Última Kinetics of microbial phosphorus uptake in cultivated soils Organic Eprints Oehl, Fritz; Oberson, Astrid; Probst, Mirijam; Fliessbach, Andreas; Roth, Hans-Rudolf; Frossard, Emmanuel. Knowledge about the role of microorganisms in P cycling at conditions of constant soil respiration rates and constant size of microbially bound P is lacking. To study the kinetics of microbial P uptake and cycling under such conditions, soils differing in biological activity were 33PO4 labelled by introducing a carrier-free tracer solution and incubated for 56 days. The 33PO4 incorporation into the fraction of microbial P releasable by chloroform treatment (Pchl) was assessed and the isotopic composition [=specific activity (SA); SA=33PO4/31PO4] of Pchl and soil solution P compared. Soils were taken from a 20-year-old field experiment including a nonfertilised control (NON), a minerally fertilised conventional (MIN) and two organic farming systems...
