Country: Kazakhstan

Province: Jambyl Region

Country: Kazakhstan

Province: South Kazakhstan Region

Other settlement: distant pastures of A. Sagintayev LLP

The site is located in the foothills with significant difference in elevation

The climate of Jambyl Region is characterized by significant dryness and continentality. The majority of Talas District is located in the desert zone. The warm season is characterized by high air dryness.

Despite substantial thermal resources, considerable lack of moisture limits crop cultivation. The majority of the district’s territory is used for spring, fall and winter grazing. Water supply of pastures is ensured by underground water.

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

Water supply of the farms located in the zone of distant-pasture livestock production; possibilities to utilize idle wells containing highly mineralized water, use water resources in a rational manner, as well as to increase the area of used pastures by way of supplying them with additional water.

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

Technology of reverse osmosis water de-salination in well casing columns

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.

The water-lifting and de-salination technology includes several innovative elements like air-tight wellheads, pipeless water-lifting devices and de-salination module block in absence of high-pressure pump to drive water through them.

Water de-salination with its subsequent separation into soft (permeate) water supplied to consumers and saline concentrate diverted for disposal.

Protected by Patent No. 23118 of the RK:

 - application of water lifting pipes for submersible pumps is excluded;

- pollution of the water-bearing layer is excluded;

- labor input (assembly and dismantling works) decreases by 40-70%;

- power costs (water lifting) decrease by 30%;

- water return of the water-bearing layer due to vacuuming the water reception section increases;

- exclusion of capital costs associated with construction of a heated room for de-salination block.

Economic efficiency

The social effect lies in supplying consumers with high-quality drinking water, and the economic effect – in growing livestock population grazing in distant pastures with additional (de-salinized underground) water supply. The later will increase Kazakhstan’s food security and meat export capacity, as well as enhance the overall environmental condition of distant pastures.

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.

Enhancing water supply of pastures by restoring existing and, where possible, building new well infrastructure; possibility of using water sources with mineralized water that were not used previously, providing livestock crews and cattle on pastures with drinking-quality water.

The R&D works were executed under the theme “Investigating the Process of De-Salinizing Different Types of Mineralized Underground Water and Identifying De-Salination Regimes for Water Supply of Pasturable Land” (2013-2015, amount of funding – 13.5 mln tenge) within the framework of Project 0190/GF3 under Program 055 “Research and scientific-technical activities”, Sub-Program 101 “Grant funding of scientific research” as per the contract with SE “Science Committee of the Ministry of Education and Science of the Republic of Kazakhstan”.  The process of de-salinizing mineralized underground water with different physical and chemical characteristics was designed and adjusted in lab and field conditions on distant pastures.  In addition, the technical standards of operating devices to treat underground water with 2-7 g/l mineralization (as per Patent No. 23118 of the RK) were developed.

The practice was deployed under the R&D Workstream “Scientific substantiation of pasture water supply system based on GIS-technologies with the aim of intensifying distant-pasture livestock production” within the framework of Project “Development of technologies to improve and ensure rational use of pastures to advance distant-pasture livestock production” (2015-2017).
