I maintained the athletic fields at a small D3 school for several years. Turface or an off brand conditioner will help hold moisture, but when it gets really dry you will still have the same dust problem. Rocks can be controlled by having the team do a 'rock walk' before every practice. Eventually you can get them under control.
Everyone thinks that turf is maintenance free that is certainly not the case. The crumb rubber infill moves and must be broomed back into place, particularly where the players slide. And it must also be supplemented on a regular basis. The rubber keeps the fibers upright, if the fibers are allowed to lay over the sun will cause them to deteriorate and the turf will need to be replaced well before it's normal life span, and the warranty will not cover it unless you can provide proof of regular maintenance. And turf is HOT!! I don't know you deal with that in the South.
DD learned this last weekend. Her TB had their first weekend tournament together at an all turf facility. Clean and well kept. But temps hit 85 - 90. DD said just standing at 3B she could feel it radiating up. Pros and cons to everything.
