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

Land degradation, water loss in the fields; reduction of irrigation and soil flushing efficiency; inefficient distribution of water resources; rising ground water level

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

Technology of laser planning (leveling) of irrigated land

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.

Initially, the laser technology was applied to develop virgin acreage for principal land planning.  Later, it was used for routine land planning (smoothing).

In recent years, the application of laser planning technology almost stopped due to lack of resources, but this case study shows how relevant it is in the current context. 

Actions:

• area (land) leveling (planning);
• table-top and project design works on land planning;
• preparation of equipment;
• preparation of laser equipment;
• laser land planning;
• deep land loosening and administration of organic fertilizers.

 Results:

 Technical:

• increased plot (KZI) ratio (up to 0.92-0.95);
• 25-30% water saving.

 Financial and economic:

• increased crops productivity;
• income from planned (levelled) acreage increased from 2.17 mln sum/ha to 4.6 mln sum/ha.

 Environmental:

• improved land reclamation condition (ground water mineralization decreased, thus, leading to contraction of salinized acreage).

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 demonstrates the need for periodic (routine) laser planning (leveling) of irrigated land to enhance irrigation efficiency.

Recommendations:

For routine land smoothing, it is desirable to combine land laser planning with deep land loosening.
