    Massive changes have taken place in the nutrient management of Australian crops and pastures in the past three decades. Before then the supply of nutrients had been mostly from soil reserves (apart from phosphorus fertiliser, which has been routinely applied in the south), but during the three decades those reserves have declined and plant demand is increasingly met by fertilisers. Additional amounts of nutrients are needed to meet the requirements of higher yielding crops, the increased crop area stimulated by conservation agriculture (CA) and the reduced area of pastures and their supply of residual nitrogen from biological fixation.
