In starting bench terraces it is best to locate the position of the balks on contour lines at regular intervals, and begin by throwing a furrow upslope and another downward. The balks thus started should be seeded to grass and kept sodded or planted to shrubs. The s

In starting bench terraces it is best to locate the position of the balks on contour lines at regular intervals, and begin by throwing a furrow upslope and another downward. The balks thus started should be seeded to grass and kept sodded or planted to shrubs. The subsequent plowing on each belt of plowland should be with a reversible hillside plow, throwing the earth down- ward.* The crop rows, too, should run on the contour lines. In time the balks will become steeply sloping banks fixed by the- 19.
