Non-contact water content measurement of soil based on thermal imaging

The water contents of soil must be monitored and controlled for glowing plants in the field, because measuring of water content is one of most important technique for the agriculture. The temperature response of soil is measured by using thermo-viewer and infrared radiation thermometry, which are non-contact to soil. It is suggested to be useful for thermal characterization of soil. Thermal response of the soil may be affected by properties of soil surface such as, water content, thermal diffusion and thermal transfer from specimens. Dynamic thermal characteristics of soil are suggested to be useful for evaluation of soil agriculture.
