Problem solved through this practice |
Water erosion, discharge, uneven distribution of irrigation water, poor yields |
Increasing secondary land salination, deterioration of col-lector and drainage system (CDS) |
Tools used in the practice |
Technique and technology for irrigation based on Simultaneous Impulse Sprinkling Kit (KSID-10S) |
A set of measures to enhance land reclamation condition (collector cleaning using special equipment, reconstruction of hydraulic engineering installations, etc.) |
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: The capital repair of inter-farm West Karmakshi Collector (WKC) is necessitated by the fact that in its current condition the Collector didn't provide for timely drainage of drainages and discharge water from cropland in the Left-Bank Massif.
Results:
Financial and economic: Increased crop productivity, mainly rice and forage crops
Technical: Enhanced reclamation condition of land in the Left-Bank Massif |
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: Allocation of resources for cleaning CDS proved more efficient than other target actions
Recommendations: Regular and timely execution of running and capital collector cleaning is necessary to ensure its proper operation |
