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 […]

Using deep soil cores for Nitrogen, Potassium & Sulfur

Soil testing is a valuable tool for crop nutrition decision making. The standard 0 – 10cm soil test doesn’t always tell us enough about the crop availability of more mobile nutrients. Nitrogen and Sulphur, as anions (negatively charged), tend to move deeper into the profile with rainfall. On sandy acid […]

Deep Phosphorus fertiliser trials in NSW

Deep phosphorus (P) placement to improve crop productivity is being investigated in the central west of NSW, at Gilgandra and Nyngan. Led by Dr. Mike Bell (QAAFI), the trial investigates how deep P placement affects the fertility of the subsoil, and the economic effectiveness of deep P placement. The work […]

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 […]

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 […]

Better Fertiliser Decisions for Cropping (BFDC) workshop

BFDC Interrogator workshop Thursday 17 September 2015, Horsham. BCG with the GRDC More Profit from Crop Nutrition II program is running  a FREE Better Fertiliser Decisions for Cropping (BFDC) interrogator workshop on . The workshop is for advisors and consultants. By the end of the workshop, participants will have authorisation to use the database […]

Rain in the North – the flow on for crop nutrition

Rain received in late August in the northern grains region will help winter crops finish in NSW, but more is needed in September to make a great finish. Growers who have already top dressed should be happy, however the window is closing fast for growers to boost yield with extra nitrogen. […]

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. […]

Fertcare® Nitrogen Use Efficiency workshops

Applying the right form of nitrogen fertilizer at the right rate, at the right time and in the right place has important implications for crop profitability, greenhouse gas emissions and water quality impacts. The Fertcare® and Cotton Info Team is facilitating a Nitrogen Use Efficiency (NUE) workshop for Fertcare® participants […]

What happens to P from crop residues?

Annie McNeill from the University of Adelaide talks about the challenges in understanding what happens to the phosphorous returned to the soil in crop and break crop residues. Recorded at the National Soil Science Conference at the Melbourne Cricket Ground, November 2014. Further information National Soils Conference proceedings: Available P in topsoil […]
