Groundwater irrigation efficiency and soil fertility in drylands



The water under your feet in Laos

The water beneath our feet is a valuable irrigation resource for farmers affected by drought in rural Laos, and can increase crop yields and income for farmers. Students at the Faculty of Water Resources and Management have created an experimental site to research groundwater irrigation efficiency and improve soil fertility. They found that the best way to save water is by using drip irrigation, and that the more crops were produced when compost was added to the soil.
