Thanks, that was a super informative post!
That makes perfect sense to me, and I gather that in some sense only %50 of the Phosphorus is actually usful to the plant or something like that, so you can halve the number indicated.
Are area has been in a serious draught begining early July, and still continues.
When one says established lawn, does that mean an exisiting lawn without respect for qualtity, or does it also have something to do with a lawns health?
If you overdo it on K and P, is it just wasted, or can their be some negative effect?

Any other thoughts would be appreciated.
Thanks so much
