Any kind of nutrient deficiency can reduce crop yields. Trace elements are only needed in small amounts but untreated, deficiencies can cause important crop losses. Also, crops won’t make the most of nitrogen (N) fertiliser if they can’t access the trace elements. Nutrient use efficiency is a measure of how […]
Stubbles can be a source of nutrients for next season. Different crops grown under different conditions have varying amounts of nutrients in their stubbles. Nutrient budgets can consider the amount and type of stubble. How much stubble? Stubble loads can be estimated from grain yield and the amount of growth. […]
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 […]
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. […]
During 2015 eXtensionAUS Crop Nutrition published 43 articles on many different aspects of crop nutrition in the Australian grains industry. All of these articles were prepared with, and reviewed by, members of our Community of Practice, Australia’s leading experts in crop nutrition. These are our top ten – the most popular […]
Webinar recording coming soon As part of the More Profit from Crop Nutrition national extension program,Chris Dowling presented a webinar for advisors and growers from all Australian grains regions covering the techniques for evaluating how the previous season’s crop nutrition delivered in terms of yield. The webinar covered what information you need, different measures of […]
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 […]
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 […]
Water use efficiency is widely recognised as a key performance indicator for crop production. Similarly nitrogen use efficiency (NUE) is an important indicator of resource use effectiveness and economic performance of this important crop input. Why measure NUE? Nitrogen fertilizer is frequently the biggest single cost within cropping variable costs. With […]
