The route included in the SER crosses fewer miles of threatened and endangered species habitat, fewer streams and rivers and considerably fewer miles of severely wind erodible
where farmers were required to implement a soil conservation plan on erodible
cropland to be eligible for commodity price supports, the no-till area went from 7,000,000 hectares in 1990 to 25,000,000 in 2004.
Deforestation over thousands of years, steep slopes, and highly erodible
soils combined with intense summer monsoon rainfall has seen an incredible amount of soil erosion from the Loess Plateau, located on the middle reaches of the Yellow River.
technology is an innovative erodible
film technology that sticks to mucous
The reductions in areas under these crops have occurred because of a combination of competition for land from products with rising demand, such as fruit and vegetables; land degradation from overexploitation; government programs to divert erodible
land to pastures and tree crops; and displacement of land through urbanization and infrastructure development.
However, in areas with texture contrast or gradational soils the removal of sandy surface materials may result in the exposure of more clayey, stronger, and less erodible
farmers systematically retired roughly 10 percent of the most erodible
cropland, planting the bulk of it to grass, according to the USDA.
Since it was formed in 1997, the task force has developed several strategies to help reduce blowing dust and stabilize erodible
farm land throughout the Antelope Valley.
This field research was done on highly erodible
Memphis Silt Loarg Soil (Typic hapludalf, silty, mixed, thermic) in 1993 and 1994 to compare the LAI, biomass and yield of snap beans (Phaseolus vulgaris L.
Serpentine "barrens" are rare natural communities composed of grasslands and oak savanna growing around outcrops of serpentine, a magnesium-rich mineral that contributes to dry, acidic, erodible
, nutrient-poor soils.
Pikes Peak granite is highly erodible
if disturbed," the Sierra Club's John Stansfield says.
At present, runoff of fertilizer and pesticides from farms might be managed by one program, efforts to control air pollution raining into the bay might be handled out of another, logging of erodible
lands upstream might be regulated by a third, and safeguarding threatened or endangered fisheries might be coordinated by a fourth.
