Which farming technique was developed to modify the impact of the 1930s Dust Bowl storms in the US?

Dryland farming was developed in the 1930s to modify the impact of the Dust Bowl storms in the US. It encompasses specific agricultural techniques for the non-irrigated cultivation of crops. It includes the presence of a cool wet season usually in winter, which charges the soil with virtually all the moisture that the crops will receive prior to harvest, followed by a warm dry season.

Dryland farming is also associated with arid conditions, areas prone to drought or areas having scarce water-resources. In the US, California, Colorado, Oregon and Wyoming are a few of the states where dry farming is practiced for a variety of crops.

requiring that farmers continually adapt to the lack of moisture in a given crop cycle,

Dryland famed crops may include winter wheat, corn, beans, sunflowers, or even watermelon. Successful Dryland farming is possible with as little as 230 millimeters (9 inches) of precipitation a year. Native American tribes in the arid Southwest survived for thousands of years on dryland farming.

Moisture must be captured until the crop can utilize it. Techniques include summer fallow rotation in which one crop is grown on two seasons’ precipitation, leaving standing stubble and crop residue to trap snow and preventing runoff by terracing fields. Terracing Is also practiced by farmers on a smaller scale by laying out the direction of furrows to slow water runoff downhill, usually by plowing along contours.
