What did the pueblo people use to grow crops in a dry land

With the sedentary lifestyle, Pueblo people depended on farming to sustain their families.

They used to grow crops in the dry land because they developed a technique to conserve water. They used Pumice - a derived of volcanic rock - because it served like a sponge. It could absorb water - like a storage that retained the liquid - and released over time.

Another technique was to built small depressions in the land surrounded by a wall for the conservation of the seeds to be planted.

With these techniques, they seeded vegetables like corn because is a plant that tolerates the sun and grows tall.
