We propose to develop a cost-effective industrial-scale ash residual amendment and evaluate its environmental impact on agricultural soils. Combination of wood chips, bark and wood fiber, commonly known as Hog fuel, is burned in biomass-fired power plants to generate electricity and process steam. The by-product ash residuals that are produced, are traditionally stored in an onsite landfill or transported to a permanent landfill at a significant cost to the company. However, utilization of the ash as a fertilizer would provide significant amounts of plant useable nutrients to agricultural lands and prevent a nutrient rich by-product from being stored in a landfill. A partnership between Louisiana-Pacific Canada Ltd., KRL Solutions Ltd. and researchers at Thompson Rivers University has been established to develop a large scale, environmentally friendly, chemical amendment of the ash residuals. Following this amendment, the ash residuals will be applied to agricultural fields on an industry relevant scale and nutrient and heavy metal content will be monitored by soil sampling, crop health/vegetative stress determination by way of Unmanned Aerial Systems (UAS) based sensors and forage analysis of the resulting vegetation. The correlation that we establish between soil nutrient content of agricultural fields modified by an industrial by-product and UAS based crop health monitoring will lead to the development of a novel method of assessing the environmental impact of by-product reuse in an industrial setting. Louisiana-Pacific Canada Ltd. will have a new environmentally and economically friendly use for the ash residuals that it produces, thus reducing the amount of ash stored in landfills. KRL Solutions Ltd. will incorporate this new agronomically and environmentally sound application methodology into their current business model in order to provide this service to similar biomass-fueled power plants throughout the country. Adaption of the technology generated from this project would reduce fertilizer costs for agricultural producers, significantly decrease the amount of ash residuals that end up in landfills and provide a novel, UAS based methodology for assessing the environmental impact of by-product distribution on agricultural lands.

我们建议开发一种具有成本效益的工业规模的灰分剩余修正案，并评估其对农业土壤的环境影响。木屑，树皮和木纤维（通常称为猪燃料）的结合在生物质发电厂中燃烧，以产生电力和加工蒸汽。产生的副产品灰分残留物传统上存储在现场垃圾填埋场中或将其运送到永久垃圾填埋场，以巨大的费用。但是，将灰分作为肥料的利用将为农业土地提供大量植物可用的养分，并防止富含营养的副产品存储在垃圾填埋场中。已建立了路易斯安那 - 太平洋加拿大有限公司与汤普森河大学的研究人员之间的合作伙伴关系，以开发大规模的，环保的，化学友好的化学修正案。经过此修订后，将通过土壤采样，基于无人体空中系统（UAS）的传感器（UAS）传感器（UAS）的方式来监测烟灰残留物，并以行业相关规模和养分和重金属含量来应用于农业领域。我们在由工业副产品和基于UAS的农作物健康监测修饰的农业领域的土壤养分含量之间建立的相关性将导致开发一种新的方法，以评估工业环境中副产品再利用的环境影响。路易斯安那 - 太平洋加拿大有限公司将在其产生的灰烬残留物上有一种新的环境和经济友好的用途，从而减少了垃圾填埋场中存储的灰分数量。 KRL Solutions Ltd.将在其当前的业务模型中纳入这种新的农业和环境应用方法，以便为全国类似的生物质燃料发电厂提供这项服务。该项目产生的技术的适应将降低农业生产商的肥料成本，大大减少了最终在垃圾填埋场中的灰分残留量，并提供了一种基于UAS的新方法，以评估副产品分布对农业用地的环境影响。
