Estimation of Production and Best Management Practice Cost in a Crop Based Watershed in Arkansas

In the Mississippi Delta, vast acreages of rice and soybean employ high levels of fertilizers, pesticides and water for production. Without proper management, use of these inputs could lead to sediment and nutrient movement off the farm and into nearby rivers and streams. Rice, soybean and cotton producers in the Arkansas Delta region might consider the establishment of best management practices to help overcome water pollution in the region. However, in selecting these practices, farmers deal with increasing costs of production that diminish the adoption of expensive practices.
The goal of this project was to develop a water quality-water conservation decision support system based on linkages among water conservation, agricultural production, water quality, and watershed-scale ecosystem integrity. This goal was accomplished by fulfilling two objectives:
  1. Create an interactive illustration of farm crop budgets including BMPs costs for rice, soybean and cotton in the Languille River watershed.
  2. Identify the efficient set of BMPs in terms of its effectiveness to reduce TP and its relative costs to rice and soybean producers.
