soil moisture probe datum

Catalogue: GRDC Updates
In Figure 5, we show soil water measured at various depths using gravimetric methods and EnviroSCAN@" probes at Norwin in Queensland during 2010 - 2012 (Dalgliesh 2013)... The techniques also arise out of the aerospace industries, where the earliest approaches were developed for reducing errors in predictions of missile or spacecraft positions estimated from measurements of speed and direction... The really good news is that methods used in assimilating models and soil moisture probes could be used to improve the quality of the information from the model, and also the quality of information from the probes...

Data from soil moisture probes is being used with Yield Prophet modelling to improve soil-type characterisations.. Mr D'Emden says initial results from the 2014 probes showed that half of the GS30 (June/July) Yield Prophet estimates were within 300 kilograms per hectare of the final crop yield, increasing to 70 per cent within 300kg at GS90, with a median difference between the Yield Prophet GS90 estimates and final yield of 0.35t/ha... The total PAW estimates require further calibration to account for the influence of subsoil constraints such as salinity, sodicity or acidity...
