The Laboratory analysis of the moisture characteristics of soil samples is carried out using pressure plate extractors. Using this equipment the moisture release curve (the amount of water available within the soil at different pressures) can be produced. This enables parameters such as field capacity, wilting point and hydraulic conductivity to be calculated for a particular soil sample.
The results have a variety of practical applications: soil classification and soil survey, the optimisation of irrigation and drainage in improving crop yields, and the calibration of soil water measuring apparatus for field use.
