Contour farming , the practice of tilling sloped land along lines of consistent elevation in order to conserve rainwater and to reduce soil losses from surface erosion. These objectives are achieved by means of furrows, crop rows, and wheel tracks across slopes, all of which act as reservoirs to catch and retain rainwater, thus permitting increased infiltration and more uniform distribution of the water. Contour farming has been practiced for centuries in parts of the world where irrigation farming is important. Although in the United States the technique was first practiced at the turn of the 19th century, straight-line planting in rows parallel to field boundaries and regardless of slopes long remained the prevalent method. Efforts by the U. Soil Conservation Service to promote contouring in the s as an essential part of erosion control eventually led to its widespread adoption. The practice has been proved to reduce fertilizer loss, power and time consumption , and wear on machines, as well as to increase crop yields and reduce erosion.

Farming is one of the oldest and sustainable human activities. As societies evolved from simple to sophisticated lifestyles, human beings began to till land and farm in order to produce their own food. As time passed, man discovered different ways of tilling and farming on different landscapes, including slopes that are notorious for soil erosion. Some of the methods used to date include windbreaks, planting cover crops, planting grass on waterways, and contour cultivation among others. Contour cultivation contour farming, contour plowing, or contour bunding is a sustainable way of farming where farmers plant crops across or perpendicular to slopes to follow the contours of a slope of a field. This arrangement of plants breaks up the flow of water and makes it harder for soil erosion to occur.
The commission taught farmers how to use terracing and contour plowing techniques to preserve the soil. Federal and state government teamed up with universities that had strong agricultural programs, like the University of Nebraska, to set up demonstration plots and show farmers how to use these soil conservation methods. Contour plowing was a method of plowing furrows that follow the curves of the land rather than straight up and down slopes. Furrows that run up and down a slope form a channel that can quickly carry away seeds and topsoil. Contour plowing forms ridges, slows the water flow and helps save precious topsoil. LeRoy Hoffman rented farmland for his entire farming career and remembers when the government urged farmers to change their plowing methods.
These contour lines create a water break which reduces the formation of rills and gullies during times of heavy water run-off; which is a major cause of soil erosion. The water break also allows more time for the water to settle into the soil. This method is also known for preventing tillage erosion.
