This paper presents and tests a practical and easy method for setting up a tension table using sand layers obtained as quartz powder in the determination of the soil moisture retention curve up to 100 hPa. Twenty-eight undisturbed cores with varying clay (105 to 316 g kg-1) and organic matter contents (1.98 to 3.90 dag kg-1) along with a mini tensiometer were used to test the sand table efficiency. The results showed that the sand tension table was very reliable when measuring soil water retention […]
