Soil moisture is difficult to monitor accurately because of the heterogeneity of pore space, bulk density and the soil matrix. There are several types of commercial soil moisture probes available, including those that employ time domain reflectrometry and frequency domain reflectrometry. Calibration of these probes is difficult owing mainly to the difference between soil structures in field and laboratory conditions. The purpose of this group is to share calibration methods and data in order to improve the quality of soil moisture data.
