La ferme avicole Paul Richard et fis inc established their family farm in 1954 in Rivière-Héva, Quebec and developed a profitable egg production operation that employs 20 full-time, year-round employees and supplies wholesalers and groceries throughout northern Québec and northern Ontario. The farm's vision is to increase farming and rural economic development in their region, which is a challenge given the northern climate and soil conditions. The company-specific problem is how to sustain soil fertility and get good yields of high-quality cereal and oilseed crops to feed their laying hens, rather than trucking corn and soybean from southern Quebec. For ecological and economic reasons, they would prefer to sustain the soil fertility using local fertilizing materials, rather than purchasing expensive inorganic fertilizers that must be transported from the south. Pelletized hen manure, a product of poultry farms, is a valuable fertilizer. However, its contribution to soil nitrogen fertility in heavy clay soils for cereal production during a short growing season is very poorly understood. Valorizing pelletized hen manure as a nitrogen fertilizer for northern agriculture requires information on the susceptibility of the hen manure to nitrogen volatilization, in the barn and in the field, as well as the pattern of nitrogen release after pelletized hen manure is applied to the field. Laboratory and in-field testing that can be done by engaging with McGill are the scientific basis for nitrogen release from pelletized hen manure in current and future growing seasons, by controlled incubations, analysis of the resin-extractable ammonium and nitrate concentrations in soil, and evaluation of nitrogen uptake in barley. The farm will benefit from better knowledge of the nitrogen fertilizer value of pelletized hen manure, which is applied to 650 acres of their own farmland. La ferme avicole Paul Richard et fis inc has more pelletized hen manure than they can use, and this Engage project will give them the necessary information to market hen manure as a 'higher-value fertilizer', for sale to agricultural producers and industry (e.g., for afforestation and mine land reclamation) in the regions of Abitibi-Témiscamingue, Chibougamau, northern Québec and northern Ontario.

La ferme avicole Paul Richard et fis inc于1954年在魁北克的Rivière-Héva建立了他们的家庭农场， 开发了一个有利可图的鸡蛋生产业务，雇用20名全职，全年员工和供应 批发商和杂货店遍布北方魁北克和北方安大略。农场的愿景是增加 农业和农村经济发展，这是一个挑战，因为北方的气候， 土壤条件公司面临的具体问题是如何保持土壤肥力， 高质量的谷物和油籽作物来喂养他们的蛋鸡，而不是用卡车从 魁北克南部。基于生态和经济的理由，他们宁愿利用当地的土地来维持土壤肥力， 肥料，而不是购买昂贵的无机肥料，必须从 南家禽养殖场生产的颗粒状鸡粪是一种有价值的肥料。然而，其贡献 在较短的生长季节，重粘土壤的氮素肥力很差 明白将颗粒状鸡粪作为北方农业的氮肥， 关于鸡舍和田间鸡粪对氮挥发敏感性的信息， 以及颗粒化鸡粪施入田间后氮素释放规律。实验室和现场 可以通过与麦吉尔合作进行的测试是颗粒状氮释放的科学依据， 当前和未来生长季节的鸡粪，通过控制培养，分析树脂提取物 土壤中的铵和硝酸盐浓度，以及大麦的氮吸收评估。农场将受益 从更好地了解颗粒状鸡粪的氮肥价值，这是适用于650英亩， 他们自己的农田。La ferme avicole Paul Richard et fis inc有更多的颗粒状鸡粪， 使用，这个参与项目将为他们提供必要的信息，以市场鸡粪作为一个'高价值 肥料“，用于销售给农业生产者和工业（例如，造林和矿山土地复垦）， Abitibi-Témiscamingue、奇布加毛、北方魁北克和北方安大略地区。
