Abstract
Soil water status is extremely important and necessary for successful work and reliable results in research in agronomy and environmental sciences as well as in practical applications in plant production. There are direct and indirect methods for soil water measurements. Measuring with tensiometers is an indirect method, based on water matric potential measurements. Tensiometers consist of porous ceramic cup connected to a vacuum gauge through a rigid water-filled tube. Working interval is between 80 – 85 kPa (theoretically up to 100 kPa), which makes them useful for irrigation scheduling, but unsuitable for water matric potential measurements in dry soils.
