Making better fertiliser decisions for cropping systems in Western Australia. Soil test – crop response relationships and critical soil test values and ranges. Bulletin Number 4865

The Better Fertiliser Decisions for Cropping project (BFDC) (2009-2012) was completed to provide comprehensive information to improve fertiliser decisions for the cropping industry in Australia (Speirs et al. 2013a). The WA component provides interpretation of results from crop nutrient application experiments for the WA cropping system, and developed a tool for estimating nutrient losses from cropping systems soils. The BFDC-WA project aims to use the 4R principles by producing a series of bulletins on nutrient management for the cropping system of WA.
