An irrigation method using clay pots that are buried under ground
OLLA
SAY "OH-Yah"
Ollas are terracotta clay vessels that have been used for irrigation by agrarian peoples for centuries. The unglazed pots are simply buried in the soil with the neck sticking out. They are filled with water that slowly seeps out to the roots of the plants. The roots in turn “embrace” the olla and extract the precious moisture as needed.
