Crop nutrition

These ongoing projects relate to the work that HGCA has commissioned in relation to cereal and oilseed nutrition.

Click on the titles for an upshot of the problem to be addressed, the aims, the approach and the benefits to the industry. Also will be attached the latest information in the form of Annual Project Reports (APRs) or Interim Reports.

Cereals

RD-2005-3167 Development and evaluation of low–phytate wheat germplasm to reduce diffuse phosphate pollution from pig and poultry production units (SAPPIO00311) [LINK 0973a]
The purpose of this project is to reduce diffuse phosphate pollution through the production of new improved wheat lines.

RD-2006-3291 Improving cereal production by adjusting plant growth regulator inputs and the timings of nitrogen applications based on measurements of crop canopy characteristics
To examine strategies for adjusting the application of plant growth regulators and the timings and splits of nitrogen fertiliser applications based on information collected using boom mounted sensors. These strategies will aim at minimising the risk of lodging whilst also minimising growth regulator use.

RD-2007-3375 Soil and grain nitrogen analysis to provide up to date Scottish data to aid revision of N fertiliser guidelines
The project aims to generate contemporary data on effects of nitrogen input on crop yield, grain nitrogen and soil N reserves, to aid revision of Scottish NVZ guidelines.

RD-2007-3425 Establishing Best Practice for Predicting Soil Nitrogen Supply (SNS)
The project aims to achieve consensus across the industry on best practice for estimation of soil N supply

RD-2008-3189 Cost-effective sampling strategies for soil management
The overall aim of this project is to develop a rational strategy for practical field sampling for nutrient content of soils, to ensure that inputs meet crop requirements and that significant areas of excess or inadequate nutrients do not emerge.

RD-2007-3447 Using legume-based mixtures to enhance the nitrogen use efficiency and economic viability of cropping systems 
The project aims are to improve fertility building in organic rotations through use of a mixture of a wide range of leguminous species and to provide more efficient transfer of nitrogen to the subsequent crop

RD-2008-3530 Automating nitrogen fertiliser management for winter cereals 
Project aims 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

RD-2008-3606 Quantifying the sulphur supply from farm manures and biosolids to winter wheat crops 
Project aims to review the major organic manures types and biosolids as a source of sulphur and quantify manure S availability for arable crop production.

Oilseeds

RD-2008-3507 Assessing the benefits of using foliar N on oilseed rape 
The project aims to develop independent guidelines that describe how to make the best use of late foliar nitrogen applications on oilseed rape.

RD-2008-3578 Optimising the N rate and timing for semi-dwarf oilseed rape 
The aim of this project is to investigate whether semi-dwarf oilseed rape has a different optimum N rate and N timing from standard height varieties.
