Contour plowing is a practice that involves tilling the land in a pattern that follows the contours What farming method is plowing around a hill and not on it? Explain. These objectives are achieved by means of furrows, crop rows, and wheel tracks across slopes, all of which act as reservoirs to catch and retain rainwater, thus permitting increased infiltration and more uniform distribution of the water. What is are the functions of diverse organisms? Although in the United States the technique was first practiced at the turn of the 19th century, straight-line planting in rows parallel to field boundaries and regardless of slopes long remained the prevalent method. This happens when terracing retains too much water, which is absorbed into the ground. Contour farming has been practiced for centuries in parts of the world where irrigation farming is important.

OR ThE TEXTBOOK ANSWER Contour plowing prevents erosion, and no- till farming reduces topsoil erosion. This can end up causing more damaging runoff than in unterraced areas. When these conditions are not met, Some facilitative strips can be revenue oriented, others cost oriented, depending on whether the strip biomass is directed toward higher yields or economizes on imported nutrients. Reduces the erosion hazard in each furrow and permits you to irrigate efficiently land too steep for downhill Because of this, farmland stays fertile much longer. Why is small-scale farming still common in many developing countries?

Disadvantages:High soil moisture loss, Contour ploughing mitigates soil erosion by ploughing across a slope, along elevation lines. Alternatives to ploughing, such as the no till method, have the potential to actually build soil levels and humus, and may be suitable to smaller, more intensively cultivated plots, and to farming on poor, shallow or degraded soils which will only be further damaged by ploughing.
