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.********

我们建议开发一种经济有效的工业规模的灰分残留改良剂，并评价其对农业土壤的环境影响。木屑、树皮和木纤维的组合，通常被称为猪燃料，在生物质发电厂燃烧，以产生电力和处理蒸汽。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，这对公司来说是一笔巨大的成本。然而，将灰烬用作肥料将为农田提供大量的植物可用养分，并防止营养丰富的副产品被储存在垃圾填埋场。路易斯安那-太平洋加拿大有限公司、KRL解决方案有限公司和汤普森·里弗斯大学的研究人员已经建立了合作伙伴关系，以开发一种大规模、环境友好的火山灰残留物化学改进剂。修订后，灰渣将按行业相关规模应用于农业领域，养分和重金属含量将通过土壤采样、通过基于无人机系统(UAS)的传感器确定作物健康/植物压力以及对产生的植被进行饲草分析来监测。我们建立的经过工业副产品改良的农田土壤养分含量与基于UAS的作物健康监测之间的相关性将导致开发一种新的方法来评估工业环境中副产品再利用的环境影响。路易斯安那州-太平洋加拿大有限公司将对其产生的灰渣进行环保和经济友好的新用途，从而减少垃圾填埋场中储存的灰渣数量。KRL解决方案有限公司将把这种新的农业和环境无害的应用方法纳入他们目前的商业模式，以便向全国各地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采用将降低农业生产者的化肥成本，显著减少最终进入垃圾填埋场的灰渣残留量，并为评估副产品分配对农业土地的环境影响提供一种新的、基于UAS的方法。
