This Small Business Innovation Research Phase I project examines the feasibility of novel controlled release methods of herbicide delivery that will significantly limit pollution due to agricultural runoff. The research utilizes natural layered minerals that are able to sequester and later release herbicides gradually into soils or foliage; and will examine the feasibility of developing time-delayed release agents that will prevent dissolution and runoff of herbicides during critical heavy rainfall events. Further, the research effort will examine the feasibility to utilize an intensified process to prepare the proposed composites, a process which is carried out at room temperature, involves only a single step, produces no by-products, and renders the proposed product highly cost-effective for its end customers. The broader impacts of this research will be development of cost-effective products that mitigate the environmental impact of agricultural runoff (one of our nations most significant sources of pollution), and will mitigate the concomitant collateral damage (both environmental and economic) to our nations fisheries. Customers, such as nurseries, greenhouse growers and farmers, will derive several benefits from products resulting from this research: a time-delayed, controlled-release product may potentially eliminate the need for multiple applications of herbicides, will minimize exposure of workers to harmful herbicides, may potentially limit or eliminate herbicidal runoff to adjacent watersheds, and may provide significant cost-savings.

这个小型企业创新研究第一阶段项目考察了新型除草剂释放控制释放方法的可行性，这种方法将显著限制农业径流造成的污染。这项研究利用能够将除草剂逐渐隔离并随后释放到土壤或树叶中的天然层状矿物；并将研究开发延时释放剂的可行性，以防止除草剂在关键的暴雨事件中溶解和径流。此外，研究工作将研究利用强化工艺来制备拟议复合材料的可行性，该工艺在室温下进行，只涉及一步，不产生任何副产品，并使拟议产品对其最终客户来说具有很高的成本效益。这项研究的更广泛影响将是开发成本效益高的产品，以减轻农业径流(我们国家最重要的污染源之一)对环境的影响，并将减少随之而来的对我们国家渔业的附带损害(环境和经济)。客户，如苗圃、温室种植者和农民，将从这项研究产生的产品中获得几个好处：延时、控释产品可能消除多次使用除草剂的需要，将工人对有害除草剂的暴露降至最低，可能限制或消除邻近流域的除草剂径流，并可能提供显著的成本节约。
