Historic manure stockpiled (active from 1935 through 2018) in a repository mound approximately 15 m high with a 31,415.93 m footprint was sampled from various depths at six locations in an environmental assessment framework. The manure samples were analyzed for nutrient content to investigate potential application as a soil amendment to local fields in combination with biowaste disposal regulations. Results indicate that manure can be used as a soil amendment; however, different crops and land conditions require specific nutrients, and application must be determined accordingly. Likewise, the manure analysis did not indicate any negative issues that would disallow land application as a disposal option. In addition to limiting environmental soil boring into the manure repository, two-dimensional geophysical electrical resistivity imaging was performed to characterize and quantify the deposited manure. Based on those efforts, the material volume within the site's manure repository was calculated to be 611,942.354 cubic meters (m). Finally, based on the geophysical results and the historical information about the manure's deposited volume in the study area, an estimation of the released landfill gases and its expected produced energy is presented.
在一个环境评估框架中，从一个占地面积为31415.93平方米、高约15米的储存堆中采集了1935年至2018年期间储存的历史粪便样本，该储存堆位于六个地点的不同深度。对粪便样本进行了养分含量分析，以结合生物废物处理规定，研究其作为土壤改良剂应用于当地农田的潜力。结果表明，粪便可以用作土壤改良剂；然而，不同的作物和土地条件需要特定的养分，必须据此确定施用方法。同样，粪便分析也未表明存在任何会禁止将其用于土地处置的负面问题。除了限制对粪便储存库进行环境土壤钻探外，还进行了二维地球物理电阻率成像，以表征和量化堆积的粪便。基于这些工作，计算出该场地粪便储存库内的物料体积为611942.354立方米（m³）。最后，根据地球物理结果和研究区域内粪便堆积量的历史信息，对释放的填埋气体及其预期产生的能量进行了估算。
