- •
Dissolved reactive P played a limited role in P transport compared to PP and dissolved unreactive P (DURP).
- •
Major proportion of the DURP fraction is fine colloidal (0.2–0.45 um size class).
- •
Phosphorus is associated with soil particles or soil colloids in runoff, through flow, leachate and soil solution.
- •
Higher level of Exchangeable Na and exchangeable sodium percentage affect subsoil P transport in loam soil.
