A Simple Way to Cut Greenhouse Gases from Corn

university of missouri develops new tilling method to reduce greenhouse gas emissions from cornNitrous oxide is a powerful greenhouse gas that comes in part from the application of nitrogen fertilizer to croplands, and researchers at the University of Missouri are documenting a simple way to make a big cut in those emissions. The low tech solution – simply tilling the soil in strips and applying fertilizer  in bands  – illustrates how significant actions can be taken to conserve energy and reduce greenhouse gases in the near future, while new technologies to manage climate change over the long run are still in development.

Tilling in Bands to Reduce Greenhouse Gas Emissions

The researchers compared strip tilling/band application to the spreading of nitrogen fertilizer across an untilled field. They found that the lower greenhouse gas emissions resulted when corn is planted and fertilized in bands of strip-tilled soil. This method sequesters the nitrogen fertilizer more deeply in the soil, saves energy, helps to prevent excess evaporation, and saves energy. In a test field, the strip/band method also produced a greater crop yield.

More Conservation Options for Farmers

If borne out by additional research, the finding provides farmers with another management tool that can boost the bottom line while cutting greenhouse gases and conserving natural resources. Further abetting this disentangling of economic growth from environmental destruction is a group of initiatives funded by the Obama administration. These include the new AgStar program which helps farmers convert manure to high value biogas and compost, and a $30 million loan and grant program that is funding more than 500 agricultural energy efficiency projects.

I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it!! So, we've decided to completely nix paywalls here at CleanTechnica. But...
