2.1 Short description of the Technology

Definition of the Technology:

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 Detailed description of the Technology

Description:

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.

2.7 Introduction of the Technology

Specify how the Technology was introduced:

• during experiments/ research

3.1 Main purpose(s) of the Technology

• reduce, prevent, restore land degradation

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

Cropland

• Annual cropping

Annual cropping - Specify crops:

• legumes and pulses - peas
• fibre crops - flax, hemp, other
• cereals - wheat (spring)

Number of growing seasons per year:

• 1

Specify:

Longest growing period in days: 210Longest growing period from month to month: Mar - Aug

Comments:

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

4.3 Establishment activities

4.4 Costs and inputs needed for establishment

Comments:

Duration of establishment phase: 0 month(s)

4.5 Maintenance/ recurrent activities

4.6 Costs and inputs needed for maintenance/ recurrent activities (per year)

Comments:

Machinery/ tools: tools: spade, sickle

costs per hectare (including adjacent land upslope and dowslope)

4.7 Most important factors affecting the costs

Describe the most determinate factors affecting the costs:

If the technology is not established at the point of the initial cultivation of the cropland, grass clods will need to be transplanted which considerably increases the establishment costs

5.1 Climate

5.2 Topography

5.3 Soils

If available, attach full soil description or specify the available information, e.g. soil type, soil PH/ acidity, Cation Exchange Capacity, nitrogen, salinity etc.

Soil fertility: medium - high

Soil drainage / infiltration: medium - good

5.6 Characteristics of land users applying the Technology

Indicate other relevant characteristics of the land users:

75% of the land users are average wealthy and own 70% of the land (since technology requires space, poor and very poor farmers will find it difficult to implement).

Off-farm income specification: In general, all farmers (including those applying SWC technologies) are highly dependent on off-farm income, which in most cases is earned in Russia either by themselves or by their relatives.

Level of mechanization: Steep slopes do not allow cultivation by tractor or animal traction

Market orientation of production system mixed (subsistence/ commercial): Only surpluses are sold or exchanged for other goods
