| Arbuscular mycorrhizal fungi (AMF) are potential contributors to plant nutrition and pathogen suppression in low input agricultural systems, although individual species of AMF vary widely in their functional attributes. Recent studies at HRI and elsewhere have suggested that in some agricultural systems inoculum of AMF is substantially lower under conventional management relative to that under organic management. Further studies have suggested that conventional management selects AMF communities with limited benefits to their plant hosts relative to those in organic systems. There is a need to investigate the generality of these findings, and their implications for the productivity of organic systems, particularly during the period following conversion to... |

| Optimising the amount of nitrogen captured by fertility building crops is essential for successful organic farming. This study used a combination of literature review, empirical measurements, model development and farmer participation to produce improved guidelines on making the most of soil nitrogen for organic farmers and growers. The main field experiment examined the impact of cutting and mulching on the build up of soil nitrogen. Recommendations to organic farmers from this part of the work, are that cutting and removing herbage during the fertility building phase promotes the highest amount of nitrogen fixation. However the highest soil residues occurred when clover was mulched in situ. Application of organic manures to legumes should also be avoided... |
