Sorry to spoil the picture of pretty flowers: This picture hits me as really anti-ecological, unsustainable, industrial practice using a large space to grow just one thing and it is called MONOCULTURE and it doesn't last. Soon this land will be dry, and it depends directly, instead of on the sun and rain, on the love and care of the creatures around it, but on imported fertilisers and the whims of consumers thousands of miles away. Grow local stuff and keep it varied. If you can't figure out what to grow, ask someone ffrom the area. The results will much more enriching to yourself and to the land, and prettier too.
