2.1 技术简介

技术定义:

A buffer strip of grass is left uncultivated in the middle of an area of steep sloping cropland to help reduce soil erosion.

2.2 技术的详细说明

说明:

A grass strip, approximately 10m wide is left uncultivated across the upper part of the slope. This buffer strip is followed by an adjacent drainage ditch to enhance the technology’s capability of reducing run-on onto the field further down the slope. Neighbouring land users decided to implement the technology in order to reduce soil erosion on their cropland (wheat, chickpeas and flax), and to prevent disputes about land management practices. Upslope and downslope land users reported a significant reduction of observed rill development and fertility decline, emphasising that the benefits of the grass strip offset the area of crop land lost to it. The farmers paid equally for the lost cropland area.

Establishment / maintenance activities and inputs: Apart from the annual digging of the drainage ditch no establishment activities are required, since the grass strip was simply left uncultivated when the former pasture was turned into cropland. The drainage ditch needs to be cleared out of soil on a regular basis; the grass strip is cut for haymaking once during each growing season. The technology is neither cost nor labour intensive and is easy to implement. Farmers state the area lost to the grass growing as the only disadvantage. However, the grass strip alone does only reduce, not fully prevent soil erosion and should therefore be combined with other SWC technologies such as drainage ditches, terraces and/or agroforestry.

注释:

Major land use problems (compiler’s opinion): severe water erosion (rills and gullies) and subsequent fertility decline

Major land use problems (land users’ perception): fertility decline, soil erosion and washing downslope of seeds before they can sprout.

Type of cropping system and major crops comments: winter wheat and sometimes chickpeas are sown in autumn because farmers lack time for land cultivation in spring, flax and also chickpeas are cultivated in spring
