Do you need lime and potassium? Apply both

Large areas of West Australian cropping soils have low potassium (K) reserves. Acidity also constrains most of these soils.  Potassium deficiencies have become more widespread with intensive cropping, removal of hay or stubbles, and K fertiliser inputs lower than removal rates.

Rob Norton recognised for excellence at fertiliser conference

Rob Norton

Congratulations to Rob Norton, who last night received an award recognising his long contribution to the Fertilizer industry, from Fertilizer Australia. Rob, the Regional Director of the International Plant Nutrition Institute (IPNI), is also the chair of extensionAUS’s crop nutrition Community of Practice. The award was presented at the conference dinner for the 2017 […]

Watch: how to use plant tissue tests for better results

Chris Dowling explains the keys to successful sampling and interpretation of plant tissue tests in winter crops.
Why use tissue tests?
Plant tissue tests ask the crop ‘what’s wrong?’. Ideally, analysis can get to the core of an issue before yield has been overly compromised.
Plant tissue results are more sensitive […]

Level up your Nutrient Performance Indicators

infographic about the optimal nutrient performance indicator results for a paddock.

Nutrient performance indicators (NPIs) assess how effective and efficient fertiliser applications have been. Last week we talked about using Partial Factor Productivity (PFP) and Partial Nutrient Balance (PNB) together. Those NPIs give you a good idea if your fertiliser investment was worthwhile, and if your paddock nutrient status is stable […]

Deep placement of fertiliser delivers results

Mike Bell, expert in deep fertiliser placement, smiling in paddock

Effective deep application of phosphorus (P) and potassium (K) fertiliser relies on critical factors. Understanding how to tune important variables in deep applications is emerging from trials in the northern cropping region (central and southern Queensland, and northern NSW).
The critical factors for successful deep applications include:

placement
product choice
formulation
compatibility of compound products
soil […]

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 […]
