Harnessing the nitrogen cycle through novel solutions

Sustainable land management requires that we optimise nitrogen (N) supply for plant production and also minimise soil nitrogen losses through nitrate (NO3) leaching and nitrous oxide (N2O) gas emissions. To achieve this it is necessary to understand how management practices ...

Organic residues & soil mixing alter plant available nitrogen

Despite our understanding of plant nitrogen (N) uptake and soil N dynamics in arable systems, the supply and demand of N are infrequently matched as a result of variable seasonal and soil conditions. Consequently, inefficient N use often leads to constrained production and can contribute to poten ...

Managing Soil Organic Matter

Most growers view soil organic matter as a key component of soil productivity, but the capacity to increase organic carbon (measurable component) in soil is constrained by soil type, climate and – to a lesser extent – management. Detectable changes usually occur slowly, over decades t ...
