Biodiesel co-product (BCP) is a low value material, produced in large quantities when biodiesel is made (constituting about 15% of biodiesel by weight). Incorporation of this material into soil as an aqueous suspension has been found to dramatically lower the fertilizer losses which occur ubiquitously in soils with medium to high rainfall, and/or irrigated soils. This is done through immobilization of the most soluble form of nitrogen (nitrate), and thus embodies a novel application for BCP to maximise nutrient use-efficiency in soils. Until now, proof of concept has been successful at the laboratory scale. However, market research, and meetings with potential investors have conclusively identified a need for evidence at the farm-scale. Rothamsted is in need of research council support to provide the data which is vital for attracting further investment, and establishing a self-supporting enterprise with the potential commercial partners identified herein.

生物柴油副产品 (BCP) 是一种低价值材料，在制造生物柴油时大量产生（约占生物柴油重量的 15%）。已发现，将该材料作为水悬浮液掺入土壤中可显着降低肥料损失，这种损失在中等到高降雨量的土壤和/或灌溉土壤中普遍存在。这是通过固定最可溶形式的氮（硝酸盐）来实现的，因此体现了 BCP 的一种新颖应用，可最大限度地提高土壤养分利用效率。到目前为止，概念验证已经在实验室规模上取得了成功。然而，市场研究以及与潜在投资者的会议最终确定需要农场规模的证据。洛桑需要研究委员会的支持来提供对于吸引进一步投资以及与此处确定的潜在商业合作伙伴建立自给自足的企业至关重要的数据。
