Functional topdressing soils for lawn growing

摘要

PURPOSE: The functional plastic clay for the growth of a turf grass is provided, thereby neutralizing the hydrogen concentration in the soil with minimizing the stress of the turf grass, inhibiting solidification of the soil and making the color of the turf grass deeper. CONSTITUTION: The functional plastic clay for the growth of a turf grass contains olivine having a diameter of 0.01 to 5 mm as an effective component. For cultivating Zoysiagrass, the olivine-containing functional plastic clay is covered on the fairway of a golf field in a thickness of 1 to 2 mm for 1 or 2 times. For cultivating bentgrass, the olivine-containing functional plastic clay is covered on the putting green of the golf field in a thickness of 0.1 to 0.2 mm for 5 or 20 times.
