Large quantities of manure and organic wastes produced from farm feedlots and other sources pose logistic (such as disposal, transportation cost if land-filled and social acceptability) as well as environmental problems, such as odor, greenhouse gas production and nutrient loss. Biogas production and biodigestion of manure followed by composting provides an opportunity for environmental friendly application of stabilized manure (or biofertilizers) for crop production, improvement of soil properties, and reduction of greenhouse gas emissions. This research will test the economic (crop productivity) and environmental benefits (improvement of soil properties and reduction of greenhouse gas emissions) of organic fertilizer applications in agricultural production by comparing the applications of inorganic fertilizers, stabilized manure, biofertilizer, and biofertilizer combined with blended biochar, using a rigorously designed experiment. This research will also evaluate the effects of stabilized manure and biofertilizer applications on soil physical, chemical and biological activities. We aim to improve our understanding of the benefits of the application of stabilized manure and biofertilizers and enable the promotion of biofertilizer application in agricultural production systems as an alternative to disposing manure in landfills. This would benefit companies in marketing the product and in developing techniques for proper application of organic fertilizers in the field.

农场饲养场和其他来源产生的大量粪肥和有机废物造成物流问题（如处置、填埋的运输成本和社会可接受性）以及环境问题，如气味、温室气体产生和养分损失。沼气生产和粪便的生物消化，然后进行堆肥，为稳定的粪便（或生物肥料）用于作物生产、改善土壤特性和减少温室气体排放提供了环境友好型应用的机会。本研究将通过严格设计的实验，比较无机肥料、稳定化粪肥、生物肥料和生物肥料与混合生物炭的应用，测试有机肥料在农业生产中的经济效益（作物生产力）和环境效益（改善土壤性质和减少温室气体排放）。这项研究还将评估施用稳定粪肥和生物肥料对土壤物理、化学和生物活性的影响。我们的目标是提高我们对施用稳定粪肥和生物肥料的好处的理解，并促进在农业生产系统中应用生物肥料，作为在垃圾填埋场处理粪肥的替代方案。这将有利于公司销售产品和开发在田间适当施用有机肥料的技术。
