This is a simple demonstration of some of the principles of holistic management. Three small plots of bare ground. One is left bare. One is broken up, as if from the hooves of animals. And one is broken up and has straw on it. Then each plot receives the same amount of water sprinkled on top.
Later in the day, the bare plot is completely dry, even if you dig under the surface. The next plot is dry on top but there is still moisture under the surface. And the one with straw is still moist, even up to the surface.
