Two dimensional evaluation of soil property for agriculture

Temperature response of soil is measured using a radiation thermometry and thermocouples with pulse heating technique for agriculture application. Temperature response of various water contents of the soils is evaluated using radiation thermometer and pulse heating technique. The infrared radiation is a non-contact and non-destructive technique to detect the properties or interior conditions of a material from its temperature changes on the surface. The thermal property could calculate based on the phase lag of the temperature by thermocouples. Decay lifetime of surface temperature as soil is calculated using exponential curve with two decay component. Decay lifetime of varies with components & water contents of soil. Dynamic thermal characteristics of soil are suggested to be useful for evaluation of agriculture.
