- ON THE INFLUENCE OF MANURE UPON THE NATURE OF DRAINAGE WATER AND SOIL : LYSIMETER EXPERIMENT.
抄録
1) Rotated barley (Naked seed) and upland rice in no manure plot, no N plot, no P_2O_5 plot, no K_2O plot, three manures plot, CaCN_2 plot, urea plot, soybean cake plot, rape seed meal plot, herring cake plot for two years (1933-1935). 2) Average temperature in the period of experiment was much the same to late 10 years average temperature, but rain fall differed more or less from late 10 years average rainfall. 3) The amount of drainage water was 55-70% average 64% to irrigation water & rainfall at barley cropping and 15-30% average 22% at upland rice cropping, and yearly 34-50% average 44%. 4) In no N plot, the growth of crops was very poor, so therefore the amount of drainage water was larger than that of other plots. 5) In CaCN_2 plot, the amount of drainage water was less than that of other nitrogenous plots. 6) pH va1ue of drainage water changed periodically between 5. 6 & 7. 5 namely high at summer time and low at winter season. Generally pH value of drainage watar was low by the addition of ammonium-sulphate. 7) The amount of various nutrients in drainage water one year per 1 ha was as follows, NO_3-N...16-34kg, NH_3-N...1-2kg, P_2O_5......0.04-0.16kg, K_2O......34-68kg CaO......75-150kg, MgO......30-80kg, SO_4......93-450kg 8) Addition of ammonium-sulphate made the reaction of soil acidic and the amount of exchangeable bases especially CaO was 1ess than original soil.
