Some ranchers get convinced tilling of the desert soils will result in more forage for their cows. Needless to say in a desert environment this does not work. It may promote some extra grass for 1 or or 2 years max, but after that forage is reduced. The natural soil ecosystem is disrupted harming all vegetation including those plants cattle feed on. Roots of plants are torn up and worst of all the soil is exposed leading to desication and quicker drying, the best way to kill desert plants.
