Research tracks how farmers鈥� use of cover crops and no-till changes from year to year
FRANKFORT, Ky. 鈥� A new peer-reviewed study suggests the biggest conservation challenge is not only getting farmers to try proven practices, but helping those practices stick long enough to deliver lasting benefits for soil and water.
Co-authored by Dr. Suraj Upadhaya, 91精选 assistant professor of
sustainable systems, the research examines cover crops and no-till and tracks how
farmers鈥� use of those practices changes from year to year. The study, titled 鈥淭he
Flux of Agricultural Conservation: Understanding Changes in Iowa Farmers鈥� Adoption
of Cover Crops and No-Till Over Time,鈥� is published in Society & Natural Resources.
Cover crops are planted between cash crops to help reduce erosion and improve soil
health. No-till reduces how much soil is disturbed during planting, which can help
keep soil in place and strengthen field resilience.
Instead of treating conservation as a one-time 鈥測es or no鈥� decision, the study follows
what happens over time. It found a recurring pattern of farmers trying a practice,
then pausing or stopping after a season or two鈥攁n often overlooked dynamic that can
slow broader conservation progress.
鈥淚f we measure only first-time adoption, we miss the real story,鈥� Dr. Upadhaya said.
鈥淣et conservation gains depend on whether farmers can keep practices in place year
after year, not just try them once.鈥�
The findings underscore why continuity matters. When producers start and stop practices,
annual adoption snapshots can look encouraging even while overall results remain limited.
鈥淐ontinuance and disadoption deserve as much attention as adoption,鈥� Dr. Upadhaya
added. 鈥淲hen farmers stop and restart cover crops or no-till, progress can look strong
on paper while outcomes remain modest on the ground.鈥�
Dr. Upadhaya emphasized that the study鈥檚 main takeaway extends well beyond Iowa and
can help inform how other states think about conservation strategy and support.
鈥淲hat we see in Iowa is not unique,鈥� Dr. Upadhaya explained. 鈥淚n Kentucky and across
much of the South and Midwest, the hard part is not getting farmers to try regenerative
practices, it鈥檚 helping them stick with them.鈥�
