Contour plowing or contour farming is the farming practice of plowing and/or planting across a slope following its elevation contour lines. These contour line furrows create a water break, reducing the formation of rills and gullies during heavy precipitation and allowing more time for the water to settle into the soil. [ 1 ]
Contour ploughing orients furrows following the contour lines of the farmed area. Furrows move left and right to maintain a constant altitude, which reduces runoff.Contour plowing was practiced by the ancient Phoenicians for slopes between two and ten percent. [4]
Alley cropping of maize and sweet chestnut, Dordogne, France Maize grown under Faidherbia albida and Borassus akeassii near Banfora, Burkina Faso. Agroforestry (also known as agro-sylviculture or forest farming) is a land use management system that integrates trees with crops or pasture.
A hedge or hedgerow is a line of closely spaced (3 feet or closer) shrubs and sometimes trees, planted and trained to form a barrier or to mark the boundary of an area, such as between neighbouring properties. Hedges that are used to separate a road from adjoining fields or one field from another, and are of sufficient age to incorporate larger ...
Contour strip cropping employs a crop rotation system down a slope to minimize runoff and rain velocity. [1] It is used mainly on gentle slope gradients. The width of protective strips is often higher than that of the row crop strips, so they may effectively intercept runoff.
(pl.) aboiteaux A sluice or conduit built beneath a coastal dike, with a hinged gate or a one-way valve that closes during high tide, preventing salt water from flowing into the sluice and flooding the land behind the dike, but remains open during low tide, allowing fresh water precipitation and irrigation runoff to drain from the land into the sea; or a method of land reclamation which relies ...
Contour trenching (a.k.a., Continuous Contour Trench or CCT) [1] is an agricultural technique that can be easily applied in arid sub-Sahara areas to allow for water, ...
