No-till farming with grain legumes in organic agriculture can help the environment by reducing greenhouse gas emissions and preserving soil health. Researchers explored different methods like using cover crop mulch and intercropping to control weeds without tilling the soil. They found that no-tillage is not common in organic farming in cold climates like Sweden due to limited weed control options. Using mulch for weed control may not work well in short growing seasons, but intercropping could be a promising solution. More research is needed to make organic no-tillage farming with grain legumes successful in Sweden.
