Abstract
After two years of the football playing feld exploitation ground composite of the carrying layer and sand of the drainage layer was sampled in nine points of the rebuilt plate of the football playing feld. Basic physical properties of the material were determined. Basic upon constant laboratory determined water characteristics general easily, and hardly accessible water content as well as doses of spray irrigation for standard and comfortable satisfying of water demand of the playing feld sward were calculated. It was found that the carrying layer of 14 cm depth may peep, at on easily accessible water content of (comfortable water conditions) about 7.5 mm and generally accessible water (standard conditions) about 10,0 mm water. In dependence of the weather conditions and assumed water comfort every 3–4 days spray irrigation is required. Making use of the water reserve from the drainage layer of retention of about 3 mm the time lapse between irrigations may be prolonged by 1–2 days. Taking into consideration the playing feld surface for direct play the netto water amount used for one irrigation would be respectively 53.5 and 71.4 m3 at the dose 7.5 mm and 10 mm.
