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 …
