Understanding soil nitrogen supply: organic matter quality and quantity Organic Eprints
Shepherd, Mark; Hatch, David; Hatley, Damian.
The soil organic matter (SOM) contents of organic and conventionally farmed soils were compared. Whilst the quantity of SOM was found to be similar with both systems, the quality of SOM differed in respect of higher amounts of N released by the organic soils under anaerobic incubation. This indicated a greater potential rate of mineralization and suggested that the inherent fertility of the organic soils had been improved

Using legume-based mixtures to enhance the nitrogen use efficiency and economic viability of cropping systems. Organic Eprints
Baddeley, J. A.; Döring, Thomas F.; Hatch, David; Marshall, Athole; Pearce, Bruce; Roderick, S; Stobart, Ron; Storkey, Jonathan; Watson, C.A.; Wolfe, Martin.
There is a pressing need to develop arable cropping systems that are both more efficient in their use of nitrogen (N) and more resilient to an increasingly variable and unpredictable climate. One potential solution is to use species-rich mixtures of grasses and legumes in the fertilitybuilding phase of a ley/arable crop rotation. These mixtures may reduce N losses and increase productivity of the following crop. They may also have other important benefits such as increased in-field biodiversity. In this project, legume and grass species with a range of tolerances to different environmental conditions, and with differing growth characteristics, are being grown individually and as a mixture across the UK, and their performance assessed.
