Ein Boden setzt sich aus mineralischen Partikeln unterschiedlicher Größe zusammen. Je nach Partikelgröße werden drei Größenklasssen unterschieden: Ton (< 0,002 mm), Schluff (0,002 – 0,063 mm) und Sand (0,063 – 2 mm). Bei einer Partikelgröße über 2 mm spricht man von Grobboden. Die relativen Anteile von Sand, Schluff und Ton lassen sich im sogenannten Bodenartendreieck […]

When we talk about soil moisture, we are referring to the water content. This indicates how much water is in the soil. The water content can be specified in two different ways. The volumetric water content is the ratio of the volume of water to the total volume of the soil sample. The gravimetric water content is the ratio of the mass of water to the mass of the dry […]

A dendrometer is a scientific measuring instrument used to measure the diameter or circumference of a tree trunk over time. It is a key tool in forestry science, ecology, and climate research. A classic application is measuring the annual growth of a tree. This is often done using diameter tapes or mechanical tape dendrometers with an accuracy of […]

As a general rule, dry wood is a very poor conductor of electricity. Water, however, in which nutrients and salts are dissolved, conducts electricity very well. Pure (distilled) water is also a poor conductor. We make use of this relationship to examine the moisture content in the tree. The electrical resistance is measured between two electrically conductive screws [...].
