How do you assess how well last season’s crop nutrition management shaped up? Every grower knows how much they spend on crop nutrition. They do not always know if it was well spent. A good crop nutrition program maintains soil fertility, and supplies what is needed to meet the productivity […]
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 […]
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 […]
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 […]
Crop nutrition talk is a summary of online ‘chatter’ from the week in twitter – that is at least partly on topic for crop nutrition. It’s perfect for people who don’t use twitter but would like to know what’s going on, or for those who use twitter but like it filtered […]
Critical soil nutrient levels indicate whether a yield response to fertiliser is likely – or not. Their role is to help avoid unnecessary or uneconomic applications of fertiliser. Critical levels are used in interpreting soil test results to make fertiliser recommendations.
The critical level is the value required to achieve 90% […]
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 […]
Many growers put in paddock test strips to investigate yield response to fertiliser or other crop amendments. The value of test strips can be lost if harvest is not planned to capture yield information. Growers and advisors with test strips in place should be talking with each other about how […]
