rotdybden
Ro td ybden is the vertical extent of a plant's root system within the soil. The term is used to describe how deep roots penetrate the soil profile and can be defined in several ways. In some contexts rotdybden refers to the deepest layer that contains any roots; in others, it denotes the depth from which most water and nutrients are absorbed, i.e., the effective rooting depth. Researchers may distinguish maximum rooting depth from effective rooting depth because deeper roots can exist beyond the zone of active uptake, especially under drought conditions.
Measurement of rotdybden is challenging. Common approaches include soil coring and trenching to recover root material,
Several factors influence rotdybden. Plant species and age, soil texture and structure, and the depth to restrictive
Importance and applications: rotdybden affects water uptake, drought resilience, nutrient acquisition, and anchorage. It informs land
