Abstract EN
Agricultural drainage ditches can deliver high loads of phosphorus (P) to surface water.
Installation of filter structures containing P sorbing materials (PSMs), including gypsum, is an emerging practice that has shown promise to reduce these P loads.
The objective of this study was to evaluate what effect soil amendment with gypsum would have on soil P concentrations and forms in a laboratory incubation experiment.
Gypsum was saturated at two levels with P, and applied to a silt loam and a sandy loam at two rates.
The treated soils were incubated in the laboratory at 25°C, and samples were collected on eight dates between 0 and 183 days after amendment.
Spent gypsum application did not significantly increase soil water-extractable or Mehlich 3 P when applied at typical agronomic rates.
This appears to be a viable strategy to remove P from agricultural drainage waters but does not appear to provide any additional P fertilizer value.
