Square foot gardening worked great for us. Bugs were a problem trying to go organic, but we ended up covering them in small hoop houses of some sort of sheer material my wife found. Used less water and kept the bugs off. But our jalapenos were “spoiled” in that they were shady and well cared for and didn’t end up spicy at all.
I’m “raising” goats on 45 acres of forest. We’re only doing it for the ag exemption for now, and I only have 2 right now, so I can’t say I have a lot of experience or testing. But we’ve gone with high-tensile electric. I’m not sure that I’ve got enough wires to stop the goats, although the Kerr Center says it should work. I’ve still got to put in gates, fill gulleys, and run the jumpers at corners. But the advantage is that it is strong enough to take a tree falling on it and spring back up (but not three trees falling on it and staying there for 3 months while you’re out of town), and can handle cattle rubbing on it, whereas the normal tiny electric wires aren’t. And since it is electric, the cattle aren’t supposed to rub on it much.
It’s much easier to pull by hand than barbed wire, because you can leave the coil on a spinning jenny on one end and drag the lighter free end. On flat ground in a pasture, just putting a handle on a barbed wire roll isn’t that bad, though. It’s cheaper than barbed wire just on wire price, and you use half the line poles. And its safer than barbed if you get horses or something like that that you care about scratches and scars.
Also, if your ground is hard, or you are digging holes by hand, look into floating braces as well. High tensile requires deep holes. Floating braces let you use 1/3 of the holes. But you’ll still need h-braces for gates, as floating braces only push, they won’t pull. (They push against the force of the fence pulling on the corner pole, but can’t pull against the force of a gate trying to bend a pole over.)
You can make money with as little as one calf, depending on how you do it. I’ve got a cousin that just buys a calf every year, raises it up to eatin’ size, and then sells it. (Or gets it slaughtered and keeps the beef themselves, I can’t remember for sure. Either way, they were definitely profitable.) We’re thinking about raising one on our land, but I’ve still got to get someone from the county extension office to come out and make sure I have enough grass growing in all the trees to support one.
