Filed: 1988-05-26
Abstract: PURPOSE:To make it possible to measure soil moisture in digital values highly accurately, by detecting the change in pressure in a water column tube caused by the change in amount of water in the water column tube whose water permeable tip part is pushed into soil as the change in electric signal. CONSTITUTION:A cap 2 comprising water permeable ceramics is attached to the lower end part of a water column tube 1. A diaphragm type pressure sensor 3 is mounted on the upper part of the side surface of the tube 1. At first, a plug 4 is removed, and the tube 1 is filled with deaerated water. The plug 4 is attached again. There is no air in the tube 1. When the tube 1 is inserted into soil, the soil absorbs the water in the tube 1. Thus, atmospheric pressure in the tube 1 is lowered. At this time, the drier the soil, the larger the absorbing power, with increases in the pressure change. Therefore, the drying degree of the soil can be found. The output signal of the sensor 3 is made to be a control signal of an automatic water sprinkling apparatus. When water is supplied, a water injecting cock 5 is opened, and the water is injected into water holding part 7. The cock 5 is closed, and a cock 6 is opened. The water is injected into the tube 1 through a pipe 8.
