I'm far enough north that my ground has a good bit of sand in it clay is about 18 inches down . I took the post hole diggers and dug down about a foot in the hay field and the soil is moist . So not much ran off. In the past 2 inches of rain would get me a decent cutting . The coastal and tifton 85 that I planted did well in the drought last year but we are as bad now as we were in august last year .
