Hydrosense Soil Moisture Readings 2001

Graph showing % of moisture content by volume (all values are approximate) - May: OM0C2 = unavailable, OM2C0 = 27.5%, OM0C0 = 31.5%, Uncut = 35%; June: OM0C2 = 38%, OM2C0 = 31%, OM0C0 = 29%, Uncut = 29%; July: OM0C2 = 28%, OM2C0 = 21%, OM0C0 = 19%, Uncut = 18%; August: OM0C2 = 24%, OM2C0 = 18%, OM0C0 = 19%, Uncut = 22%; September: OM0C2 = 29%, OM2C0 = 23.5%, OM0C0 = 21%, Uncut = 24%; November: OM0C2 = 46.5%, OM2C0 = 41%, OM0C0 = 43%, Uncut = 38.5%; December: OM0C2 = 54%, OM2C0 = 46%, OM0C0 = 42.5%, Uncut = 39.5%

Hydrosense readings are not adjusted for actual values based on calibration data so they reflect relative volume moisture contents at this time.
