We explore the value of soil test, topographical, and remote sensing information for guiding variable rate fertilizer applications in corn. Results suggest combining topographical and remote sensing information is more valuable than conventional soil tests. Considered separately, topographical...

We develop a dynamic bioeconomic model of temporally optimal dynamic refuge recommendations for resistance management when a backstop technology arrives at a known date. The impact of the characteristics of the backstop on the use of the current technology, and the difference between static and...

A bioeconomic model is developed to evaluate the tradeoff between the risk of resistance and increased productivity when refuge is planted in conjunction with transgenic pesticidal corn. The model is used to evaluate controversial refuge recommendations when producers are allowed to treat refuge...

Studies on the optimal use of pesticides, their disposal, and effects are presented. Papers include: Financing the Disposal of Unwanted Agricultural Pesticides, Lewell F. Gunter and Terence Centner, University of Georgia. Determinants of Pesticide Registration for Food Crops, Claude Courbois,...

The total expected cost of sequestering carbon in agricultural soils is estimated under a possible EQIP program offering a per-acre subsidy to adopt conservation tillage and a carbon credit program where producers can sell their carbon credit in an external market. Both programs are compared to...

The effect of marketing uncertainty due to consumer opposition over genetically modified (GM) grain is modeled in the context of a producer's decision to plant GM. The model shows that a tendency to plant less GM acreage and obtain premium prices for Non-GM grain is tempered by increased price risk.

Given the importance of adopting weed resistance management BMPs, it is important to develop methods to compare BMP adoption among farms and to identify factors that affect BMP adoption. Because of the relatively large number of BMPs and interactions among them, a composite index that integrates...
