Phosphorous Pollution

When I was getting my degree, we were taught that phosphorous does not move.  In the modern world we hear of problems created by phosphorous in our surface waters.  Recent issues in Lake Erie, especially in the Toledo area is teaching us that phosphorous does move.  Very little phosphorous can also cause big problems.  Why is the problem surfacing now.  In many places farmers have been cutting back.  Nutrient stratification could be an issue.  No-Till could be an issue.  Joe Nester, A consultant in Ohio has been looking at rainfall pH as an issue.  He has run some simple tests and found that dissolved phosphorous does increase as rainfall pH approached 6 or a bit higher.
