Calibration of soil water content measurements observed with capacitance probes

Soil moisture or soil water content is an important variable for Meteorology, Agronomy, Hydrology and Soil Science. In Argentina, measurements of soil moisture are both spatially and temporally sparsely distributed. There are different methodologies of measuring soil moisture content like the gravim...
