Paragraph 8

■ One of the time-tested methods of dealing with water erosion is terracing—creating hill-side ridges—to reduce runoff. ■ Another newer, highly effective tool in the soil conservation tool kit is conservation tillage, which includes both no tillage and minimum tillage. ■ In conventional farming, land is plowed, disked, or harrowed to prepare the seedbed, seed is drilled into the soil with a planter, and row crops are cultivated with a mechanical cultivator two or three times to control weeds. ■ With minimum tillage, farmers simply drill seeds directly into the soil. The only tillage is a one-time disturbance in a narrow band of soil where the seeds are inserted, leaving the remainder of the soil undisturbed, covered by crop residues and thus resistant to both water and wind erosion.
