Soil Water Budget and Drought Stress,h of the NFSI profiles were estimated in a correlation analysis between fine root density and soil properties (Hartmann and Wilpert .). Based on the processed NFSI data, the soil water budget model LWF-Brook90 was parameterized, and the dynamic water budget for all NFSI profiles was modelled.

Nitrogen Status and Dynamics in German Forest Soils,uces N-storage in the mineral soil. The median annual N balance for German forest soils between NFSI I and II varies between +2.9 and +7?kg?ha., depending on the harvest regime assumed. Negative N balances occurred mainly in mountain ranges like the Black Forest or the Rhenish Slate Mountains. N sto作者: Intact 時(shí)間: 2025-3-22 14:32 作者: osteopath 時(shí)間: 2025-3-22 17:52
Heavy Metal Stocks and Concentrations in Forest Soils,ed that heavy metals were translocated from the organic layer into the mineral soil, while the total stocks over the entire profile remained more or less constant. For the evaluation of heavy metal contents in the mineral soil, we used precautionary values from the BBodSchV. The contents are for mos作者: 歌曲 時(shí)間: 2025-3-22 23:30
