Researchers found that a 1% increase in no-tillage adoption within a county can increase agricultural land value by $7.86 per acre across 12 Midwestern states covered by the OpTIS database: Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, Ohio, Oklahoma, South Dakota and Wisconsin. Using data specific to Iowa they concluded 1% adoption of no-till at the county level increases farmland values $14.75 (and possibly more) per acre inside Iowa.
