| Research Abstract |
Using the air infiltration characteristics of a porous cup we developed a device with cheap material that measures the soil moisture and evaporation. This device consists of a porous cup, a transparent polyvinyl-chloride pipe and a silicon stopper. If this device is installed in the soil, soil moisture can be measured, and the evaporation can be measured if it hangs it in the air. For this device, the water level in the pipe is the index of the soil moisture and evaporation. The most important feature of this device is that the water level in the pipe depends on the degree of soil moisture or evaporation is quantified on a daily basis.
