We estimate the cost of offsets tied to reductions in the use of nitrogen on U.S. cornfields under the proposed …

Using ammonium based nitrogen fertilizers in crop production has been shown to acidify soils. Lime used to correct soil … pH is an important cost to producers. Recommendations of the optimal level of nitrogen to apply typically ignore the cost … of lime created by nitrogen fertilization. This study was aimed to estimate soil pH change in response to nitrogen and …

increases in nitrogen application (and potential runoffs). This result suggests that concerns about adverse environmental …

nutrient applications deteriorate groundwater (nitrogen) and surface water quality (nitrogen and/or phosphorus). Due to … differences in environmental and economic characteristics, adjacent regions may have differing objectives for nitrogen and …. As the prevailing regulatory tool for livestock production is the Nutrient Management Plan based on nitrogen standard …

could reduce nitrogen runoff. Energy costs may be reduced with adoption of reduced tillage technology, improved drying and …

Agricultural nitrogen losses are the major contributor to nitrogen loads in the Mississippi River, and consequently, to … reducing nitrogen losses. Of particular importance was the study's explicit focus on agricultural subsurface (tile) drainage …, which has been identified as the major pathway for agricultural nitrogen losses in the upper Midwest, and the use of …

illustrated that return to VRT and the viable range of spatial variability increased for higher corn and nitrogen prices. …
