The objects of the invention are to provide a low cost, stable, portable, and rugged field-use device that measures wet density, moisture content, and dry density in soils that have been constructed for use as road beds and building foundations. This data is used to ensure the quality ...
The desired soil moisture content depends on the field capacity (FC) and the permanent wilting point (PWP).FC means how much water the soil can hold after the excess drains off. It displays the balance of water and air in the ground’s pores. There is not enough oxygen if the moisture...
Development of autonomous vehicle for measuring soil moisture content in forest This research aims to develop an autonomous vehicle for measuring soil moisture content in forest.In this research, we investigate a suitable vehicle and s... M Iease,Y Sato,Y Kiga - 《Proceedings of Jsme Annual Con...
The dielectric soil property can be used as a parameter to measure the soil moisture content, because the dielectric constant of water is much larger than the dielectric constant of the other soil components. Soil moisture sensor can be used to automate the traditional irrigation systems based on...

A waveguide assembly adapted for use with a time domain reflectrometry device for use in measuring the moisture content in soils and other mediums. A waveguide assembly comprised of a plurality of waveguide conductors (probes) for insertion into the soil are connected to a coaxial cable. An el...
PURPOSE:To easily control the condition of a change in soil density, etc., and to permit the easy and exact checking of a moisture content by inserting a sensor into the soil and measuring the heat resistance value (inverse number of heat conductivity) of the soil. CONSTITUTION:Samples of ...
