Development of an industrial scale ash residual amendment, and application methodology and analysis of its environmental impact on agriculture soils

我们建议开发一种具有成本效益的工业规模的灰残留修正剂，并评估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Hog燃料，在生物质发电厂燃烧以发电和加工蒸汽。产生的副产品灰分残留物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，利用灰作为肥料将为农业用地提供大量的植物可用营养素，并防止富含营养素的副产品储存在垃圾填埋场中。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河流大学的研究人员已经成立，以开发一种大规模的，环保的，对灰烬残留物的化学修正。根据这一修正案，灰残留物将以工业相关规模应用于农田，营养和重金属含量将通过土壤采样、基于无人机系统（UAS）的传感器的作物健康/植被压力测定以及对所产生植被的饲料分析进行监测。我们建立的相关性，由工业副产品和UAS为基础的作物健康监测改性的农田土壤养分含量将导致开发一种新的方法，评估在工业环境中的副产品再利用的环境影响。Louisiana-Pacific Canada Ltd.将对其产生的灰烬残渣进行新的环境和经济友好用途，从而减少垃圾填埋场中储存的灰烬量。KRL Solutions Ltd.将把这种新的农艺学和环保应用方法纳入其当前的商业模式，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者的肥料成本，显着减少最终进入垃圾填埋场的灰烬残留物的数量，并提供一种新颖的基于UAS的方法来评估副产品分布对农业土地的环境影响。

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.
