Purdue Study Finds Benefit to No-Till Farming

Researchers at Purdue University reported last month the results of a study on no-till farming and crop rotation – that using these practices in farm fields can significantly reduce field emissions of nitrous oxide, a greenhouse gas.

Specifically, no-till farming – leaving crop residue on the soil and not using a tractor to turn it up – reduce nitrous oxide emissions by more than 57 percent over chisel plowing, the most common tillage practice.

Long known for benefits to water quality and soil conservation, the study suggests that there is a significant air quality benefit as well, according to Tony Vyn, Purdue professor of agronomy who led the study team.

Last March, my colleague Nick Weber blogged here about all the different factors that can affect weed management and weed control – and no-till farming was one of the most important.

The U.S. Department of Agriculture funded the Purdue research via the Consortium for Mitigation of Agricultural Greenhouse Gases at Kansas State University. Related on-farm research underway by Purdue is being funded by the Indiana Corn Marketing Council and Dow AgroSciences.
