Researchers evaluate the profitability of planting flood-tolerant crops in flood plains relative to traditional row crops under different assumptions concerning flood frequency and the level of government crop subsidy. Short rotation woody crops and herbaceous energy crops are evaluated for two...

To evaluate the impact of conservation policies on soil organic carbon in agricultural soils, the authors link information from the 1992 National Resources Inventory (NRI) database and the extensive physical data on soils and climate from the SOILS5 database. These data serve as input for a...

In order to prolong the efficacy of Bt, the Environmental Protection Agency has imposed mandatory refuge requirements for Bt crops. Growers, however, have no economic incentive to comply with requirements because, on average, refuge crops are riskier and less productive. The authors evaluate...

Mitchell describes a maximum likelihood method using historical weather data to estimate a parametric model of daily precipitation and maximum and minimum air temperatures. Historical weather data from Brookings, SD, and Boone, IA, are used to create the model. Mitchell describes the process of...

The Resource and Environmental Policy (REP) Division of CARD needed accurate cost of production system (COPS) budgets to integrate into its existing environmental modeling system. Cost and Returns Estimator (CARE) crop budgets were reorganized and modified to create a unique COPS budget for each...

The Central Nebraska Basin (CNB) is the site of intensive agricultural activity, in part because of the good irrigation supplies provided by the Middle Platte alluvial aquifer system. In this paper, the authors describe the integrated modeling system that addresses the economic and environmental...

Using a published single-season model of adult population dynamics and data from field experiments, Mitchell and Riedell develop a complete life cycle model for northern corn rootworm. To develop the life cycle model, Mitchell and Riedell use temperature-dependent development and age-dependent...
