2.1 技术简介

技术定义:

Wooden fences are an effective and relatively cheap way of conserving soil from water erosion by decreasing overland flow. They also increase crop yield by encouraging better infiltration.

2.2 技术的详细说明

说明:

Dry croplands in semi-arid regions are generally subjected to intense soil erosion in hillslopes due to sudden heavy rainfalls. In these areas, conserving soil and water by cheap technologies that could be installed by the farmers with available resources and knowledge becomes important.

Purpose of the Technology: Woven wood fences represent a technology applied and demonstrated successful in semi-arid mountainous dry croplands in Eskişehir, central Anatolia. They consist of wooden posts 150 cm height inserted into the ground and branches woven between these posts. Eroded soil from upslope becomes trapped on the upslope side of the fence and overland flow is decreased. The distance between the fences is determined with respect to soil texture and field gradient. It is 30 m in hillslopes of 10% gradient covered by sandy loams in the Eskişehir region.

Establishment / maintenance activities and inputs: The basic costs are for the materials, its transportation and the labour involved in installation. The posts and branches are derived either from trees on the farmers’ fields or from nearby state-owned forests. For 2009, the cost of installation was about 1350 US$/ha. The maintenance costs of this medium-term (20 years) technology are only the labour needed to repair the damaged fences/terraces after extreme rainfalls. Technological change includes contour (rather than downslope) tillage between the fences, which causes a minor increase (10%) in the expenses of tillage operations.

Natural / human environment: The technology can be applied both by small- and large-scale farmers in quite different soil and slope gradient conditions. Results indicate that crop yield doubles (1300 kg/ha of barley) and soil loss apparently diminishes using this technology.

注释:

Major land use problems (compiler’s opinion): The current dry cropland use requires the fields to be fallow every second year due to insufficient water in the soil. For this reason drought radically decreases crop yield. Owing to heavy rainfall, removal of both topsoil and subsoil occurs in places causing increased stoniness in the soil, which decreases its fertility and makes the tillage operations difficult.

4.1 该技术的技术图纸

技术规范（与技术图纸相关）:

Plan of the site implementation in Eskişehir. Solid lines depict contours at 1 m intervals.
The implementation area (at the centre of the Figure on the left) has a gradient of 10 %. Fence spacing is 30 m and each fence is 60 m long. Posts provide the strength of the structure and are inserted up to 30 cm into the ground. Branches are woven between the posts. Eroded soil trapped on the upslope side produces an earth bank.

Technical knowledge required for field staff / advisors: high

Technical knowledge required for land users: moderate

Main technical functions: control of dispersed runoff: retain / trap, reduction of slope length

Secondary technical functions: increase in organic matter, increase of infiltration, increase / maintain water stored in soil
