What is clay pot irrigation?
Clay pot irrigation in its simplest form consists of unglazed baked clay pots, which are buried up to the neck in the soil and filled with water. This method is one of the most efficient systems of irrigation known and is ideal for many small farmers.
Do clay pots release water?
Because the pores in the clay pot are small, the water does not freely flow out of the pot. A suction force is created by soil moisture tension as well as the plant roots. If soil is dry, the water inside the olla will release faster as the soil roots “pull” it out. There will be a dense mat of plant roots.
Who invented the olla?
This irrigation technology is an ancient method, thought to have originated in Northern Africa with evidence of use in China for over 4000 years and still practiced today in several countries, notably India, Iran, Brazil (Bulten, 2006; Power, 1985; Yadav, 1974; Anon, 1978 and 1983) and Burkina Faso (Laker, 2000; AE …

This method is one of the most efficient systems of irrigation known and is ideal for many small farmers.
How do you keep moisture in terracotta pots?
Water Deeply Soak the entire pot each time you irrigate until water runs out the bottom (this actually doesn’t usually take much water in smaller pots). Make sure pots have drainage holes so excess water can escape in order to avoid a root rot problem.
Where did the olla come from?

What is olla made of?
The OLLAS are made of unglazed, porous clay. When an OLLA is filled with water, the water is pulled out through the wall of the pot, due to Soil Moisture Tension.
How long does an olla last?
On a conservative side, fill the OLLAS 2 times weekly. If your area gets around 30 inches of rain annually, you may be able to go for 5-7 days without filling the OLLA. If mulch is used as a cover, and your area gets a little rain monthly, it is possible to go up to 10 days without refilling.
Does olla irrigation work?
Therefore, olla irrigation is extremely water efficient and prevents excessive evaporation and water runoff. It is also better for the root systems of the plants. It promotes deep watering and dense root growth which facilitates more efficient nutrient and water uptake.
What is Ollas clingclay pot irrigation?
Clay pot irrigation using ollas is a self-regulating gardening system that provides sub-surface watering of plants, that is simple, affordable, and easy to implement, making it ideal for small farmers and gardeners.
Are clay pots good for irrigation?
As Geoff Lawton says, clay pots can make your garden drought-proof. Little water is lost to evaporation or run-off. Spanish settlers introduced this irrigation technique to the Americas in colonial times. Agriculture and gardening specialists are teaching it, and olla use is making a comeback in New Mexico and the American West.
When was drip irrigation first used?
Primitive drip irrigation has been used since ancient times. Fan Shengzhi shu, written in China during the first century BCE, describes the use of buried, unglazed clay pots filled with water, sometimes referred to as Ollas, as a means of irrigation.
What are clay pot dishes?
Clay pot dishes are sometimes labeled as “hot pot” or “hotpot” dishes on the menus of Chinese restaurants in English-speaking areas of the world, but they should not be confused with hot pot dishes that are served in a large metal bowl and cooked at the table.
