A field maintenance supplier came out to our baseball field and took soil samples. He said we have way to much sand and not enough clay. We have brick dust on top and we are wanting to make improvements. He said somebody must have put a bunch of sand in the soil sometime before the brick dust was added. He said we needed more clay so the water would drain into the soil better. I thought clay made it harder for that to happen? He's not talking about calcined clay. He's talking about excavated clay soil. He said we need to dig up the brick dust and till this clay into the existing soil and top with soil conditioner like Turface. I was planning on putting Marmix on top of the brick dust and then using a soil conditioner as topdressing. Anybody have any insight on this that can help me out?
