Spring re-growth of winter legume controls the amount of nitrogen available to the subsequent corn

Citation

The corn yields from an on-going organic cropping trial were presented and discussed. This study was characterized with using summer-seeded legume cover crops as the primary nitrogen (N) source for the corn in soybean-winter wheat-corn rotation in southern Ontario.

Plain language summary

This presentation highlighted the significance of spring termination rather than fall termination of legume cover crops as an effective N source for organic managed grain corn in S. Ontario.
