The objective of this investigation was to compare different application methods whereby ammonia losses from nitrogen fertilizers can be limited when applied to alkaline soils. Three application methods were simulated, namely broadcasting, ploughing under and band placement. Five nitrogen fertilizers, namely (NH4)2SO4, LAN, urea, MAP and DAP were applied at a rate of 120 kg N ha-1 to five soils which ranged in clay content between 7,6 and 49,9%. The pH(H2O) of the soils was adjusted to… CONTINUE READING
