How critical is the critical level?

Critical soil nutrient levels indicate whether a yield response to fertiliser is likely – or not. Their role is to help avoid unnecessary or uneconomic applications of fertiliser. Critical levels are used in interpreting soil test results to make fertiliser recommendations. The critical level is the value required to achieve […]

How is extension for crop nutrition evolving?

Over 7000 people engaged with the MPCN Northern Region program in 2012 – 2015. The More Profit for Crop Nutrition (MPCN) program aimed to improve returns from fertiliser. The program funded research and extension on soil and crop nutrition. The e-Extension and Training projects integrated the latest advice. Growers and […]

Nutrient Performance Indicators for your paddocks

text as graphic about why nutrient performance indicators are used.

Nutrient performance indicators (NPIs) are calculations you can do to assess how effective and efficient fertiliser applications have been. Underusing fertiliser limits crop yield and can draw down soil reserves. Unless building soil reserves, overuse is a waste of money, as excess nutrients can be lost and may cause environmental […]

Make the most of your fertiliser budget with the Four Rs

The ‘Four Rs’ is a nutrient management framework that aims to match nutrient supply with crop needs. The Four Rs The four components of the framework are: The RIGHT source fertiliser   At […]

Get the most out of soil testing 2017

Soil testing informs crop nutrition decisions. Collecting representative samples is the most important step in getting useful information. Plan your soil sampling Map non-uniform paddocks into zones. Base the zones on observed soil differences (or EM38 maps if available), and sample them separately. Use a sampling plan within zones. Grids, […]
