Ground Cover Supplement : GC Supplement - Profit from crop nutrition 2013
2 Introduction Regional crop nutrition guidelines by Peter Morrison The second phase of the More Profit from Crop Nutrition (MPCN II) program will run until 2017 with a strong focus on developing regional crop nutrition guidelines and extension of these guidelines via on-farm workshops and industry training. MPCN II brings together 23 crop-nutrition- related projects and is coordinated by Dr Simon Speirs, New South Wales Department of Primary Industries. There is a focus on unravelling regional and local-level crop nutrition issues in each of the GRDC growing regions. This supplement outlines the proposed approaches across the western, southern and northern regions and summarises some of the research results and extension activities achieved to date. Many of the current soil testing practices and critical values were developed before the widespread adoption of minimum tillage across Australian cropping systems. Regional crop nutrition guidelines are being developed through the second phase of the More Profit from Crop Nutrition program. Dr Simon Speirs Cover photo: Emma Leonard GROUND COVER SUPPLEMENT edited by Janet Paterson Nutrient stratification and depletion, along with higher yield expectations and modern crop varieties, mean it is time to revisit these historical practices and guidelines to accommodate new farming systems, crops and issues. For example, long-term nutrient depletion from deep in the soil profile of northern region soils is forcing a rethink in fertiliser management of these soils. Research by Dr Mike Bell and colleagues in Queensland and northern NSW is establishing the extent of, and ways to overcome, this depletion issue (see page 9). On the other side of the country, in the western region, many growers have an oversupply of phosphorus in the once highly deficient soils of this region. Here MPCN II research is focused on how to profitably and safely divert fertiliser dollars into lime applications to overcome the widespread and growing acidity issue across the Western Australian wheatbelt (see page 6). In the southern region the increasing area sown to pulse and oilseed crops has highlighted gaps in our knowledge about nutrition management for these crops. Sulfur and potassium are a particular focus for MPCN II research in the southern region. Central to the second phase of the MPCN program is the further development of the Making Better Fertiliser Decisions for Cropping Systems in Australia (BFDC) database and promotion of the database as the 'go-to' source for soil test/crop response curves for Australian cropping systems. The BFDC database is an integration of more than 5000 Australian crop nutrition trials carried out over the past 50 years. The overriding goal of the database is to gather consistent and reliable crop nutrition data into a single, easily accessible location so that the grains industry can make better fertiliser decisions. Continued development of the BFDC database, along with accreditation schemes such as the Fertcare® Accredited Advisor scheme, Australasian Soil and Plant Analysis Council certification and National Association of Testing Authorities accreditation, will help move the grains industry towards best practice fertiliser decisions. □ More information: Peter Morrison, 02 6166 4500, email@example.com Ground Cover is brought to you by growers and the Australian Government through the publisher, the Grains Research and Development Corporation (GRDC).
