My take on it is that it usually involves studying your land to determine what will best grow there because you are going to work with those conditions rather than fighting them. Then planting non-GMO seeds of cultivars that are likely to thrive in that location. Generally you're not going to engage in monoculture and the livestock will be turned out to pasture rather than going to feed lots or worse. It's also less intensive and the soil has time to rest and replenish itself. Many small time farmers live this way. If you try it, you might be able to turn your farm into a hotspot for agrotourism.
