Calcium oxalate (Ca oxalate) is an insoluble biomineral that forms in plants and fungi, and occurs in soils
across many types of ecosystems. Assessing how Ca oxalate may shape ecosystem Ca cycling requires
information on the distribution of Ca oxalate among plant biomass, detritus, and mineral soil, and how
it...
Acid deposition and repeated biomass harvest have decreased
soil calcium (Ca) availability in many temperate forests worldwide, yet
existing methods for assessing available soil Ca do not fully characterize
soil Ca forms. To account for discrepancies in ecosystem Ca budgets, it
has been hypothesized that the highly insoluble biomineral Ca...
Calcium (Ca) is an essential macronutrient that is increasingly recognized as a biogeochemical factor that influences ecosystem structure and function. Progress in understanding the sustainability of ecosystem Ca supply has been hampered by a lack of information on the various forms and pools of Ca in forest ecosystems. In particular,...
