Nitrogen dynamics and biological response to dairy manure application
… fertilizers. Liquid manures are traditionally surface broadcast to fields and sometimes incorporated to reduce odor and nutrient losses; however, incorporation is incompatible with no-till agriculture. Subsurface manure injection is a no-till compatible alternative application method which …

Enhanced efficiency phosphorus application for corn
… of tillage/fertilizer placement [no-till (NT)/surface broadcast or strip-till (ST)/deep banding], monoammonium phosphate rate [0, half the recommended rate, and the recommended rate], and the presence and absence of two enhanced phosphorus efficiency products [Avail[copyright] (Specialty …

Nitrogen and phosphorus fertilization for efficient corn production in Virginia
Traditional com fertilization methods of broadcasting N fertilizer, and applying P fertilizer to soils testing high to very high in plant-available P, can be inefficent. Experiments were conducted at several locations in Virginia to evaluate if band applications of N fertilizer are more efficient …

Quantifying the agronomic and water quality tradeoffs of fertilizer management with multiobjective evolutionary algorithms
… not only maximize profit for injection and surface broadcast but also reduce outcome sensitivity to the placement method and offer the best compromise between pro fit and drainage nitrate loads. Although testing different calibration parameters could further support these results and re fine …

Impact of Manure Land Management Practices on Manure Borne Antibiotic Resistant Elements (AREs) in Agroecosystems
… manure application techniques can reduce surface runoff of other contaminants such as excess N and P, pesticides, and hormones, that can impact water quality. Conventional tillage practices in the U.S. has reduced or stopped, making subsurface injection of manure a promising option when …
