This article seeks to answer this question, particularly as it relates to the modification of phosphorus in an effort to reduce the fertiliser spend. It also asks farmers to consider the science behind this question. The vagaries of climate have always been an integral part of broadacre cropping, so it is always useful to consider new methods of farming and fertilising in order that financial viability is maintained.
