HydraProbe selected to be used in Canada’s RISMA Network for Agricultural Monitoring

0

A new study published in the Soil Science Society of America Journal investigated the field performance of 5 soil moisture instruments in heavy clay soils in the RISMA network.

The HydraProbe outperformed TDR and capacitance-based soil sensors in terms of stability and accuracy in Manitoba’s agricultural soil. Much of soil in the Canadian Prairie farmland is vertisolic.

Soils with clayey (>60% clay content) glacio-lacustrine parent materials is characterized by high soil water holding capacity and low hydraulic conductivity. This unique soil is analytically difficult for most commercially available sensors. The Hydra Probe was recalibrated for this soil and was found to have no measurable bias and a very high level of accuracy, unlike the other 4 sensors involved in the study.
