Gabe Brown says he uses cover crops, pastured poultry, and managed grazing on the same land as his primary crop and gets more calories per acre than monoculture farms, but also he has no chemical inputs, his soil is getting richer, and there's far less impact on the environment. And it's not like he doesn't have large farming equipment to do the work with. There's a learning curve and a risk factor in switching, but the alternative is to be dependent on variable fertilizer costs and government subsidies forever while the soil is depleted.
