I have about a 5 acre section of pasture that has a ton of Dallis grass. Doesn't look like this stuff produces much forage (when compared to Bermuda and Bahai). I don't have any cool season grasses on the place. What process would I need to go through to convert this area to ryegrass or fescue? Would I need to kill the Dallisgrass or just till and sow? Any suggestions? I'm in the central part of Arkansas.
