Kahlschlagbedingte Veränderungen im Wurzelraum eines Buchenniederwaldes auf Rendzinawiss Jura (Basel-Land) on a clearcut stand of 19 a. Selected observations like beech root vitality and contents of soil water and soil elements in stand compared to the cleartcut area are presented in this paper. After one year of tree removal, soil water contents on the clearcut area were significa

Der Einfluß von Bodenbearbeitung und N-Düngung auf die Verteilung von 14C-markierten Assimilaten aufo respond to nutrient limiting conditions. Estimation of rhizodeposition for field-grown oilseed-rape plants (. L.) using .C-pulse labelling technique was the objective of our present work. Treatments consisted of two soil tillage systems (ploughing/surface tillage, ‘Horsch’) and two N rates (0 and

Thus the troublesome assay of the notoriously low activities and labile enzymes of the pathway is avoided. Quantification of steady-state mR

These results show that a repeated biowaste compost fertilization has a quantitative and qualitative influence on the N mineralization potential of soils.

From these results we conclude that in maize prolonged reduction of the tonoplast H. gradient may play an important role in ammonium toxicity. In rice, this reduction is still smaller as rice effectively restored raised vacuolar .H under conditions of increased NH. permeation into the vacuole (... 1998).
