| Problem solved through this practice |
Water erosion, discharge, uneven distribution of irrigation water, poor yields |
Irrational use of irrigation water and fertilizers; deficit of electric power; low soil bonitet; poor crops productivity; poor quality of agricultural products; soil erosion |
| Tools used in the practice |
Technique and technology for irrigation based on Simultaneous Impulse Sprinkling Kit (KSID-10S) |
Free-flow drip irrigation system (DIS) |
| 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:
Free-flow DIS was installed at the Zhijdalisoj Water Reservoir and was connected to the already operating gravity irrigation piping network. Due to the elevation difference between the pipe inlet and outlet (at the point of entry to the irrigated site) the system generates natural water pressure allowing free-flow DISs installed in gardens to operate without any pumping equipment, i.e. electricity.
Results:
Technical:
thanks to free-flow DIS, water and fertilizers are distributed evenly, strictly according to corresponding norms, in due time and economically (water saving - up to 50%).
Financial and economic:
increased (by 30-40%) crop yields and improved yield quality.
350,000 sum/ha ($150/ha) saved due to electricity saving and no need to repair pumping equipment. |
| 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:
Application of natural (gravity-based) water pressure allows making DISs more affordable for farms located on slope acreage of mountain foothills.
Recommendations:
It is necessary to carry out research to identify locations where free-flow DISs could work thanks to natural water pressure. |
