Root distribution characteristics of three turfgrasses and their impact on soil nutrient content

Abstract

Abstract: Root and soil samples were collected from mature Festuca arundinacea, Lolium perenne and Poa pratensis. The root depth of F. arundinacea had reached 1.8 m, and the root biomass of F. arundinacea was 3.1 and 3.0 times the weight of L. perenne and P. pratensis respectively. There were significant influences of root distribution characteristics of turfgrasses on soil nutrient content. The differences in soil nitrate between turfgrasses were not significant in the 0-40 cm layer, but were significant in the 40-100 cm layer, with a ranking of P. pratensis＞L. perenne＞F. arundinacea. Soil available P decreased greatly as soil depth increased, and the differences between turfgrasses were significant in the 0-60 cm layer with rankings of P. pratensis＞L. perenne＞F. arundinacea. Soil available K was highest at 0-20 cm and showed no decrease in the 20-100 cm layer.
