My current research, which I began in 2006, focuses on medicinal crops as potential new cash crops for Alabama. The goal is to identify species that are adapted to Alabama with market potential and determine cropping practices and varieties that enhance the quantity and yield of bioactive compounds. Current species of interest include American skullcap (Scutellaria lateriflora), Baikal skullcap (Scutellaria baicalensis), turmeric (Curcuma longa) and Astragalus root (Astragalus membranaceus). Prior research focused on alley cropping, an agroforestry system in which annual crops are grown between rows of closely-planted trees. My research addresses issues related to application of the technology under different tropical and subtropical environments. In Alabama, we assessed alley cropping as a cost-effective alternative to conventional terraces for soil and water conservation on sloping land, measuring runoff, sediment and nutrient losses and crop yield.
