• W2971328814 abstract "For agriculturalsoils to be perpetually productive, farmers must maintain and improve thephysical, chemical, and biological properties of the soil. The loss of soil to erosion is a major challengeto soil health, contributing to farmland loss and declines in productivity. Thisis a long-term problem for agriculture because there is a limited amount oftopsoil available. Another costly loss happens when residual nitrogen is lost to leaching orcarried away in runoff. This is a particular problem in the fall and wintermonths when fields lie fallow, and there are no plants to take up excessnitrogen. Losing nitrogen is a problem for both the nutrient content of thesoil as well as a serious concern in terms of water contamination. Cover crops provide away to at least partially address each of these and many other agronomic andsoil health issues. Although there hasbeen a steady increase in cover crop use, adoption has been relatively slow. Thisis likely due to a lack of economic information and understanding of theassociated risk. To address this problem, field level data was gathered from farmersacross central and northeastern Indiana. The data included information on cashcrop yield, cover crops grown, fertilizer use, among many other variables. Thesample was trimmed based on the estimated propensity to cover crop, in order toreduce selection bias. Using this data, the effect of cover crops on the meanand variation of the subsequent cash crop yield was estimated using regressionanalysis. This information was combined in a stochastic analysis of a farm enterprisebudget. The effects of cover crops on farm finance and risk were evaluated. Thesefinal analyses provide agricultural producers with more information to make informeddecisions regarding the adoption of cover crops. The information may alsoprovide insight to policy makers, who may wish to understand more completelythe private economics of cover crops. The results indicatedthat cover crops have the ability to provide economic benefits when grown priorto corn in our study region. These include increased yield, reduced need fornitrogen fertilizer, and increased temporal yield stability. These benefitstranslate into higher revenue from the sale of the grain, lower input costs,and lower risk and uncertainty. However, the results for soybeans showed covercrops had a negative, albeit statistically insignificant, effect on desirablemeasures. This led to lower projected revenue, higher projected costs, andincreased expected risk. Even so, the average corn-soybean contribution marginwith cover crops was nearly equal to the baseline scenario. Furthermore, theanalysis of risk showed that the corn-soybean two-year average would bepreferred by farmers with moderate to high risk aversion. The differencebetween the effect of cover crops in corn and soybeans may be due todifferences in the crop’s inherent nitrogen needs and the difficulty of covercrop establishment after corn in the region." @default.
