Problem solved through this practice

Surface irrigation is associated with considerable water losses, uneven root zone moistening, increasing irrigation-induced soil erosion, low labor productivity of irrigators, low irrigation system efficiency, etc.

Tools used in the practice

Low-pressure impulse mist irrigation system

Description of the practice and its results


- Construction of low-pressure impulse mist irrigation system (procurement of polyethylene piping, pumping unit, cassette filter);
- Installation of pumping equipment, settling pond, impulse mist sprinkling nozzles.


Financial and economic:

rational use of irrigation water; enhanced efficiency of water and land resources use; low cost ($4,164/ha) compared to the basic option ($4,326/ha).


no damage to atmosphere, water and soil and production of ecologically clean agricultural produce.


the system operates under low pressure enough to ensure sufficient mist sprinkling irrigation (high-quality artificial rain) creating the necessary microclimate stimulating proper plant growth and development, ensuring even and highly uniform soil moistening; the system is easy to assemble and operate.


reduced irrigation costs on behalf of water users due to smaller volume of consumed irrigation water; increased profitability of farms due to higher crops productivity.

Lessons learnt and recommendations made

Lessons learnt:

Low-pressure impulse mist irrigation system allows improving the overall conditions in greenhouses and/or lemon tree nurseries – rain-like water distribution curbs irrigation-induced soil erosion and unproductive water losses in the course of irrigation.


It is necessary to widely deploy low-pressure impulse mist sprinkling systems with the aim of irrigation automation and saving irrigation water.

Brief information on the project

Project title: Low-pressure impulse mist sprinkling system for greenhouses and/or lemon tree nurseries.

Project duration: Apr 2012-Oct 2013.

Project goal and objectives: development and deployment of new low-pressure impulse mist irrigation system for greenhouses and lemon tree nurseries in the context of acute water shortage to ensure even distribution of irrigation water, exclude irrigation-induced soil erosion and unproductive irrigation water losses, thus, leading to water and power saving.

Project beneficiaries: “Ziroatkor” Farm.
