Root research is executed to improve the insight into the possibilities for root growth (depth and concentration) of the root system of trees and plants. In general, it is important for all plants to have a dense and extensive root system in the soil. An extensive root system allows the plant to benefit from a large volume of soil. If sufficient quantities of nutrients and water are present the absorption will be larger if the root system is more extensive. Measuring the root system also is a useful means of localizing physical and/or chemical barriers in the soil profile.
If the root system researched deviates substantially from an ‘ordinary’ root system, then this is usually due to the following profile characteristics:
- Presence of layers that are hard to penetrate by roots, for example, plough layers, bog ore, heavy clay and loam layers.
- The sharp contrast in profile, e.g. clay to sand, a soil rich of humus to a soil poor of humus (sand), etc.
- High groundwater level.
The single root auger is used to take undisturbed samples for root investigations in soils with low penetration resistance. Samples with a length of 15 cm can be taken to a depth of max. 1 m.
