You'll definately want to do a soil test after cutting the timber. Pine tends to be very acidic, but you can "fix" this after looking at your results. You didn't mention if you were going bulldoze the stumps off after logging or not. This will be a major factor on whether you'll be able to get a tractor and disc in to work your plot. Your clovers will be great for the deer, but bad for the horses. If you eventually will try to hay it, definately no clover then unless you want it for cattle. We use alot of timothy and brohem(sp?) grasses in our pastures here. Both are very hardy and both seem tolerant for both deer and horses. Through in a few pounds of alfalfa also. It will die off in a few years, but good browsing while it lasts. The brohem grass tends to be more moisture tolerant, so good in low areas. Taz
