Abstract
The value of farmyard manure in maintaining soil fertility is well known. Recently, considerable interest has been manifested in a process of making artificial farmyard manure from straw and corn stalks. The process is still in the experimental stage and only a small amount of artificial manure is being produced. However, it seems desirable to study the effect of artificial manure compared with farmyard manure on soil conditions and crop yields. The purpose of this paper is to present some results secured on the effects of artificial manures, farm manure, green manures and crop residues on nitrification in Carrington loam.
