Abstract/Contents:"The experimental site, which was a soccer pitch, had an initial turfgrass composition: Lolium perenne 45 %, Agrostis tenuis 35 %, Poa annua 15 % and broad leaved weeds 5 %. Over the experimental period of 22 weeks, diplicate [duplicate] plots of 10 m2 received one of three fertiliser levels and were clipped every 5 days at 1.3 cm, 2.5 cm or 2.5 cm height. The overall fertiliser levels were respectively in kg/ha of N, P205, K20: 0, 50, 44; 88, 75, 75; 313, 300, 300. One quarter of the overall fertiliser was applied at 5 week intervals. All clippings were removed and analysed for N, P and K. At the end of the experiment the turfgrass composition was analysed and tiller density determind [determined]. The dry matter content of clippings decreased with increase in nitrogen level at each height of cut and decreased with lower height of cut at each nitrogen level. The overall yield of clippings ranged between 1600 kg/ha and 6300 kg/ha. Despite the range in level and ratio of applied fertiliser nutrients, the ratio of N: P2O[P2O5]: K2O in the clippings remained remarkably constant. The overall mean ratio was 3.7: 1.0: 3.2. The treatments brought about a considerable change in turfgrass composition. Most apparent was a progressive increase in P. annua with decrease in cutting height and increase in nitrogen fertiliser. The increase in P. annua was chiefly at the expense of bent."
