Abstract

Biological nitrogen fixation can offer an alternative to the reliance of cereal production systems on synthetic nitrogen applications. The use of synthetic nitrogen is threatened due to the high greenhouse gas emissions associated with its manufacture and use. To reduce reliance on synthetic nitrogen, legume fallows can be included in crop rotations. Field trials found that legume fallows with a higher proportion of sown legume species in proportion to grass and herbs had higher soil nitrate levels and improved initial establishment of the following barley crop. The difference in soil nitrate levels in the top 5-15cm and 15-25cm became less pronounced as the winter after the legume mixes were destroyed progressed, and by February the number of barley plants and the soil nitrate levels did not differ between the previous species sown.
