In this study, suction plates were installed in a loamy soil with the aim of determining the P transport patterns and processes in the soil before and after the application of biogas digestate. Prior to the application of biogas digestate, the pore water concentrations of dissolved reactive P (DRP) were significantly lower than the total P (TP) concentrations, with DRP/TP ratios increasing from 0.03 to 0.89. After fertilizer application, the TP and DRP pore water concentrations increased 400‐fold. The DRP/TP ratio remained almost constant at 0.83. After 220 mm of precipitation, 4.5% of the P mass applied was leached to below the 50‐cm soil depth, indicating the general mobility of P i...
