Abstract: Grassland modeling requires knowledge of rate-limiting processes to accurately simulate biomass growth. Increased understanding of factors controlling grass biomass production will help define productivity of different grassland communities. Thus, limitations due to stress or due to canopy architecture and leaf area can be better understood. As part of a project to model grasslands, we measured several aspects of growth of Alamo switchgrass, eastern gamagrass, and two other common warm-season grasses (sideoats grama and big bluestem). Traits including leaf area index, aboveground biomass, and light interception were measured several times during the three growing seasons on a deep, Houston black clay soil near Temple, TX. We also measured root mass and soil carbon with soil cores at the end of two growing seasons. These measurements were all designed to quantify leaf area production and biomass growth to assist in computer simulation of these grasses in diverse environments.
