How is soil carbon stock in old-growth boreal forests affected by management? por Dahl, Jenny

“…It is likely that this was caused by disturbance of the humus layer during harvesting and site preparation, and lack of litter fall during the clear cut period. Mineral soil carbon stock was not significantly affected by management, indicating that above ground operations have little effect on deeper soil layers. …”

Soil type affects biological phosphorus cycling more than soil management por Frasier, Ileana, Noellemeyer, Elke, Gili, Adriana, Gomez, María Florencia, Uhaldegaray, Mauricio Gaston, Quiroga, Alberto Raul, Fernandez, Romina, Alvarez, Lucila

“…A nonlinear relationship between metabolic quotient and MBP was found in the Ustipsamment but not in the Paleustoll. Soil management was more related to microbe-plant P competition during periods of active growth in the Paleustoll, while in the non-P limited soil (Ustipsamment), environmental conditions and the presence of active rhizosphere stimulate microbial activity, shown by seasonal variations, increasing P mineralization rates to sustain microbial and plant P demand.…”
