Evaluation of the effects of incorporation rate and depth of water-retentive amendment materials in sports turf constructions

Popis výsledku v původním jazyce

The objective of the current laboratory study was to assess the effects of a number of amendment materials and the depth of incorporation on water retention. 300 mm rootzone profiles were established in 150 mm diameter plastic cylinders over a 50 mm gravel drainage layer. Five amendment materials (sphagnum peat, compost, zeolite, TerraCottem and Stockosorb) were mixed with a medium-coarse sand at various rates. The upper rootzone layer (0 -- 150 mm) included 50%, 100% and 150% of published or manufacturers' recommended rates of each amendment material. Three amendment rates were included in the lower rootzone layer (150 -- 300 mm): pure sand, half the amendment rate of the top layer, and the same amendment rate as the top layer. The following measurements were made: water retention in individual layers, volumetric water content in the top layer (0 -- 60 mm), shear strength, surface hardness, permanent wilting point. Water retention was significantly influenced by the different amendmen
