If not NPK, what are the benchmarks?
I'm posting this as an offshoot of a thread in the regular (chemical? ;-)) lawncare forum, at the request of another gardenweb member, because that thread veered into organics.
That member said a few things in that thread, but I think the point of contention is this statement by him:
I've stopped calculating NPK and have focused instead on feeding my soil.
I responded with this:
I'm curious, what do you mean by focusing on "feeding the soil" without any reference to NPK? I mean, if you are ignoring NPK, what metrics are you actually focusing on when you decide to lay stuff down on your lawn? I'd be grateful if you could provide numbers so that I can really understand what you are doing.
So, I'm posting here out of respect for that poster. But that aside, can anyone answer my question, which is basically, if you reject NPK as a relevant metric, what metrics do you actually refer to when deciding to lay down so much of this or that organic product on your lawns?
