Abstract
Turf can be grown by mixing an artificially-granulated soil and turfgrass seeds, sprinkling the resultant seed-soil mixture on a ground and then covering a surface of the thus-sprinkled mixture with an artificially-granulated soil of the same type as the first-mentioned artificially-granulated soil to a thickness at least equal to the average grain size of the seeds but not greater than 5 mm. The artificially-granulated soils contain 0.01-2.00 wt. % of a fertilizer as calculated in terms of effective components of the fertilizer, is pH 6-7 and has an average grain size 0.5-1.5 times the average grain size of the turfgrass seeds. To prepare the seed-soil mixture, the soil is mixed with the turfgrass seeds at a rate of 30-300 g of the soil per gram of the seeds. The seed-soil mixture may be subjected to germination-hastening treatment before being sprinkled on the ground.
