Extract

Field experiments with maize at the Bahtim Experimental Station and laboratory tests indicate that the lower efficiency of ammonium sulphate as compared with nitrate of soda is due principally under these special conditions to the liberation of ammonia from the fertiliser in contact with an alkaline soil. The rate of this liberation is a function of the aeration and of the soil reaction.
