METHOD FOR CREATING NATURAL TURF SURFACE

PROBLEM TO BE SOLVED: To provide a method for creating a natural turf surface having good water drainage and not being solidified even after time passes, by which the number of times for water supply and fertilizer application and maintenance costs can be reduced. SOLUTION: The method for creating a natural turf surface 1 comprises the following steps: selecting granules each having a predetermined grain size among porous granules (e.g. volcanic gravels gathered at a quarry site) in accordance with the usage of a turf surface (a selecting step), uniformly spreading the selected porous granules on a crushed stone base layer 2 so as to form a turf base soil layer 3 with an appropriate thickness suitable for a bed soil and according to the kind of turf at the site of reclaimed land (a uniformly spreading step), and vegetating natural turf 4 on the turf base soil layer 3 comprising porous granules to create the natural turf surface (a vegetation step); wherein at least fertilizer alone, or together with a soil ameliorant as necessary, is stuck or adsorbed on or into granules to be used for the porous granule layer 3 at any state before or after, alternatively in the midst of the selection step or the uniformly spreading step.
