Global soil organic carbon pool.

Estimates of the size of the global soil organic carbon (SOC) pool have ranged between 700 Pg (Bolin, 1970) and 2946 Pg (Bohn, 1976), with a value of around 1500 Gt to bebetween one-half (e.g., Townsend et al., 1995) and tw...

Relationship between norway spruce status and soil water base cations/aluminum rations in the Czech republic.

There is a concern that soil acidification by acidic deposition, along with the resulting depletion of the labile pool of nutrient cations (e.g. Ca, Mg) and enhanced leaching of Al from soil may contribute to fores...
