Enhanced efficiency fertilisers (EEFs), including slow release compounds and urease and nitrification inhibitors, show promise for improving efficiency, increasing management flexibility, and reducing N2O emissions... Enhanced efficiency fertilisers, including controlled release fertilisers and fertilisers amended with urease or nitrification inhibitors, show promise for improving nitrogen use efficiency... The main objective of the project is to assess the benefits of enhanced efficiency fertilisers, particularly nitrification inhibitors, in mitigating nitrous oxide emissions and increasing the efficiency of nitrogen fertilisers for a range of agricultural industries, including cropping (Victoria and NSW), sugarcane (Queensland) and dairy (Victoria), under different climatic conditions that are found across Australia...

Some of the researchers from the More Profit from Crop Nutrition phase II project who recently met in Perth: (from left) Margaret Roper from CSIRO, Liam Ryan and Ross Brennan from DAFWA, Professor Zed Rengel from UWA, Roger Lawes and Elliot Duncan from CSIRO, Kelly Ryan and Craig Scanlan from DAFWA, and Louise Barton from UWA... The GRDC's More Profit from Crop Nutrition phase II program (MPCN II) aims to help growers optimise returns from fertiliser and nutrition investments by improving: the nutrient-use efficiency of crops through plant breeding; the capacity of soils to free-up and supply nutrients; the match between N, P, K, S and micronutrient applications and crop needs; and fertiliser and adjuvant product formulation and design... Researchers from the Department of Agriculture and Food, Western Australia (DAFWA), the University of Western Australia (UWA), Murdoch University and CSIRO are collaborating on 26 key national projects through MPCN II...

Given low-fertility of Australian soils and high fertiliser prices, it is clear that sustainable, low-input grain production requires cultivars that are efficient in acquisition and utilisation of nutrients, particularly nitrogen and phosphorus as the most critical nutrients in most paddocks... Potential for increasing nutrient efficiency in Australian wheat and barley germplasm will be assessed in this project via large-scale field screening of promising genotypes for nitrogen-use efficiency at a number of locations spanning a range in climate and soil conditions..... Plant pre-breeders are laying the foundation for more nitrogen-efficient varieties of wheat and barley < Keep browsing..

Nitrogen losses through volatilisation in this region are potentially high due to the alkaline soil pH, presence of lime in some soils, windy conditions and high temperatures in summer... Our preliminary lab work has demonstrated the importance of naturally occurring lime in soils for setting the potential for nitrogen losses... . If we demonstrate that current applications of surface-applied nitrogen fertiliser are leading to substantial gaseous losses to the atmosphere, farmers will review their practice and opt for less wasteful methods of fertiliser application...
