Who invented contour plowing?

Contour plowing, a technique used to reduce soil erosion and conserve water, was not invented by a single individual but rather developed over time through agricultural practices. It gained prominence in the 1930s during the Dust Bowl era in the United States as farmers sought effective methods to combat soil degradation. The technique involves plowing along the contours of the land rather than in straight lines, which helps to slow water runoff and promote soil conservation.
