Plz, I don't understand this at all
from Internet: (I hope this helps.)
One of the earliest methods of conservation tillage came to be known as contour plowing, or plowing on the contour. Tilling the soil along the gentle slopes of a piece of cropland, instead of up and down the gradient, prevents fertile topsoil from being carried downhill by flowing rainwater.
Contour bunding or contour farming or Contour ploughing is the farming practice of plowing and/or planting across a slope following its elevation contour lines. These contour lines create a water break which reduces the formation of rills and gullies during times of heavy precipitation, allowing more time for the water to settle into the soil.[1] In contour plowing, the ruts made by the plow run perpendicular rather than parallel to the slopes, generally furrows that curve around the land and are level. This method is also known for preventing tillage erosion.[2] Tillage erosion is the soil movement and erosion by tilling a given plot of land.[3] A similar practice is contour bunding where stones are placed around the contours of slopes. Contour ploughing helps to reduce soil erosion.
