| Abstract/Contents: | The drainage systems of three kinds of constructions were tested over a period of four years, beginning in the spring of 1990. A simulated slit drainage construction (bodennahe Bauweise - close to the surface construction [A], rootzone 15cm thick) a drainage layer construction (2 layers [B], rootzone 26 cm thick, drainage layer 12cm comprised of sand 0-2 mm) and a USGA type construction (3 layers [C], rootzone 26 cm thick, 6 cm coarse sand intermediary layer, 12 cm base layer comprised of 3-7 mm sand) were built, with the subsoil and rootzone mixtures designed to have identical composition so as to compare the drainage rather than the systems themselves. Maintenance was also identical, with a minimum of fertilization and irrigation, mowing taking place five times a week with a 6 mm cut, verticulation only performed once a year at the end of winter, and no applications of pesticides or fungicides. The grass seed mixtures were also kept identical. "From 1990 to 1993 the following results were found: The growing . . . period was fastest on construction type C, slower on A and slowest on B. Drought tolerance of the turf stand was best on type A, wilting tendency was greatest on type B. Comparing all three construction types, didease occurrence of Gaeumannomyces and Gerlachia nervalis was lowest on A. Highest incidence of Gaeumannomyces infestation of turf was found on C, and no differences were found in rates of Gerlachia nervalis infestation between B and C. Construction A gave the best turf stand, however, differences decreased over the research period, probably because of lack of mechanical maintenance practices. Fertilizing all three types equally, type A gave the most turf growth, indicating that type A showed the best potential for reducing fertilizer. No differences were found between B and C. Thatch build-up was smallest on construction type A. Measurements of soil water content in the root zone mix showed lower drought susceptibility of the turf on type B compared to C. This is because of the higher water retention of the sand drainage layer, (particle size 0/2) in B compared to the coarse sand layer in C. Better drought resistance on type A is due to a higher water holding capacity of the subsoil. The organic matter of the rootzone mix decreased over the research period from 3.6% to 2.9%. This process was fastest on A and slowest on C and likely due to the decomposition of the relatively easy decomposeable organic substance from the compost. The pH of the rootzone mix decreased on all construction types to 5.8. Despite wear treatments, water infiltration was high at the end of the research period and reached 3mm/min." |
