the nutrient levels in manure is to have a lab analysis of a representative sample. If lab analyses are not available, the following table can be used to estimate the plant nutrients in manure from various sources.
