Soil nitrogen, active carbon, corn, and small grain response to manure injection
Manure injection is an alternative manure application method that places manure in subsurface bands rather than spreading it evenly across the soil surface as done with the typical broadcasting method. The reduced exposure of manure to air under injection can lead to greater N retention when …

Effects of Manure Injection on Transport and Transformation of Nutrient and Antibiotics
Overapplication of manure in sensitive watersheds is an issue of increasing environmental concern due to increased nutrient loading and antibiotic release into aquatic environments. Manure is typically surface applied, leaving nutrients and antibiotics vulnerable to loss at the soil surface. …

Nitrogen dynamics and biological response to dairy manure application
Animal manures are land applied in agronomic systems to supply essential crop nutrients and decrease dependency on chemical fertilizers. Liquid manures are traditionally surface broadcast to fields and sometimes incorporated to reduce odor and nutrient losses; however, incorporation is incompatible …

Fate and transport of antibiotic resistant bacteria and resistance genes in artificially drained agricultural fields receiving swine manure application
… in their excrement. Application of swine manure to agricultural fields as fertilizer creates a pathway for antibiotic resistant bacteria and their associated resistance genes to enter the environment. This study monitored enterococci, tylosin resistant enterococci and four genes known to …
