what is the difference between manure and humus?
Manure is an organic matter composed of animal feces, wasted feed, etc. It is used as fertilizer to increase the fertility of soil. It is not the layer of soil. Manure is an excellent fertilizer containing nitrogen, phosphorus, potassium and other nutrients. It also adds organic matter to the soil which may improve soil structure, aeration, soil moisture-holding capacity, and water infiltration.
Humus is dark brown in colour and rich in minerals. It increases the soil fertility and the water retaining capacity of the soil. It is the top most layer of soil. Humus refers to organic matter that has reached a point of stability, where no further breakdown will take place and might, if conditions do not change, remain as it is for centuries.
