The International Union of Soil Sciences (IUSS) is the global union of soil scientists. The objectives of the IUSS are to promote all branches of soil science, and to support all soil scientists across the world in the pursuit of their activities. This website provides information for IUSS members and those interested in soil science.

Uncertainty in Predicting Soil Water and Plant Available Water at High-Resolution Scales

Soil moisture and plant available soil water (PAW) is a foundational data to predict crop production and inform tactical and strategic decisions on farm management and system design. There are several methods to monitor or estimate soil water and PAW e.g. sensors, proximal sensing, remote sensing, modelling (process based & artificial intelligent) across filed and soil profile, each with their particular limitations and uncertainties. This PhD research will explore issues for uncertainty analysis of soil moisture and PAW at sub-paddock scale and implications of uncertainty from different observations and modelling approach. How high spatial variabilities will constraint model calibration and accurate estimations.
