A survey of ag lands in the US shows that the Midwest is adopting cover crop usage at a faster rate than the national average.
If you remove from the total farm acreage those acres planted in hay and winter wheat, there is about 230 million acres planted in crops that could benefit from cover crops. Estimates from the survey say that cover crops were planted regularly on almost 15 and a half million acres of cropland in 2017. While that number is still below 10 percent of total cropland committed to cover crops, the good news is that the average increase is about 8 percent a year since 2012.
Better news yet is that the adoption rate in the Midwest far exceeds the national average. Whereas the nation gained just shy of 50 percent in cover crop adoption in those five years, the Midwest was at almost 80 percent increase in that time!
The above table shows that Iowa almost tripled its cover crop acres in fie years while four other Midwestern states more than doubled theirs. Indiana, an early adopter state (partly due to the work of pioneer cover crop advocates like Mike Plumer and Junior Upton) did not double the acreage devoted to cover crop use, although the state continues to lead the nation in the total number of acres planted in cover crops.
At the current rate of increase, the US would could reach 40 million acres in cover crops in this decade. Rob Myers, the regional director of extension programs for Sustainable Agriculture Research and Education (SARE), said that if rate increases elsewhere begin to follow the Midwest states’ trend, the 40 million acre figure might actually be much higher.
