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灰渣残留改良剂，并评估其对农业土壤的环境影响。木片、树皮和木纤维的组合，通常被称为生猪燃料，在生物质发电厂中燃烧以发电和处理蒸汽。产生的副产品灰渣传统上储存在现场垃圾填埋场或运输到永久垃圾填埋场，这给公司带来了巨大的成本。然而，利用灰烬作为肥料将为农田提供大量植物可用的养分，并防止将富含养分的副产品储存在垃圾填埋场中。 Louisiana-Pacific Canada Ltd.、KRL Solutions Ltd. 和 Thompson Rivers 大学的研究人员已建立合作伙伴关系，开发大规模、环保的灰烬残留化学改良剂。根据此次修订，灰烬残留物将按行业相关规模应用于农田，养分和重金属含量将通过土壤采样进行监测，通过基于无人机系统（UAS）的传感器确定作物健康/植物胁迫以及对所得植被的饲料分析。我们在工业副产品改良的农田土壤养分含量与基于无人机的作物健康监测之间建立的相关性将导致开发一种评估工业环境中副产品再利用对环境影响的新方法。路易斯安那-太平洋加拿大有限公司将对其产生的灰渣进行新的环保且经济的利用，从而减少垃圾填埋场中储存的灰烬量。 KRL Solutions Ltd. 将把这种新的农艺和环境友好型应用方法纳入其当前的业务模式中，以便为全国类似的生物质燃料发电厂提供这项服务。该项目所产生的技术的采用将降低农业生产者的化肥成本，显着减少最终进入垃圾填埋场的灰烬残留量，并提供一种基于无人机系统的新颖方法来评估副产品分配对农田的环境影响。
