Abstract
Cover crops have been widely regarded as an effective means to reduce soil nitrate (NO3-) losses via leaching. In contrast to this known function of cover crops, they remain underutilized due to difficulties in adoption and increased costs. The goal of this project is to propose glycerol, a non-toxic and natural byproduct of biodiesel production, as a “liquid cover crop” substitute to traditional cover crops. The objectives of this project are to determine if the application of crude glycerol reduces soil NO3- levels and to evaluate soybean yield response to glycerol additions.
