There is this great source of management practices for golf courses, that are good for any type of landscape site, not only golf.
This attached article talks about Phosphorus (P) transportation by water flowing out of a garden, golf course or any structure that utilizes P for plants in general.
There are two types of P and leaching (loss) to water is one of the main causes of Eutrophication (basically pollution). Several techniques can be adopted to avoid this loss, but this one I found very interesting, cheap and applicabble to any type of site.
I hope you like it!
