Updated nutrient response curves in the northern and southern regions of Australia

The development of the Better Fertilizer Decisions for Crops database has identified gaps in the current region, nutrient and crop combinations. This project will generate data for the dominant crops in the farming sytesm that currently are under-represented in the database. Sites will be selected to develop soil test-crop response relationships and by benchmarking the less common species against wheat and sorghum, to enable the understanding of critical values to be extrapolated more generally across the industry. This project is supported by the Grains Research and Development Corporation.
