testing the water-permeability of a ricefields soil

how fast seeps the water of the inner cylinder into the soil?

To know how qualified a plot of land is for growing rice you must test its water-permeability

They throw water one bucket after the other into the cylinders till the soil beneath is saturated with water. Then they pour more water only into the outer cylinder and watch how quickly the water of the inner cylinder will disappear.
You need hard-working helpers to lug the heavy buckets around.
