Última Microbially-mediated P fluxes in calcareous soils as a function of water-extractable phosphate Organic Eprints Schneider, Kimberly D.; Voroney, R. Paul; Lynch, Derek H.; Oberson, Astrid; Frossard, Emmanuel; Bünemann, Else K.. Soil phosphorus (P) tests are designed to indicate plant-available inorganic orthophosphate (Pi), but fail to account for Pi that may become available through organic phosphorus (Po) mineralization. This P source may be especially important in soils with low concentrations of solution and labile Pi. We assessed gross Po mineralization and immobilization using labeling with 33P in four calcareous Alfisols with varying concentrations of Olsen soil test P that were collected from forage fields of dairy farms in Ontario, Canada. Rapid microbial 33P uptake during incubation was found for the soils with the lowest available Pi as indicated by both Olsen soil test P and water-extractable Pi. The tracer incorporation into microbial P after 8 days ranged from 7 to... Tipo: Journal paper Palavras-chave: Soil quality; Environmental aspects.
