Geologic wind erosion is a part of the land forming
process. Wind erosion is accelerated by human activities which disturb
the protective cover on the soil surface. Trough
proper land management, wind erosion accelerated by human activities can
be reduced to acceptable levels. Wind
erosion is a major problem in New Mexico. The
1992 National Resources Inventory conducted by USDA Natural Resources Conservation
Service found 58% of the cropland, 48% of the rangeland, and 12.8% of the pastureland
eroding above T.
Soil
erosion removes not only the soil resource, but also organic matter and
nutrients. Over time, eroded soils provide less rooting area, store less
soil moisture, and provide lower crop yields and reduced crop quality.
This
guide is designed to provide an understanding of the wind erosion process,
to provide a consistent methodology to estimate wind erosion, and provide
an understanding of how conservation practices reduce wind erosion. This
guide is to be used to develop resource management systems that promote
the sustainability of the soil resource. New
Mexico will now use the Wind Erosion Equation (WEQ) Excel Spreadsheet to run the management period
method of WEQ. It contains circular
2 updates to model. We no longer
need to use the Fuller/Pfeiffer table to adjust the output. |
