The real and imaginary parts of the complex permittivity of soils of different textures are calculated at a single microwave frequency 9.78 GHz and at room temperature 330C by wave guide cell method. In the view of active and passive microwave remote sensing, penetration depth for the microwaves within the moist soils of different textures is estimated treating uniform soil moisture profile for near surface soil layer. This was observed that penetration depth has the negative correlation with soil moisture content and hardly depends upon the texture at low soil moisture contents (SMC). Penetration depth decreases as clay portion in the moist soil increases and this effect becomes more significant at higher moisture levels. Further, attenuation or power loss per unit length of the moist soils of different textures is also estimated. Power loss per unit length of the moist soil for the microwave propagation increases as the SMC increases. Further, attenuation also depends on the texture of the soil.
