Abstract

Fertiliser costs represent 20% to 25% of variable costs for growing grain crops. This proportion is likely to increase with the continued decline of soil organic matter and corresponding reduction in annual soil mineralisation of nitrogen (N) (e.g.Angus and Grace 2017). In approximate terms,the N mineralisation potential in cropping soils is declining by 50% every 25 to 30 years. Soil mineralisation of N is not enough to meet crop demand, consequently N fertiliser is typically applied to wheat at sowing, stem elongation and occasionally at booting. The in-crop efficiencies of fertiliser N retrieval vary greatly, with approximately 44% in above-ground plant parts, 34% in soil and 22% not recovered, which is presumably lost (Angus and Grace 2017). Increases in the efficiency with which wheat extracts fertiliser N from the soil can result in substantial fertiliser savings.

Conference

Conference	GRDC Grains Research Update (Wagga Wagga)
Abbreviated title	Strategic Steps - Enduring Profit
Country/Territory	Australia
City	Wagga Wagga
Period	13/02/18 → 14/02/18
Other	Ensuring growers, advisors and industry stakeholders are informed about the latest research and development outcomes in their quest to improve on-farm profitability is a key role of the annual Grains Research and Development Corporation (GRDC) Updates. The GRDC Updates deliver research direct to growers, agronomists and industry. This year the Updates will offer information from the latest research and development from short- and medium-term investments that address on-farm priority issues from farming systems, agronomy, soils, weeds to pests and diseases.
