Obj 1: Enhance the benefits of using animal manure as means of improving soil productivity for longterm production systems. 1.1 Improve soil health/quality through a longterm mngmnt practice involving animal manure, cover crop, & crop rotation. 1.2 Determine if poultry litter application timing (fall/spring) & cover crop (cover crop/no cover crop) affects on corn N use efficiency & yield. 1.3 Develop improved models for describing phosphorus cycling in soils amended with animal manure. 1.4 Develop an energy-efficient & cost-effective method of capturing ammonia from animal facilities & subsequent usage as fertilizer. 1.5 Evaluate poultry litter application on the incidence of Clostridium botulinum in haylage forage harvest systems & stand persistence. 1.6 Improve sustainability through a management strategy using cover crop grazing & animal manure to improve soil quality & fertility while increasing grain & livestock production. 1.7 Combining a multi-proxy investigation of agricultural contaminant transport in Karst groundwater systems & informal education to improve stewardship & best management practices. Obj 2: Develop strategies for managing the survival & transport of antibiotics, pathogens & indicator species through agroecosystems. 2.1 Determine whether biochar-amended sand filters are an effective management practice for removing pathogenic & indicator microorganisms from tile drainage waters. 2.2 Characterize persistence and transmission of antibiotics, antibiotic resistance (AR) genes, AR mobile genetic elements and AR bacteria through agro-ecosystems. 2.3 Determine factors controlling adhesion & survival of manure-borne pathogens in manured soils & on crops & identify mitigation strategies. 2.4 Develop of methods for measuring antibiotics in agricultural samples & the correlation of the presence of antibiotic resistant bacteria. 2.5 Develop a strategy for rapid detection & deletion of antibiotic resistance genes using DNA-binding domain based nucleases. Obj 3: Assess gaseous & particulate matter emissions resulting from animal prod. facil. & manure application sites. 3.1 Develop methods for the determination of VOC that contribute to malodorous emissions from field applied manures & use these methods to compare emissions from different manure application methods to field crops. 3.2 Obtain field measurements of the temporal variability of gas & particulate matter emissions. 3.3 Determine the fate of atmospheric N and sulfur emissions from agricultural systems. 3.4 Measure & model the fates of VOCs, PM, & GHGs from agricultural systems. 3.5 Model the chemical partitioning of N compounds between gas & particulate phase. Obj 4: Improve production efficiency & emissions management of renewable bioenergy production systems using technologies such as anaerobic digesters. 4.1 Investigate biogas production and substrate utilization of poultry litter & use microaeration to improve biogas production. 4.2 Optimize anaerobic digestion of poultry wastes to reduce emissions & obtain bioenergy for sustainability. 4.3 Develop novel & cost-effective composite alginate filter materials to capture ammonia, GHG, odors from livestock prod. facil.
