The research looked at different ways to grow corn more efficiently and economically. By studying different crop rotations and tillage methods over 20 years in Ontario, Canada, the researchers found that diversifying crops and using certain tillage methods can increase corn yields and profits. Rotating corn with soybean or wheat can boost yields by 5-11%, leading to higher yearly profits. Diversified rotations also reduce financial risks for farmers and are less affected by changes in prices or energy costs. Using red clover as a cover crop can improve corn yields in some cases. Overall, diversifying crops and using the right tillage methods can help farmers grow more corn and make more money.
