The particle size distribution analysis data is usually expressed as the percentage (by mass) of material retained in a sieve at each particle size category. For example: the rootzone analysis in figure 2, 41.33 % of the material is classified as medium sand (particles with a diameter between 0.5 and 0.25 mm). Figure 2.

Rootzone mixes composed of sand and organic matter should be premixed away from the construction site. Materials should only be placed on site once uniform mixing has occurred. Trucks should straddle drain lines and dump their loads directly over the gravel covered drains. The rootzone is the layer under the sward in which the grass roots live and breathe and this is really the starting point in the long-term success of any green or pitch. An ideal rootzone for healthy grass is natural, well structured sandy loam and if you were building a lawn at home then this would be the first choice. Fine sand particle accumulations on the green's surface may cause irregularities of water movement and the overall physical characteristics of the rootzone.
