tobacco, corn and soybeans and the farming of land that is too steep.
Scientists generally consider cropland erosion levels tolerable in Virginia when eroded topsoil losses are less than 4 tons per acre per year. The rate at which soil erodes due to water depends on a variety of factors—including soil type, length, steepness of slope, amount of vegetative cover, and amount and rate of water runoff.
One simple, cost-effective solution to solving erosion problems on cropland is conservation tillage — planting crops with little or no plowing of the land.
