项目摘要

Hillsdale Fur Farm is a large mink production ranch located in Nova Scotia, Canada. The farm generates approximately 120,000 pelts annually representing annual revenue of over $9 million. A significant challenge in managing intensive commercial livestock operations relates to the generation of nutrient-rich,organic by-products such as manures, used bedding, and wasted feed. The nutrient-rich by-products pose an environmental concern if they reach water sources, a large disposal cost to the production system, and a lost opportunity if not used. Hillsdale Fur Farm is currently exploring avenues to manage high nutrient concentration surface runoff water which is collected in holding ponds, as well as examining approaches to develop additional value opportunities from use of the water as a fertigant. Short term rotation coppice plantation systems using willow (Salix) for production of biomass as an alternative fuel, or for value addition through extractives or use as hypoallergenic animal bedding, is gaining in popularity. The project will examine different nutrient rates of irrigation water to fertigate a willow plantation using ponded wastewater from a commercial mink ranching operation. A complementary field study and greenhouse study will be conducted at Dalhousie University to model nutrient uptake responses of two willow hybrids under intensive fertigation in a marginal and agricultural soil under greenhouse conditions.

希尔斯代尔毛皮农场是位于加拿大新斯科舍省的大型水貂生产牧场。农场产生每年约 120,000 张毛皮，年收入超过 900 万美元。重大挑战管理集约化商业畜牧业涉及到生产营养丰富的有机产品副产品，如粪便、用过的垫料和废弃饲料。副产品营养丰富，如果它们到达水源，就会引起环境问题、生产系统的巨大处置成本以及损失如果不使用的话有机会。希尔斯代尔毛皮农场目前正在探索管理高营养的途径浓缩蓄水池中收集的地表径流水，并检查处理方法通过使用水作为肥料来开发额外的价值机会。短期轮作林使用柳树（Salix）生产生物质作为替代燃料或用于增值的种植园系统通过提取物或用作低过敏性动物垫料，越来越受欢迎。该项目将审查使用来自池塘的废水对柳树种植园施肥的灌溉水的不同营养率商业水貂牧场经营。补充实地研究和温室研究将在达尔豪西大学模拟了两个柳树杂交品种在强化灌溉施肥条件下的养分吸收反应温室条件下的边际土壤和农业土壤。
