What is two circle irrigation?



A circular trench is dug at a distance of about a foot away from the main stem. A second trench is also dug around the first trench. Water is irrigated in the space between the two trenches. Coconut husks, dried leaves can also be placed in the two trenches and covered lightly with fine soil. The husks and dried leaves absorb the water like a sponge and release the water during high temperatures to the crop roots and keep the area moist. This type of irrigation can be done for fruit, palm and other trees.
