Non-point source pollution created by agriculture is one of the major issues of intensive production. Recent studies indicate that the eutrophication from agricultural non-point source pollution, especially from phosphorus, is of growing concern. The

This research introduces a simple variation of distributed delay algorithms to solve some relevant problems in simulation of plant development. Cotton was used as a case study. An energy-based model of cotton plant growth was expanded to account for

The growth of the poultry industry in Arkansas has exploded in the past decade. As a result, approximately 1.5 million tons of litter are produced every year. Concerns about possible contamination of ground and surface water from land applications of
