Here we go...
Hendrick N.D & Black K.A "Growing Media.."1994 (p36) make a simple statement about micro-organisms and decomposition of OM and the resulting depletion of soluble nitrogen and Nitrogen Deficiency syndrome...quote ."Only the material in contact with the soil will be decompsing. Draw-down of nitrogen will be minimal. Biological activity will gradually and painlessly mix the decayed organic matter into the soil.
Little soil nitrogen will be removed by chunky pine bark mulches. But if the bark contains a high proportion of fines, which settle to the soil surface, there can be some draw-down (and temporary toxicity problems)."
