Novel Nutrient Sources For Enhancing Soil Nutrient Recycling in Cropping Systems of the Prairies

土壤保持的一个重要方面是养分循环。植物和动物从土壤中吸收的养分需要返回到土壤中，以保持生产力并减少我们对新肥料养分来源的依赖。生物燃料-生物能源工业的扩张导致这些过程的含营养物的副产品的可用性增加，这些副产品具有作为肥料的潜在用途。拟议的研究计划将调查生物能源生产的各种副产品及其在添加到土壤中时作为植物有效磷和氮的宝贵来源的潜力。

An important aspect of soil conservation is nutrient recycling. Nutrients that are taken from the soil by plants and animals need to be returned to the soil to maintain productivity and reduce our reliance on new sources of fertilizer nutrient. The expansion of the biofuel-bioenergy industry has led to the increased availability of nutrient containing co-products of these processes that have potential use as fertilizers. The proposed research program will investigate various co-products of bioenergy production and their potential to serve as valuable sources of plant available phosphorus and nitrogen when added to the soil.
