HOME	Synchronising nutrient supply and crop demand in modern cropping systems

NMI Home Project Outcomes Project Progress Reports Output 1 Output 2 Output 3 BCG Expo Posters 2007 Quarterly Reports to Nutrient Management Systems Nutrient Balances

Project Outcomes Project Summary This project will improve the efficiency of nutrient use by identifying factors affecting spatial and temporal supply of N and P, matching them to crop demand. This knowledge when matched with estimates of the size and dynamics (storage and rates of loss) of soil nutrient pools will be used to develop management guidelines to improve the efficiency of nutrient use in complex farming systems in 3 agroecological zones of south-eastern Australia. Output 1: A written report describing and evaluating a range of strategies designed to better synchronise nutrient supply with crop demand on both a spatial and temporal scale under varying climatic conditions and soil types. See OUTPUT 1 and Supporting Information Output 2: Dynamic mass balances constructed for N & P for different farming systems and seasonal conditions, implications for future fertiliser management determined and results written up and reported widely. See OUTPUT 2 and Supporting Information Output 3: Written documents that describe best management practices that enable growers to better synchronise N and P supply with crop demand for three agro ecological zones in southern Australia. These will include summary financial analyses of fertilizer options. See OUTPUT 3 and Supporting Information
