Summary of Methods: Authors evaluate the effects of management intensity, defined in terms of N fertilization and stocking rate, on litter mass, deposition rate, and chemical composition in continuously stocked 'Pensacola' bahiagrass (Paspalum notatum) pastures in Florida. Treatments were three management treatments: low, moderate, and high. Greater management intensity resulted in less litter mass on the pasture early in the growing season and more litter mass later in the season. Rate of litter decomposition was generally greatest for high treatment. Increasing management intensity from low to high resulted in greater litter N concentrations and lesser C:N, C:P, and lignin:N ratios. More intensive pasture management was associated with greater litter deposition rate and litter quality than less intensive management, suggesting a larger nutrient contribution from litter in intensively managed swards.
