Look in France, they actually to work the fields like this, as well as other parts of Europe & think about the warmer climates and what to plant even in the winters months such as barley etc, when the harvest of these crops is done. Using fertiliser into the soil, as well as using the types of systems, I been talking about. You see it when you go on holiday & also when they water their plants & then pump sprinkler systems in between. You know an advantage with global warming would mean gifarres possibly grazing in our farm fields from time to time, working with the zoos, where they could keep the trees trim they their nutrients in too, from all those berries, maybe even apples etc we don't pick or could go to waste, these and other animals would love it xxx Beloud
