An accurate determination of the soil hydraulic functions is crucial for using soil water simulation models. The purpose of this study is to compare different methods to estimate hydraulic properties and their effects on the simulation of soil water movement. Soil water retention and hydraulic conductivity functions were either measured in the laboratory (core method) and in the field (instantaneous...
A study was conducted in the North China Plain during the summer maize growth season 1997, using field and laboratory measurement techniques, in order to evaluate the impacts of different tillage practices (conventional tillage (CT), no-tillage (NT) and subsoiling tillage(ST)) on the top soil physical and hydraulic properties. ST caused an important reduction in bulk density in the top 40cm of the...
