Large Reductions In Agricultural Chemical Use Can Still Result In High Crop Yields And Profits

Researchers investigated whether yield, weed suppression, and profit characteristics of low-external-input farming systems could match or exceed those of conventional farming systems. Yields and profits were similar or higher in the LEI systems as in the conventional system, and lower herbicide inputs did not lead to increased weed problems. The results suggest that large reductions in agrichemical use can be compatible with high crop yields and profits.
