contour ploughing

Contour ploughing mitigates soil erosion by ploughing across a slope, along elevation lines.

Indeed, contour ploughing, contour brushwood planting, and ditch-and-bund constructions could be said to be types of terrace.

By contour planting and contour ploughing, the rate of water runoff and thus soil erosion can be substantially reduced; this is especially important in riparian zones.

In contour ploughing, the ruts made by the plow run perpendicular rather than parallel to slopes, generally resulting in furrows that curve around the land and are level.

Contour plowing (or contour ploughing) or contour farming is the farming practice of ploughing across a slope following its elevation contour lines.

These usually involve increasing plant diversity, contour ploughing, inter-cropping, minimum or no-tillage systems, and grass strips (with or without grass-covered storm channels or bunds, and with or without brushwood planting along the contours between strips).

The human landscapes of rice cultivation in terraces that follow the natural contours of the escarpments like contour ploughing is a classic feature of the island of Bali and the Banaue Rice Terraces in Benguet, Philippines.
