(AMES, IA) — A new study from Iowa State University sheds surprising light on the evolving landscape of agricultural conservation in the state. It found that many farmers who adopted two key conservation practices, including cover crops and no-till, didn’t continue using those practices over time. The research explored farmers’ self-reports of whether they adopted, continued, or abandoned the conservation practices between 2015 and 2019. Most conservation adoption research operates under the assumption that once a practice has begun, it will remain in use.
The farmer survey shows that almost 20 percent of farmers who used cover crops in one year had stopped using them by the following year. For cover crops, 192 farmers moved to an adopter status during the study period. However, 142 shifted out of the adoption category, leaving a net gain of 50 people. That’s an overall adoption increase of 1.9 percent. The no-till adoption gain was only 26 individuals.
