Description of the SLM Approach
Short description of the Approach
Terraces are built on a slope land which as a raised bank made up of earth or stone with vertical or sloping sides and an approximately flat top to control soil erosion and preserve and enhance soil fertility.
Detailed description of the Approach
Aims / objectives: A terrace has a raised bank made up of earth or stone with vertical or sloping sides and a flat top. It can reduce slope angle and length, wrap runoff, increase infiltration and reduce soil loss. Crops can grow well because water increases in the soil. The ground cover is improved. Terraces can be constructed by manual labor or machine. Firstly, surveying the slope hills and determining width of terraces according to the slope angle and soil texture. Secondly, leveling up the slope and constructing the banks. Thirdly, maintaining. The terraces are implemented together by state, local A terrace has a raised bank of earth or stone with vertical or sloping sides and a approximately flat top. It can reduce slope angle and length, retain runoff, increase infiltration and reduce the soil loss. Crops can grow well because water increases in soils. Meanwhile, ground cover is improved. Terrace can be constructed by manual labor or machine. Firstly, determining the width of the field according to the slope angle and soil texture. Secondly, putting the topsoil aside. Thirdly, leveling up the slope and constructing banks. At last, putting the topsoil to the top of the flat surface.
