I'm Just across the river from Laurens county.
Fescue is the grass of choice for grazing. Probably you have common Bermuda which is spread by seed and is a pest for gardens row crops, and hay crops. If you have any and want to get rid of it, you will have to spend a summer spraying it then spot spraying with Roundup. It, however, will make excellent SUMMER grazing for livestock. It produces pretty good hay. but the yields are far below fescue or Coastal Bermuda. Common bermuda will crowd out Coastal. Coastal is the premier hay crop in upstate SC.
For those in other SC counties, Fescue does not do well East of Columbia. It does not like sandy soil. Coastal does like sandy soil. In Eastern SC, people wanting to graze cows used to have coastal pastures and would no till rye for winter grazing.
Back to Laurens county. You should have a soil test done. Go to the county agent's office in Laurens and get a soil test box. They will give you instructions. I can tell you that your soil is acidic and needs lime. All the upstate soil is acidic. The only SC soil that is basic is in the sea islands, where thousands of years of oyster shells decomposed and added lime to the soil. Tomatoes like basic soils and there is no tomato as good as a John's Island tomato. You may as well get lime spread now. A ton per acre is good. If the trucker wants at least a 7 ton load, that's no problem, just have him spread it thicker. 2 tons per acre is ok. Get some bagged lime from a local store or the local TSC
and spread it on your garden by hand. The granulated type is easier to spread but the fine ground type lasts longer, I'm told, and is effective sooner.
You mentioned goats. I have never raised goats and don't know the stocking rate. Cows require a minimum of 2 acres of good grass in this area, 3 is better, plus hay in winter. Forget about a horse on 3 acres. I don't have a horse, but from observation and conversations with people who do, they need 5 acres, plus hay in winter, plusground feed. For your goats, i would first build faciities. People with goats usually have woven wire fencing with barbed wire on top. I have seen electric fences used for goats. An electric fence MIGHT keep coyotes out. I would put them up at night in a strong building. Locals with goats often keep a donkey in with the goats or guard dogs.
You didn't mention chickens, but I would build a good fence out of 5 foot dog wire for them. This won't keep raccoons out but a low electric fence wire should. Any way, you need a good house to keep them in at night. Other pests of chickens locally are possums and somebody's pet dog.
Deer in gardens: I use an electric fence, 2 strands about 5 inches off the ground with 5 inches between the strand to keep ***** out, and one strand chest high to keep deer out. Has worked so far, but i have heard of deer jumping over a fence that high. Before the fence, I have lost corn crops to deer and *****. Deer also will graze on most other garden crops.
I haven' had trouble with squirrels getting into the garden yet, but daughter many miles away had squirrels eat her corn. Just in case, my suggestion is to shoot every squirrel you see, which won't make much dent in the population but may give you some relief locally. I am unable to have pecans because of squirrels. However, a few cats seems to keep them away.
Have fun.
