| The soil P concentration commonly declines over time by organic management, if the farm does not acquire enough fertilisers or other inputs containing P from outside. An interesting source to supply farms with P is struvite (magnesium‐ammonium phosphate). This mineral easily precipitates when the concentrations of these nutrients is high enough, such as in a toilet separating urine. Struvite may be produced in a wastewater treatment plant, as a method to reduce the P concentration in the water reaching the recipient. If struvite is allowed as a mineral fertiliser in the general fertiliser regulation of the European Union,which is currently under revision, this mineral may be allowed also in certified organic agriculture. A wastewater treatment plant in... |
