|Title:||Exploring the potential for site specific nitrogen management in grazing systems||Contributor(s):||Anderson, Samantha (author); Trotter, Mark (author); Haling, Rebecca (author); Edwards, Clare (author); Guppy, Christopher (author) ; Lamb, David (author)||Publication Date:||2012||Handle Link:||https://hdl.handle.net/1959.11/10498||Abstract:||The application of site-specific nutrient management (SSNM) in grazing systems may offer considerable benefits in terms of optimised nutrient use efficiency and pasture productivity. There is significant variability in soil nutrients and plant growth potential across pasture paddocks, suggesting that SSNM may prove viable (Virgona and Hackney, 2008). Research has led to increasing uptake of SSNM in cropping systems. Despite this, there has been little research into the value of SSNM strategies within more complex grazing systems and even less is know about how producers might implement these techniques. This experiment examines the value of SSNM of nitrogen (N) in a pasture using soil EM38 mapping to guide paddock zoning for variable rate fertiliser application. Soil EM38 is strongly linked to soil moisture characteristics and this study explores how variability in soil water may influence nutrient use efficiency at the sub paddock scale.||Publication Type:||Conference Publication||Conference Name:||3rd Australian and New Zealand Spatially Enabled Livestock Management Symposium, Lincoln, New Zealand, 6th July, 2012||Source of Publication:||Proceedings of the 3rd Australian and New Zealand Spatially Enabled Livestock Management Symposium, p. 25-25||Publisher:||AgResearch Grasslands||Place of Publication:||Palmerston North, New Zealand||Field of Research (FOR):||070104 Agricultural Spatial Analysis and Modelling||HERDC Category Description:||E3 Extract of Scholarly Conference Publication||Statistics to Oct 2018:||Visitors: 409
