To investigate the seasonal uptake of nutrients by turf grass on an area basis is important for two reasons: (1) to maintain good turf condition with appropriate fertilizer management; and (2) to prevent environmental pollution with excess nitrate and acidification of soils by excess application of fertilizers. There have been few studies about this topic because of difficulties in measuring the uptake rate of nutrients by turf grass per area, which fluctuate with species of grass, and a growing number of confounding management practices such as cutting interval and the amount and interval of fertilizer application, and the affects of seasonality. We investigated the uptake of three major nutrients (N, P2O5, K2O) by turf grass (mixed planting of Bermuda grass with Kentucky bluegrass) at one week intervals during May to end of September, which corresponds to the growing season in relation to the management of a turf ground in Ikuta Campus, Meiji university.
