What did farmers learn to do after the dust bowl drought, c. 1935?

What did they learn after The Dust Bowl Drought in the 1930′s? Like what I mean is what techniques did they learn to say… prepare for another drought?

President Roosevelt ordered that the Civilian Conservation Corps plant a huge belt of more than 200 million trees from Canada to Abilene, Texas, to break the wind, hold water in the soil, and hold the soil itself in place. The administration also began to educate farmers on soil conservation and anti-erosion techniques, including crop rotation, strip farming, contour plowing, terracing and other beneficial farming practices.
