Water erosion, discharge, uneven distribution of irrigation water, poor yields

Acute shortage of irrigation water

Technique and technology for irrigation based on Simultaneous Impulse Sprinkling Kit (KSID-10S)

Measures to restore natural springs: arrangement of stone protection fencing around springs and installation of water-release pipes

Actions:

Deployment of the Simultaneous Impulse Sprinkling Kit (KSID-10S) allowing extremely uniform and simultaneous dispersion of irrigation water across all sections of arable pasture or hayfield meadow.  Water expenditure at the impulse device makes 0.05-0.3 l/sec and 0.25-2.0 l/sec in the irrigation pipeline, thus, reducing (3-4 times) the costs associated with the pipeline network installation compared to other sprinkling systems (kits). The pipeline network is built of 15-25 mm diameter pipes easy to transport and assemble in mountainous conditions.

Technical characteristics:

Operation modes: automatic and manual

Irrigated area: 10 ha

Water consumption: up to 100 m³/day

Average sprinkling (rain) intensity: 0.002-0.008 mm/min

EFFICIENCY: 99%

MOC: 98%

Watering automation level: 100%

Results:

• Ensured water supply according to crops requirements with the account of changing weather conditions and moisture deposits in active soil layer;
• Elimination of : 1) water-induced soil erosion, 2) puddling and 3) discharge run-off;
• No need for water recirculation among irrigation sections.

Actions
For project purposes, 10 springs were selected still able to exert water to the surface. Project actions included arrangement of stone protection fencing around springs to prevent cattle from trampling the springs. To allow water release, drain pipes were installed in protection stone walls.

Results
Financial and economic:
The economic effect of livestock production and irriga-tion development exceeding 100,000 USD.

Technical
Enhanced (by up to 30-40%) supply of irrigation and drinking water in the area; drafted “Rules of Using General Use Water Facilities for Personal and Domestic Needs Located on the territory of the Rural District”.

Lessons learnt:

The advantages of impulse sprinkling irrigation were confirmed by the research efforts on other test sites of KAZNIIVKh in Jambyl Region that allowed increasing biological productivity of Golden Delicious apple variety by 10.1-36.8%, and commercial productivity – by 16.6-49.4% compared to conventional sprinkling irrigation systems.

Recommendations:

It is necessary to continue application of similar practices in foothill areas in Central Asia subject to power supply shortages.

Lessons learnt:
The practice demonstrated the advantages of restoring springs and the need to regularly maintain water bodies

Recommendations:
It is necessary to continue the efforts not only in Kazakhstan, but also across the region. For example, it is possible to rehabilitate multiple springs and water accumulators (like “sardoba” or underground “kyariz”) across all Central Asia.
