I've got a couple plots that are are in loblolly stands where I've planted the cut rows after the first thinning and then expanded the planting after the second thinning. Each one is laid out to cover 1 acre, but the actual planted area goes from about .25 acre to .75 acre over the life of the stand.
It has taken anywhere from 2500 to 4,000# lime /acre in 2-3 applications to get the pH into the 6-6.5 range on my sandy clay loam soils, but once established they are some of my most productive plots in terms of deer and turkey use. I prefer LS-1 Clover to Durana. It just performs better all around for me. I started the plots off with a mix of Crimson and LS-1 and over time the Crimson has faded out and the LS-1 persists. In the fall I drill cereal rye and broadcast 200# of 0-20-20 /acre and 300# of pelletized lime. The cereal rye seems to do better in the shade than wheat or oats.
One of the challenges with doing this is the pine straw that builds up. The extra fertilizer seems to really boost straw production in the surrounding pines. The best solution I have found is to carve off a burn block around each of these plots and let a cool backing fire creep through every other year.
One of the advantages of doing this is the clover seems to tolerate our hot summers much better. These are the only plots where my clover doesn't go dormant in July and August.
