Abstract: The use of accurate and near real time volumetric soil moisture (θv, m3 m−3) measurements informs not only precise irrigation scheduling but also decisions regarding fertiliser applications, feed supply and stock management in non-irrigated farming systems. To assist θv monitoring, capacitance-based AquaCheck (AquaCheck, South Africa) sensors are being increasingly used in precision agriculture applications. However, the performance of these sensors have not been investigated extensively under field conditions with dynamic soil moisture regimes.
