Cost-effective phosphorus management on UK arable farms (Sustainable-P)
Nutrition / 2160004 / Published: 22 August 2013
To date, there is little evidence of decreasing soil P but farmers are concerned that they may be approaching a ‘cliff edge’ of P deficiency, so that yields may soon become reduced unless P applications are resumed or increased. The specific objectives of the project are to: 1. Improve understanding of the factors affecting rates of change in soil P status with P additions from both fertiliser and organic P sources 2. Provide robust evidence on critical levels of soil P for modern combinable crops 3. Maximise and determine the value of fresh fertiliser P applications in terms of crop yield and quality under varying levels of soil P fertility
Using farm experience to improve N management for wheat (N-Monitor)
Nutrition / 2160005 / Published: 22 August 2013
The project will use a novel on-farm ‘strip trial’ approach that compares the standard N rate against 50kg/ha more and 50kg/ha less applied N to alternate tramlines. The work will help answer the question: ‘To what extent is N application rate constraining farm yields?’
Updating N fertiliser management guidelines for winter barley (Winter Barley N)
Nutrition / 2160006 / Published: 22 August 2013
The aim of this project is to review existing evidence and generate new data in order to update the Fertiliser Manual N management recommendations for winter barley.
Improving the sustainability of phosphorous use in arable farming
Nutrition / 3454 / Published: 8 November 2012
This project aims to determine if using fertiliser placement and novel fertilisers farmers can maintain soil at P index 1 (as opposed to 2) whilst consistently achieving optimum yield.
END-O-SLUDG
Nutrition / 3743 / Published: 8 November 2012
This project aims to develop a range of high quality, marketable sewage sludge based fertiliser products that meet both food and environmental safety standards.
New wheat root ideotypes for improved resource use efficiency and yield performance in reduced input agriculture.
Nutrition / 3575 / Published: 12 March 2012
The main objective of this study is to determine the impact of wheat root growth and morphology on the efficiency of nutrient uptake and hence yield and to explore how this interacts with selected environmental and agronomic parameters. We will assess the level of genetic variation for root development in a range of wheat genotypes in controlled environments and assess the performance of a sub-set of lines with contrasting root characters under field conditions. Interactions with mycorrhizal and pathogenic fungi and the effect of seed coat agrochemical applications will also be assessed. For future exploitation development of a mapping population and pre-breeding of improved lines using elite and more diverse germplasm sources will be initiated.
Minimising nitrous oxide intensities of arable products (MIN-NO)
Environment / 3474 / Published: 10 March 2010
To improve estimates of and to develop mitigation strategies (including incentivisation) for N2O emissions associated with production of major UK arable crops, in anticipation of carbon accounting at the field and farm scale.
Automating nitrogen fertiliser management for winter cereals
Nutrition / 3530 / Published: 10 March 2010
To improve profitability through increased yields and optimised N inputs by developing validated commercially-viable systems for automated, fine-scale adjustment of fertiliser N applications to autumn-sown cereal crops
Quantifying the sulphur supply from farm manures and biosolids to winter wheat crops
Nutrition / 3606 / Published: 9 March 2010
To review the major organic manures types and biosolids as a source of sulphur and quantify manure S availability for arable crop production.
Identification of critical soil P levels for cereal and oilseed rape crops on a range of soil types
Nutrition / 3554 / Published: 13 May 2009
This project aims to identify critical soil P levels for cereal and oilseed crops on different soils.
