14.27 Soil Moisture Measuring System Watermark

Soil & CropsSoil Moisture Measuremnt

Soil moisture sensors that measure the moisture tension in the soil are read out with the soil moisture meter Watermark. The measuring principle is similar to that of the gypsum block system. The special sensors however do not dissolve in the soil and have a more consistent distribution of pores so that more accurate measurements are possible.
