Explain the role of continuous contour trenches in soil consevation.
Answers
Answer:
Explanation:
Contour trenching is an agricultural method that can be readily implemented in arid sub-Saharan regions to allow water, soil conservation and agricultural output to boost. During the growing season when there is less rain between two trenches plants can profit from the subsoil water reserve collected during the rainy season.
Contour trenches break the speed of runoff and the infiltrated water can help to increase the soil moisture regimes for tiny catchments. Contour trenches are used for soil and moisture conservation and forestation reasons on both mountain slopes as well as on degraded and barren waste lands.
