Phosphorus And Nutrient Management

Researchers investigate the fate and transport of phosphorus and other nutrients within agricultural and environmental systems. Studies examine nutrient cycling in soils, surface water, and groundwater, employing field experiments, laboratory analyses, and computer modeling. Areas of focus include optimizing nutrient application for crop production, understanding nutrient loss pathways from agricultural lands, and assessing the impact of nutrient pollution on water quality and aquatic ecosystems. Research also addresses the development and evaluation of best management practices to mitigate nutrient runoff and eutrophication.

This work directly addresses the needs of Arkansas's significant agricultural sector, particularly in rice and poultry production, by seeking to improve nutrient use efficiency and reduce environmental impacts. Managing nutrient levels is crucial for protecting the state's water resources, including the Mississippi River Delta and the Ozark Highlands, which are vital for drinking water, recreation, and biodiversity. Research contributes to sustainable agricultural practices that support the state's economy while safeguarding its natural heritage.

This research area draws on expertise from soil science, agronomy, environmental science, hydrology, and ecology. Engagement spans multiple institutions across Arkansas, fostering collaboration on critical nutrient management challenges.
