How about hot, sweet, and sticky? First thing that come to mind with your request so you don't only get a sticky but a vid too.

Have a good one!

More good info, especially for peat-based mediums. Not too difficult to follow...

How come in some pH charts it states phosphorus is more available at a low pH and other charts at a higher pH and some both?
There is a discrepancy with manganese as well. Does anyone have an explanation for this? Is phosphorous more available at a high or low pH?
