Spade –an essential tool - must be used regularly to check uniformity.

Tensiometers – encourage over watering, bad for multiple depths- rarely repeatable

Computer models – too many assumptions for modern agriculture – see presentations on Etgage and weather stations.

Gypsum Block – far too inaccurate in our experience

Aquaflex – installation difficult and destroys the soil structure – averages readings which is dangerous as some plants may be wet while others dry.

Theta probe – Expensive, short cable runs, difficult to install at multiple depths, poor software.

Neutron Probe – usually a once a week service, which is not enough –expensive, not accurate enough near the soil surface, measures too large a volume of soil for most UK crops.

Gopher – poor repeatability, slow to use, difficult to interpret.

Profile Probe – quite new and unproven long-term? – quite expensive, poor software, susceptible readings - 220° round access tube only?

C-Probe – expensive due to radio communication, poor software, low quality results

EnviroSCAN- continuous, well proven, scientifically accepted, repeatable, excellent software, remote collection of data.

Diviner – portable partner of the EnviroSCAN with the same excellent properties.
