Soil organic matter improves soil structure so that it is more resistant to erosion and is easier to till, resulting in lower energy use and less greenhouse gas output. Soils with good SOM levels are more efficient at absorbing rainwater and storing it for plants to use in dry periods. Studies show that organic systems get around 30 percent higher yields in periods of drought than conventional systems due to the increase of SOM and its ability to capture and store water for crops.
