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

Expanding salination of irrigated land

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

Set of measures to enhance the reclamation condition of land (motorized cleaning of the collector, reconstruction of hydro-technical facilities, etc.).

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:

A set of measures to rehabilitate the Darialyk Collector executed to improve land reclamation condition.

Results:

The executed actions allowed lowering the level of ground water occurrence, thus, enhancing the overall land reclamation condition in target area as well as improving water drainage in adjacent areas.

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:

Lowered ground water level and improved reclamation status of irrigated land allowed tenant farmers and daikhan (farmer) associations in Dashoguz Velayat (Region) to increase crop productivity and, thus, gain additional income.

Recommendations:

Major project efforts to enhance the overall land condition in the target area resulted in improved public welfare.  The practice can benefit from the relevant Uzbekistan’s experience (systemic cleaning of collectors) – cleaning of intra-farm water supply networks simultaneously with inter-farm and/or main collector systems.  Uzbekistan’s model demonstrated sharp improvement of reclamation condition of entire land massifs.  Ecosystems are extremely vulnerable and without proper care future generations will have to take much more effort and spend more resources to restore them.
