Dear Rocio,
To calibrate the Hydrosense: 1) measure the moisture with the probe and remove in the same place, at the same time, 2-3 moist samples, protect against drying and weigh; 2) drying the samples in an oven at 110 º C until constant weight and weigh again; 3) calculate the soil moisture based on wet and dry weights, 4) repeat the operation once or twice until to obtain two different measures of soil moisture, 5) build a calibration curve with the results and always use it to fix the values ​​obtained by Hydrosense. Repeat all steps for each soil type.
