Impact of Manure Management Practices on the Environmental Fate of Antibiotics in Manure-Applied Fields
… for the first time that using the manure soil subsurface injection method, especially during spring application season due to moist soil, applying manure at least 3 days before a subsequent rainfall, and using composted manure, can significantly reduce the quantity of antibiotic loss with …

Modeling & Optimization of CO2-Mixture Frost Growth as a Carbon Capture Process & Integration with Sequestration
… surface-level cryogenic carbon capture with subsurface geological sequestration. The first part of the study advances understanding of CO2 frost growth and densification during cryogenic desublimation. A machine-learning framework, trained on an extensive literature-based data set, predicts …

Impact of Manure Land Management Practices on Manure Borne Antibiotic Resistant Elements (AREs) in Agroecosystems
… in the U.S. has reduced or stopped, making subsurface injection of manure a promising option when compared to surface application. Our research compared manure application methods, manure application seasons, cropping system, and manure-rainfall time gaps to gauge the impact on AREs in the …

The Occurrence and Fate of Steroid Hormones from Manure Amended Agriculture Fields
… slurry applied portion. New technologies for the subsurface application of poultry litter show promise as a tool to reduce the transportation of environmental hormones in surface runoff. Once adequate sampling protocols were established; it was determined that subsurface injection of both dairy …

Effects of Manure Injection on Transport and Transformation of Nutrient and Antibiotics
… such as the Chesapeake Bay watershed. Manure injection is a new technology that incorporates manure into the soil with minimal disturbance, and management strategies that reduce manure loss from agricultural fields could prevent the transport of nutrients and antibiotics to sensitive …

Nitrogen dynamics and biological response to dairy manure application
… is incompatible with no-till agriculture. Subsurface manure injection is a no-till compatible alternative application method which addresses these concerns, but likely changes the dynamics of nutrient cycling. Comparison of the two application methods has yielded mixed results and warrants …
