what about excessive chlorine levels applied on turf when using muriate of potash for a potassium source. some blends(Lesco)are near 9% chlorine content. at the 1 lb of n2 per 1,000 sqft. the chlorine is almost .4 of a lb per 1,000 sqft.. can't be good, do you have any literature on this chlorine topic.
