Residential lawn management practices and the impact on the urban nitrogen balance.
Law, Neely, Lawrence E. Band, J.M. Grove
To address how social behavior may affect nutrient budgets in urban watersheds, results of a household survey to determine the nitrogen input from lawn care practices is presented. Survey results indicate that nitrogen input from lawn care practices is a dominant source of nitrogen in the nitrogen budget, but loadings are spatially and temporally variable. Statistical analyses of lawn care management practices and soil samples suggest that environmental and social demographic characteristics affect nitrogen input to lawns.
