Nitrogen deposition into forests

The Geneva "Convention on Long-range Transboundary Air Pollution" has entered into force in 1983. It achieved a reduction of the long-range transport of pollutants in the air and thus mitigate the impact of pollutants on the environment. The data collected within the framework of ICP Forests records the pollutant inputs in the forest and the effect on it.

Composition of the soil solution

The soil solution serves as an important indicator of forest condition. It is the key medium for nutrient uptake by plants and, in polluted soils, for the uptake of pollutants. The soil solution distributes substances in the soil and depending on circumstances also into the groundwater.

Nutritional status of forests

The nutritional status of trees is an important indicator to assess their vitality. Various factors are evaluated: nutrient concentrations and nutrient contents in the leaves or needles, as well as the ratios between nutrients.

Composition of litterfall

Litterfall is an important part of the nutrient cycle in forests. It presents a pathway for nutrients from the trees to the soil. During the decomposition of litter, the nutrients are made available to plants and can then be absorbed by the roots. The composition of the litterfall is therefore an important parameter for describing the ecosystem.
