Quantifying spatial distribution of soil moisture using a cosmic ray and capacitance sensor network

This study combines soil moisture capacitance probes and cosmic-ray neutron probe with a Fuzzy Inference System to estimate variability of soil moisture in a ∼28 ha circle over time. The technique demonstrates that the cosmic-ray neutron probe's average neutron count and a network of capacitance probes may be useful for estimating spatial and temporal variability in soil moisture patterns within the probe's footprint.
