manure are different in N,K,P and other elements. rate of composting, mineralization, organic carbon and other contents are different and also pH, microelements, etc

I Agree with both Hani and Saeid. I can also add that the chemical composition of the different manures will depend on the animal and  in part of its diet.

I agree with previous. I add that chemical composition of green manures will depend on plant species of green manure. 

In addition. The microflora is a very important component of the manure type. Each type has a characteristic flora. In some fertilization experiments this is of upmost importance. 

 and also, processing of manure affects contents of their material.
