Since this is the time for soil tests for next year's growing season, it's a good time for those experienced growers to expound on the optimum nutrient levels needed to grow the heaviest 'kins...

Carbon? Nitrogen? pH? Iron? Calcium? Mg?, etc, etc..

I dont want to seem like an idiot here, but I believe that this type of thing has a forum for it. I believe this should be in the soil prep and analysis area.

My guess would be you are probably already 10 times over the optimums. (I am ) Will be adding all the peat, leaves, and sand I can gather and aford. Backing way off the manure and biosolids.
Here is a rough guide line:
Ca 2000-4000 lb acre
Mg 285-570 lb acre
Phos(as P) 400 lb acre
K (as K) 200 lb acre
SO4 (as S) 200 lb acre
CONN 200-600 micro mhos
Na 10-35 lb acre
NO3 (as N) 40 lb acre

Theses are general gardening optimums... You can get away with higher for AG's.

Look under the North Dakota extension services, and look under the Carrington NDSU extension plot. They have done studies concerning regular pumpkins. I followed that this year, and was happy with two pumpkins putting out just over 800 lbs. The biggest one split.

I believe to start, they recommend 60 lbs of N for pumpkins.
