  1. Grow cover crops when the field is empty

    A review of 120 papers testing interventions on a range of soils largely in Japan, found enhanced soil organic carbon storage under cover crop management, no-tillage practices and manure (and other organic by-products) application. Longer-term cover crops resulted in considerable increases in soil organic carbon. In the review, research by Wagger (1988 & 1989) found that carbon input to the soil was greater under legumes due to their lower lignin and cellulose (substances which form cell walls in plants) content, and because legume growth is not limited by nitrogen availability in the soil. Balanced and integrated increases in the soil organic carbon pool, lessening of non-carbon dioxide emissions, and control of soil nutrients based on location-specific recommendations are also needed. No review methods were specified. Tillage systems reviewed included: no-tillage, conservation tillage (surface residues retained), conventional tillage (mouldboard plough, rotary tillage, disced). Cover crops reviewed included a mix of leguminous and grass covers: rye Secale cereale, hairy vetch Vicia villosa, and crimson clover Trifolium incarnatum.

Cover crops reviewed included a mix of leguminous and grass covers: rye Secale cereale, hairy vetch Vicia villosa, and crimson clover Trifolium incarnatum.
