Vattenförande

Vattenförande is a term used in soil science to describe the capacity of a soil to conduct or transmit water. It is a measure of how easily water can move through the soil profile. Soils with a high vattenförande capacity can transmit water quickly and efficiently, while those with a low capacity may allow water to accumulate and lead to waterlogging.

Vattenförande is influenced by several factors, including the soil's texture, structure, and porosity. Soils with a high proportion of sand and coarse particles tend to have a higher vattenförande capacity than those with a high proportion of clay and fine particles. This is because sand and coarse particles have larger pores that allow water to flow through more easily. Soil structure and porosity can also affect vattenförande by influencing the soil's ability to retain and transmit water.

In agricultural and environmental contexts, vattenförande is an important factor to consider. Soils with high vattenförande capacities can help to prevent waterlogging and reduce the risk of erosion, while also allowing crops to access the water they need to grow. In contrast, soils with low vattenförande capacities may require additional management practices to prevent waterlogging and ensure that crops receive adequate water.

Vattenförande is commonly measured using techniques such as infiltration tests, in which a known volume of water is applied to the soil surface and the rate at which it infiltrates the soil is measured. These measurements can provide valuable insights into the vattenförande capacity of a soil and help inform decisions about soil management and conservation practices.
