Assessing Economic and Environmental Impacts of Ethanol Production on Fertilizer Use in Corn Production
Provedor de dados: 31
Autores: Nehring,   Richard F.; Vialou,   Alexandre; Erickson,   Kenneth W.; Sandretto,   Carmen L.
The share of corn used in ethanol production has been growing rapidly. USDA predicts that more than 30 percent of the corn crop will be used for ethanol production in 2009/2010. Expanded corn acreage contributes to the application of more fertilizer and is likely to introduce a larger volume of nutrients into the environment. This study found that an increase in ethanol production is consistent with a significant increase in quality-adjusted fertilizer use in selected corn states.

Impact of GE Crop Adoption on Quality-Adjusted Herbicide Use in U.S. Corn Production
Provedor de dados: 31
Autores: Nehring,   Richard F.; Martin,   Andrew; Fernandez-Cornejo,   Jorge; Hallahan,   Charles B.; Vialou,   Alexandre; Wechsler,   Seth James; Grube,   Arthur.
This paper presents findings on the use of HT corn and quality-adjusted herbicide use for 12 key corn producing states using a panel data set for 1986-2008. Our preliminary findings indicate an insignificant impact of HT corn on herbicide use, conditioning or accounting for HT corn with other important drivers of corn herbicide use: HT soy, corn output price, glyphoste price, nonherbicide glyponsate price, and percentage of continuous corn and low-till corn. However, we find a positive and significant impact of HT corn on herbicide use in selected states, using regional interaction terms.  We use econometric techniques to avoid spurious regression results. Other preliminary runs indicated that the results hold when running the US and regional interactions...
