Abstract/Contents:"A field study to compare the effects of various fertilization schemes on turf quality of Poa pratensis and nitrate dynamics in the soil was conducted in Beijing between May 2001 and November 2002. The results indicated that fast release fertilizer provided the greater initial response, while slow release fertilizer gave the outstanding residual characteristics based on color ratings. Fertilization in summer sharpened the injury of brown patch disease, whereas the least injury was observed for Diammonium-phosphate treatment. In addition, the reduced tiller number was found because of the brown patch. The turfs fertilized with slow release fertilizer at 4 applications and 'Urea+Diammonium-phosphate' abtained [obtained] best uniformity for the entire growing seasons. The turf fertilized with slow-release fertilizer had a slow fluctuation of growth rate. Fertilization at 2 applications in fall got more underground biomass than that as 1 application. Soil NO3--N concentration was mostly effected by fertilization and the NO3--N concentrations in soils of 0-20 cm were associated with different patterns of nutrition releasing."
