Super- phosphate (56 lb. Per acre) was used last year on immediately adjacent soil with very gcod results. More grain was obtained and the sample was much better. " EFFECT OF SUPERPHOSPHATE ON WHEAT YIELD, N. S. W. 7 At the outset of the investigation, before commencing work with the soils, several of the recommended methods for the estimation of phosphoric acid were tested. Of the official methods, "The Provisional Official Method" (Wiley, "Principles and Practice of Agricultural Analysis, " V...ol. I, page 514) was chosen as likely to give consistently accurate results with a minimum expenditure of time and labour. The following is an outline of the method: To the solution containing the phosphate, 20 c. C. Of nitric acid and 25 c. C. Of 50 per cent, ammonium nitrate solution were added, and the liquid heated to 50 degrees C. A solution of ammonium molybdate was also brought to this temperature, and sufficient to ensure the complete precipitation of the phosphate as ammonium phospho-molybdate added slowly and with constant stirring, the vessel then being stood in a warm place until preci- pitation was completed.
