Phosphorus uptake in simulated soil-root experimental systems
1992
Ravina, I. | Shaviv, A. | Shnek, M.
Simulated soil-root experimental systems were used to investigate the effect of proton excretion on P uptake from simulated soils. The simulated soils consisted of a mixture of agar and suspensions of a Ca-montmorillonite clay and CaCO3 that had been previously reacted with P solutions for short (1/2h) medium (2d) and long (30d) periods. P uptake decreased with an increase in reaction time. It was inversely proportional to the pH of the excreted solution and to the CaCO3 content of the simulated soil. Inducing a flux of water toward the simulated root reduced P uptake.
