Frost damage and copper deficiency just look similar

Crop damage caused by frost looks a lot like copper deficiency. Leaf damage extends back from the tip of the leaf. Damage to seed heads can be easily confused too. Other than similar symptoms, there’s little evidence yet to link frost and copper deficiency.
The location of damage can help with […]

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.

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 […]
