How does contour plowing conserve soil? Contour plowing/ploughing conserves soil by following the lay of the land and creating ridges that form a water break to prevent soil erosion. Furrows that do not follow the lay of the land cause rapid runoff during rainfall by forming a convenient channel for the water to flow downhill.

Contour farming | Description, Uses, & Benefits | Britannica Contour ploughing mitigates soil erosion by ploughing across a slope, along elevation lines. Alternatives to ploughing, such as the no till method, have the potential to actually build soil levels and humus, and may be suitable to smaller, more intensively cultivated plots, and to farming on poor, shallow or degraded soils which will only be further damaged by ploughing. Disadvantages:High soil moisture loss, destroys soil structure, compacts wet soil. Advantages: Saves harvests and can prevent diseases from spreading Certain layers of plants will absorb minerals and water from the soil more effectively than others. Farming across the slope helps to shorten slope lengths, slowing down runoff water so it can soak into the soil. Contour farming slows water down and lets it soak into the soil. 2 Combine contour farming with cover cropping and other conservation practices for more soil fertility and slope protection.

Labor is often less expensive than machinery and fossil fuels. Disadvantages. Inter-crops maintain the soil fertility as the nutrient uptake is made from both layers of soil. How can polyculture like intercropping, crop rotation, and agroforestry make agriculture more sustainable? Web | 4 HM-3 BluEarth-ES ES32 165/65R15 The term strip cropping also refers to a method of dry farming sometimes used in areas including parts of the Great Plains of the United States and the Prairies of Canada. 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. Advantages John David Jackson, Patricia Meglich, Robert Mathis, Sean Valentine, Organizational Behavior: Managing People and Organizations, Jean Phillips, Ricky W. Griffin, Stanley Gully. It acts as an insurance against failure of crops in abnormal year. The basic disadvantages of site contours are the time and money to Soil Conservation Service to promote contouring in the 1930s as an essential part of erosion control eventually led to its widespread adoption.
