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

• Inefficient management of water resources;
• Inefficient planning of water distribution

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

DUV 2/0.005-10 Water Level Sensor

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 DUV 2/0,005-10 Sensor was deployed and demonstrated its efficiency in Jambyl and Southern Kazakhstan Regions.  It allowed to visually and in real-time observe the dynamics of water level fluctuations and completely exclude manual operations and subjectivity in the process of taking readings – a relevant task in the environment of transition to market economy.

Water level sensors were installed in 17 hydro-posts in Southern Kazakhstan Region (Maktaaral District).  In Jambyl Region, the same sensors were installed in 3 hydro-posts in Merke District.

Results:

Technical:

a) immediate data exchange on water volume passing through every water lead to the fields of agricultural producers (farms) as well as automatic transfer of this information to stakeholder organizations (branch of “Kazvodkhoz” Republican State Enterprise (RSE), etc.);

b) archiving the data coming from hydro-posts with its subsequent processing in the form of reports.

Technical and economic:

1) “all in one” – all components of DUV 2/0.005-10 are assembled into one unit/casing, do not require any additional modules and adjustments, i.e. it is an out-of-the-box universal tool to execute monitoring of water reserves irrespective of the availability of power supply and other technical and weather conditions.  The simple Sensor’s design facilitates installation and start-up and commissioning, as well as allows minimizing labor costs;

2) DUV 2/0.005-10 is flexible in terms of installation, data transfer methods, measurement subject (water level or hydro-lock position, etc.);

3) the cost of the measuring unit is 3-4 times less compared to currently available alternatives;

4) DUV 2/0.005-10 designed architecture allows increasing the number of controlled points and performing an integrated monitoring of the whole network.

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:

Deployment of the DUV 2/0.005-10 Water Level Sensor led to increased precision of water level and consumption measurements and higher promptness of information collection compared to any known methods.

Using the device in the conditions of water resources deficiency, on the one hand, will ensure objective accounting of water use and, on the other hand, will promote water conservation among water users which will lead to more efficient technological development of agro-industrial complex and higher labor productivity.

Recommendations:

The success of deploying water level sensors in project hydro-posts facilitated execution of measures to disseminate the positive experience of using the device in the water sector.  Their effect will be even more significant as enhanced quantity and quality indicators will ensure effective management of water resources and water conservation with simultaneous development of irrigated agriculture.
