Can you host a research trial in a nutrient deficient paddock?

Do you want to help with crop nutrition research? One of the GRDC’s latest research projects (UQ00082) needs nutrient deficient trial sites. The trial sites will help develop guidelines for nitrogen (N), phosphorus (P), potassium (K) and sulfur (S) for broad-leaved crops in eastern Australia.  
For cereals, we know the […]

Our top picks from the fertiliser industry conference

New science topped the agenda at the 2017 Australian Fertilizer Industry Conference. Fertilizer Australia hosted the conference in Torquay, Victoria.
Of the many presentations, the following two papers are relevant to Australian growers and crop nutritionists.

Phosphorus and soil biology
Dr Cassandra Schefe works with Monash University. Her research investigates microbe activity and available […]

Where exactly are nutrients in the soil? Does stratification matter?

Soils naturally form layers, and when nutrients concentrate in an area it’s called stratification. Soil type and agronomic practices affect stratification. Stratified nutrients can be a problem when nutrients are concentrated somewhere crops can’t access when they need them.
Mobile nutrients such as Nitrogen and Sulphur can form bulges below the […]

Do you need lime and potassium? Apply both

trail potassium plots with youtube play button

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.

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 […]

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 […]
