Problem solved through this practice |
Water erosion, discharge, uneven distribution of irrigation water, poor yields |
Deterioration of reclamation situation: rising of ground water, land salination |
Tools used in the practice |
Technique and technology for irrigation based on Simultaneous Impulse Sprinkling Kit (KSID-10S) |
Technique and technology of land reclamation via a system of vertical drainage wells (VDW) |
Description of the practice and its results |
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 VDW system set up. Prior to its installation, the area was drained via a horizontal open-type drain-age network ineffective as to reducing the mass of salinized land.
Comprehensive VDW efforts significantly enhanced drainage.
However, currently due to the absence of a single organization responsible for VDW operation, maintenance and repair, the VDW systems recon-structed under World Bank and Asian Development Bank projects do not perform as effectively as ini-tially.
Results:
Financial and economic: Increased cotton yields (from 10-15 up to 30-35 dt/ha).
Technical: Successful response to land salination in 3 districts: ground water table steadily kept at 2-3 m depth leading to a sharp contraction of salinized land area. |
Lessons learnt and recommendations made |
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:
In due time, the model proved useful and timely, as the country urgently needed to increase its cotton yields. The practice demonstrated high efficiency of VDW in combatting land salination.
Recommendations:
1. Establish a special VDW System Maintenance and Operation Department; 2. Build personnel capacity: • Continual training of personnel in the Department and Provincial Hydrogeological and Land Reclamation Expedition; • Drafting and distribution of training materi-als. |
