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.

Build up nitrogen with biserrula in Western Australia

Inspecting a biserrula pasture with annotation of the crop sequence for the paddock

Biserrula is proving a beneficial pasture legume for cereal crop rotations in Western Australia. This persistent annual legume can be used to rest and rehabilitate heavily cropped country, and to manage weeds. Used in pasture phases, it can leave plenty of nitrogen available for future crops, and eventually provides good grazing […]

In tough conditions crops do better with potassium

Having sufficient potassium reduces crop damage in frost events. Field trials in Western Australia showed benefits from potassium in wheat and canola. Richard Bell is a researcher at Murdoch University. In this video he explains:

Crops respond more to potassium fertiliser in seasons that stress the plants with drought or frost […]

Potassium and crop stress

Crops may need extra Potassium when they under stress from drought or frost. There is a theoretical basis, and now GRDC funded research is looking into whether applying additional potassium is worthwhile when plants are under stress.
Getting the right combination of drought and frost conditions to get meaningful results from […]

Claying and crop nutrition

Claying by delving brings subsoil clays up to the surface. It’s a proven treatment for water repellency. Integrating clays into sandy topsoils also changes their nutrient status. What happens depends on the specific clay material involved.
Testing of clay material prior to spreading or delving is very important to ensure a […]

Nitrogen Use Efficiency training online

Significant new research is investigating how management of nitrogen fertilizer can be optimised for crop profitability, alongside minimising greenhouse gas emissions and impacts on water quality. Fertcare® has brought this new information, along with a summary of existing best science and their practical implications into a training package.
Following a series […]

How Australian crop advisors make quality fertiliser recommendations

Crop nutrition and better fertiliser decisions for cropping webinar, presented on 8 October 2015 by Tony Cox, NSW DPI, National Coordinator for the More Profit from Crop Nutrition II program, funded by the GRDC.
The webinar introduced the BFDC database and the Interrogator that enables crop advisors to ensure their fertiliser […]

Zinc deficiency shows up in the cold

The cold snaps seen in southern Australia this year gave conditions where zinc deficiencies typically appear. Zinc deficiency tends to occur early in the growing season when soils are cold and wet. Shoot growth then outpaces root development. Root-pruning herbicides can induce zinc deficiency by the same mechanism. Zinc deficiency […]

Correcting micronutrient deficiencies

Ross Brennan from DAFWA talks about a current micronutrient project funded by the GRDC as part of the More Profit from Crop Nutrition II Program.
Recent GRDC funded research in Western Australia showed that both foliar sprays and nutrient applications to soil are very effective in correcting micronutrient deficiencies in crops. Applying […]
