2.1 Short description of the Technology

Definition of the Technology:

Stone faced bund is embankment constructed from stone & soil along the contour at upper part to reduce velocity of run of & length of slope with collection ditch in the uper part.

2.2 Detailed description of the Technology

Description:

Description:- is constructed from soil embankment at the upper part. The layer of regular sheped stone embankement at lower side along the contour line. Excavated collection ditch at the uper part. Have sound foundation at lower side. Has a berm between collection ditch & soil embankement. Purpose:- To cut longer slopes into series of slopes. To increase time of concentration & infiltration rate. To decrease velocity of run off. To colect top soil, as a result to protect erosion, to increase yield at last forming a bench. Establishment/ maintenance:- Layout contour line across the slope remark the line of collection ditch, construct embandkment of soil with compaction & construct stone embankment in the outer (lower) side & requires proper foundation. Arranage the labour forces & require external inputs. Environment:- Low rain fall area, less soil depth & moisture stressed areas, low prolduction (yield) areas, on cultivated land use type, which have 8-30% slope.

Comments (type of project, etc.):

National natural resource development of conservation dept.

3.2 Current land use type(s) where the Technology is applied

Cropland

• Annual cropping
• Perennial (non-woody) cropping
• Tree and shrub cropping

Annual cropping - Specify crops:

• cereals - maize
• cereals - sorghum

• cowpeas

• chat

• coffee

Number of growing seasons per year:

• 2

Specify:

Longest growing period in days: 250 Longest growing period from month to month: Apr - Dec Second longest growing period in days: 180 Second longest growing period from month to month: Apr - Sep

Is crop rotation practiced?

Yes

If yes, specify:

sorghum 2st, the maize, sorghum with maize, maize the cow pea.

Comments:

Major land use problems (compiler’s opinion): Absence of applications of land use & forest policy shortage of farm cultivated land. Absence of responsibility to develop protect all land use type population growth pressure, High way run off desposal structure. Intensive cultivation of land.

Major land use problems (land users’ perception): Shortage of farm land; population growth (Increase of family size) decrease of production yield of farm; soil errosion, monocropping system povertiy.

Type of cropping system and major crops comments: Annual croping:- sorghum 2st, the maize, sorghum with maize, maize the cow pea.
