1 Swish 1 to 2 teaspoons of a vegetable-based oil (coconut, sesame, or olive) in your mouth for 20 minutes, spit it out, rinse with warm water, and brush well after rinsing, says, Marc Lowenberg, DDS, a dentist at Lowenberg, Lituchy & Kantor in New York City.
Atrazine is the most widely-used conservation tillage herbicide in corn and is a critical rotation product to manage weed resistance. Conservation tillage makes cropland much less vulnerable to soil erosion, which is reduced by as much as 90 percent when compared to intensive tillage.
Many other references with historical soil erosion information have been compiled by Sundquist (2005). Between 1982 and 2003, total soil erosion on all cropland and CRP land in the United States decreased from over 3 billion tons per year to 1.7 billion tons (Table 3). This is a decrease of nearly 43 percent.There are several likely reasons for this decline.ata from the 2003 Annual NRI, the most up-to-date NRI information available, indicate that average soil erosion rates on all cropland and CRP land have decreased more than 38 percent since 1982. In 2003, the soil erosion rate was estimated at 4.5 tons per acre per year, compared to 7.3 tons per acre per year in 1982.
