Description
Using five kinds of fertilizers - ammonium sulphate, ammonium nitrate, urea, ammonium phosphate and granular fertilizer, we conducted field experiment of nitrogen effect upon barley on the sand soil of the sand hill.
Granular fertilizer was dressed only as ground, but other fertilizers were dressed as ground and additional fertilizers. We could not observe any difference on the grain yield of barley among plots of ammonium sulphate, ammonium nitrate and ammonium phosphate, but we could observe that the grain yield of ureaplot was inferior in a certain degree to that of the formers, and that the growth of the barley of granular fertilizer's plot became bad since the very-young-head forming period and grain yield was very bad. We are to investigate this causes on the part 3.
