Poor maintenance of existing infrastructure and irrational use of water are causes for the low (overall) irrigation efficiency.

This may have an impact on the salt balance and the irrigation efficiency or sufficiency.

The National Development Plan (1989-1994) called for an increase in irrigation efficiency and the use of existent infrastructure.

The lower the irrigation efficiency, the higher the losses.

Farmers have adapted by significantly improving irrigation efficiency and shifting even more land into the production of high-value crops.

They developed a low-current electric soil humidity sensor which uses light detection to control water pipe valves and improve irrigation efficiency.

In irrigation projects it is impossible to achieve 100% irrigation efficiency where all the irrigation water is consumed by the plants.

The maximum attainable irrigation efficiency is about 70% but usually it is less than 60%.

Improving the irrigation efficiency of Cooum upstream is one of the main objectives of the project.

While field-level irrigation efficiencies may be low due to the predominance of flood irrigation, the overall system efficiency is quite high due to return flows.
