I have recently heard of some technique used in the Netherlands (other
places, too, perhaps) to trap excessive phosphorus that would be
moving in the soluble form from fields. It involves interception with some
form of iron compound. This type of practice seems to be applied in
those cases in which excessive phosphorus has been applied to soils
over time and there are concerns for water quality, public health, etc.
If anyone knows of this practice specifically in detail I would appreciate
an email from them.
