Tilling the Sonoran Desert for cattle

Some Sonoran ranchers are 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 over the long run forage is reduced. The natural soil ecosystem is disrupted, harming all vegetation including plants cattle feed on. Roots of plants are torn up and worst of all the soil is exposed leading to desiccation, a sure way to kill desert plants.
