Quote from: Carl Nichols on May 24, 2012, 11:23:15 AMOne question about the firm conditions at Cal Club -- does anyone know what kind of sand they used to cap the course (as I understand they did when they renovated) and/or the kinds of grass out there? The sand in the divot mix is really dark, and the greens are a very dark green. The fairway grass is also interesting. I can't answer your question about the fairway sand type, but I know they created a "sand gradient" on all fairways where they laid down 4" of new sand and then blended it in with the underlying soil to a depth of 8-10". This might account for the dark color you noticed. The grass varieties in the fairways are a mix of three different fine fescues and Colonial bentgrass. Greens are bentgrass (A1/A4 mix). The color of the greens is due to the protocol employed to maintain the pH of the soil in a range that favors bentgrass and suppresses poa. I don't know exactly how the protocol works.
