NITROGENOUS FERTILISERS
The Experiment. Station Record, published by the .United States Agricultural Department, supplies some useful information on Comparative Experiments with different nitrogenous fertilisers. Experiments on clay sand, loam and peat soils op iiine different varieties of crops extending over a period of four years were “arranged'in order to determine the relative fertilising values of sodium nitrate, sulphate of ammonia, and lime nitrogen. The results showed "that nitrate of soda gave the best results in all cases, followed’by sulphate of ammonia and then lime’nitrogen. Sulphate of ammonia gave its poorest and best’results with potatoes, and its 'fertilising value varied from 64 to 94 per cent., of that of nitrate of soda. Lime uitrogen gave its best results with turnips, oats and cabbage. Its fertilising value varied from 23 to 85-per cent, of that of nitrate of sqda.
