| So with all the talk of precision farming, yield mapping, variable rate lime, fertilizer, seed, etc - there's a question I always want to ask:
How far down can we or should we break it? Out of say, an 80 acre field, do you want to break it down and manage it in 10 acre units, 5 acre units, 1 acre units or even smaller while fitting all the inputs "perfectly" for that smallest unit you select?
When do you think we get to the point that "more data" is just "more data" - that it doesn't have a clear, reasonable, practical use?
Should we be breaking it down and managing everything "foot by foot" or "plant by plant"? Where's the line at that it just becomes ridiculous?
Or when you send samples to a soil lab - if the lab reports a sample as 6.2 pH, 26 ppm P (Bray P1), 148 ppm K(neutral ammonium acetate) - and the "true" values (don't ask me how you get them) are actually 6.0 pH, 30 ppm P, 167 ppm K - do you really think that "error" truly affects your bottom line?

Whats the smallest unit of a field you can manage individually?
