Natural Resources Conservation Service (NRCS), formerly known as the Soil Conservation Service (SCS), is an agency of the United States Department of Agriculture (USDA) that provides technical assistance to farmers and other private landowners and managers. Its name was changed in 1994 during the presidency of Bill Clinton to reflect its ...
Techniques for improved soil conservation include crop rotation, cover crops, conservation tillage and planted windbreaks, affect both erosion and fertility. When plants die, they decay and become part of the soil. Code 330 defines standard methods recommended by the U.S. Natural Resources Conservation Service. Farmers have practiced soil ...
The National Cooperative Soil Survey Program (NCSS) is a partnership led by the United States Department of Agriculture's Natural Resources Conservation Service of Federal land management agencies, state agricultural experiment stations, counties, conservation districts, and other special-purpose districts that provide soil survey information necessary for understanding, managing, conserving ...
Soil Erosion Service was created to combat the Dust Bowl and the Great Depression in the United States. The problem of soil erosion was major during the 1930s. The Soil Erosion Service was later moved into the Soil Conservation Service (SCS), and then the Natural Resources Conservation Service (NRCS). [1] [2] [3] [4]
The district now offers program support to both urban and rural residents in a dozen ways—from the Backyard Conservation Program to the Soil Sample Voucher Program—and hundreds of locals have ...
The Soil Conservation Service worked with state governments and universities with established agriculture programs, such as the University of Nebraska, to promote the method to farmers. By 1938, the introduction of new agricultural techniques, such as contour plowing, had reduced soil loss by 65% despite the continuation of the drought.
The United States Forest Service believed that planting trees on the perimeters of farms would reduce wind velocity and lessen evaporation of moisture from the soil. By 1942, 220 million trees had been planted, covering 18,600 square miles (48,000 km 2 ) [ 2 ] in a 100-mile-wide zone from Canada to the Brazos River .
The NRCS curve number is related to soil type, soil infiltration capability, land use, and the depth of the seasonal high water table. To account for different soils' ability to infiltrate, NRCS has divided soils into four hydrologic soil groups (HSGs). They are defined as follows. [1]
