Higher prices for both fertiliser and grain mean that fertiliser needs to be better targeted and used more efficiently because of the increased risks of losses both at the over- and under-fertilising ends of the spectrum... The key requirements for making better fertiliser recommendations are realistic estimates of potential yield (A), knowledge of the maximum yield response to fertiliser input for a give nutrient status of the soil (B) and estimates of nutrient use efficiency or the curvature of the response curve (C)... Yield response of ryegrass to applied N is considered to be linear between applications of 0 3 00 kg N ha -1(Whitehead 1995), it was appropriate to consider the linear response to N applied in the biosolids and urea...
