Firstly see that the decomposed granite is properly compacted, if not it might cause irregularities on the surface of your synthetic grass and this can cause affects on the roll of you ball. With a help of hose, lightly spray over the decomposed granite. See that you don't saturate it, now compact the decomposed granite to ensure you have a solid compaction and make sure you do this several times. In case if there are any ridges, bumps or dips, smooth them out with your shovel or rack.
Helpful tip: Always ensure to keep the surface solid and smooth consistently. You must know that a one inch rise over 1 to 2 feet will add a lot of contour once the artificial grass is added. Synthetic turf has to fit like a glove to the surface. Adding too much of slope will make the ball roll fast and it may roll off your green. A good basic guideline is for every 10 to 12 feet in length the decomposed granite will drop the slope 1 inch.
The aim of this survey was to study the microbial population in several infilled synthetic turf as well as in natural grass fields. In addition, other surfaces from public areas and from athletic training facilities were also sampled. Colonies suspected to be Staphylococcus aureus that were positively or negatively identified. S. aureus is a bacterium - common inhabitant of human skin and can cause different kinds of skin infections; they have also been implicated in certain types of food poisoning that can cause serious medical problems such as toxic shock syndrome.
Strains of S. aureus which is resistant to antibiotics are becoming more common, particularly in medical settings. There have been reports recently of methicillin resistant S. aureus causing infection in athletes. With an increase in athlete infections, there is a concern when it comes to infilled turf systems. However there are some indications that the source of these bacteria might be more closely associated with locker room activity than with the infill system, conclusive evidence is not currently available.
