Abstract/Contents:"In order to assess nitrogen and water utilization three constructions were set up in lysimeters, consisting of a drainage layer construction (treatments 1 & 2), a construction in which the soil underlying the rootzone was first of all ameliorated with sand (treatments 3 & 4), and a construction with drainage slits (treatments 5 & 6). Each of these constructions was topped with either a rootzone mixture without topsoil but a graded particle size distribution (treatments 1, 3 & 5) or one containing 15% sandy loam topsoil (treatments 2, 4 & 6). Fertilizer application and other maintenance operations were identical for all treatments. The main results were as follows: In the first winter there was winter damage on the Lolium perenne, which was reduced about 20-30% more on the soil-less rootzone than on the other. Sward appearance was somewhat worse on the rootzone with soil. The two constructions with rootzones on soil had better sward appearance than the one with the drainage layer. In sward density under artificial wear treatment there were no clear differences between the constructions, but the sward density was somewhat greater in the treatments with the soil-less rootzone. As regards the relationship of soil and sward growth increments, soil in the rootzone was associated with less growth, ie there was more growth on the soil-less rootzone, whereas among the different constructions the presence of soil under the rootzone increased growth. Clippings biomass showed a similar pattern. Thatch thickness and above-ground biomass showed, after four growth seasons, somewhat lower values for the rootzone with soil, and also in the two constructions with soil under the rootzone. In general one can infer from the results a reduced wear tolerance of the sward, and some reduction in N utilization, in the compaction-susceptible rootzone with soil. Soil under the rootzone, on the other hand, contributed to an increased N supply and reduced somewhat the amount of thatch."
