Focus on nitrogen and biomass for better canola

  Not enough nitrogen is the most common limit to canola yield. The current key messages on nitrogen (N) for canola crops are: biomass is the biggest driver of canola yield low N limits biomass low biomass limits water and nutrient uptake canola crops need 80 kg of available N […]

Top advisor info at MPCN roadshow 2016

Peter Lott is an independent cropping advisor who attended the More Profit from Crop Nutrition (MPCN) roadshow at Cootamundra in August 2016. At the end of the day he shared his thoughts on some of the topics covered at the field day, and how he approaches these in his work. […]

How to review Nitrogen nutrition at 3 timely points in the season

John Angus is a researcher with the CSIRO and a mixed enterprise farmer in southern NSW. At the 2016 GRDC research updates John reported on a three stage process to make strategic decisions about Nitrogen (N) nutrition through the season for dryland farmers. Stage 1 – Prior to sowing Prepare […]

Test first, then time Nitrogen fertiliser to reduce losses

Optimal timing of Nitrogen fertiliser applications can maximise crop uptake and reduce losses to the atmosphere. Soil Nitrogen (N) dynamics in Victoria show some big differences between regions. High rates of N losses recorded from soils in the High Rainfall Zone (HRZ) emphasise how important timing of N applications can […]

What’s the minimum Phosphorus rate if you are following a poor crop?

Many growers will be thinking about what to do with Phosphorus (P) fertiliser for their next winter crop. Soil tests are the best indicator of whether a paddock is going to be responsive to P fertiliser. If your soil tests shows moderate to good levels of P, and yields were […]

Opportunities to optimise fertiliser investment – Parkes NSW

Fertiliser is a key component of crop input budgets. Key messages from the GRDC’s More Profit from Crop Nutrition (MPCN) initiative will be shared at workshop at Parkes NSW on March 9. Industry experts on soil and crop nutrition issues will present recent findings and discuss opportunities to optimise fertiliser […]

Reducing Nitrogen losses in the High Rainfall Zone of Victoria

Strategies to reduce Nitrogen (N) losses in Victorian High Rainfall Zone (HRZ) cropping systems are getting clearer. Recent research in south western Victoria examined rates of N applied, placement of fertilisers and nitrification inhibitors. This work is part of the national agricultural nitrous oxide research program, supported by the GRDC. […]

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 […]

Subsoil manuring provides long term N supply

Some growers have been able to reduce N inputs for at least three years following the placement of manure into the subsoil. Trials in Victoria’s High Rainfall Zone by Southern Farming Systems are showing promising signs of multiple benefits from subsoil manuring. Originally, subsoil manuring was primarily for improving the […]

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 […]
