For centuries, animal manures have been used to help foster the growth of agricultural crops. Perhaps the most important aspect of manure is that it adds wonderful organic matter to the soil. In terms of actual plant nutrients, manure products are much lower than most standard granular products.

Listed below are the major nutrient element content of various types of livestock manure in either the dry or undried form. The numbers represent the percentage of each found. For example, undried i.e. straight from the cow, cattle manure would have an analysis of 0.5-0.3-0.5 if it were sold as a bag of fertilizer. In 100 pounds, there would only be 1/2 pound of nitrogen, 3/10 of a pound of phosphorus and 1/2 pound of potassium.
