Introducing grain legumes, such as pea crop, in the cropping systems to reduce net GHG

This practice abstract presents the introduction of grain legumes, such as pea, faba bean and soybean, into arable cropping systems to improve environmental performance and reduce greenhouse gas emissions.

Grain legumes fix atmospheric nitrogen through their symbiotic relationship with soil bacteria, reducing the need for synthetic nitrogen fertilisers. Their inclusion in crop rotations can decrease nitrogen inputs, improve the carbon balance of farms and increase the yield potential of subsequent crops.

Additional benefits include improved soil health, enhanced biodiversity, greater crop diversification, lower production costs and increased resilience of farming systems. Combining grain legumes with cover crops can further strengthen climate mitigation benefits.
