Manure and fertilizers contain three macro-nutrients that are the most important in plant growth: nitrogen, phosphorus, and potassium. Certain levels of these nutrients are needed in the soil according to what species of crop plant is being grown in that field, and according to what nutrients are lacking in the soil. But, fertilization is more commonly done according to the latter point: soil nutrition and quality. It is easier to judge how much fertilizer is needed because there are different mixes of fertilizer on can get, but manure is a little harder. But, the rule of thumb with the different types of manure is this: cow and horse manure tends to have higher nitrogen levels than phosphorous, and chicken manure tends to have higher phosphorous levels than nitrogen.
