| Abstract/Contents: | SUMMARY: "Two turf trials are reported in the paper, intended to compare different N fertilisers in respect of "compatibility" with the sward, long-term effects and the amount of nitrogen needed for good turf quality. In the first trial, 160, 200 and 240 kg ha-1 N were given in one application at the end of May. Of the three fertilisers tested, IBDU was the most "compatible", as can be seen from sward appearance scores and growth measurements. A combination of sulphate of ammonia and dicyandiamide (DCD) resulted sometimes in temporary scorching of the grass leaves, with consequent poor marks for appearance. The long-term effect of this fertilizer is limited. The third fertiliser, a mixture of ureaform and urea, was intermediate between the other two in its effects. The second trial, still in progress, is assessing the effect of artificial wear on the release pattern of three slow release N fertilisers - IBDU, ureaform (UF) and polymer-coated urea. In this trial, 150, 250 and 350 kg ha-1 N were applied in three dressings. Only the ureaform product showed a slight improvement in sward appearance as a result of the wear treatment, but the results were generally rather poor. The artificial wear reduced the height of growth in almost all treatments. Reasons for this are discussed. Polymer-coated urea releases nitrogen very slowly in the first weeks after application. There was a tendency for IBDU at 250 kg ha-1 N to give results equal to or better than 350 kg ha-1 as ureaform or polymer-coated urea." |
