Resources such as Langevin's books say that it is proven that growth is better with PH in the 6.5 to 6.8 range. If you read some of the data from soil test laboratories, specifically Western labs AG recommendations, they are stating better to be at 7.5. Any answers on why the difference, is one recommendation older and the newer one better? Why?

A pH of 7 is neutral. I general most nutriants have there best availability at this pH. Large AG' have been grown in a wide range of pH's. Not sure what Western Lab's is smokin, but 7.5 is a little high!

I try to get my ph around 7.2 because I tend to lose alot of alkali throughout the season and it usually settles down to 6.8 or so maybe due to the water table being so high and having some local flooding in the area.

When ever I read something with high PH and pumpkins I always think of Jack La Rue growing his 1400 lbers back in the day, and thats when a 1400 lber was rare to see.

Jack grew all his big ones with a higher PH then most growers like to have theirs at, and for some reason Jack likes his PH in the high 7's , he sure did grow some whoppers with it being that high.

This might have changed for him in the last few years,maybe he or his wife will chime in.

Maybe with all these organic amendments,PH isnt all that important??Maybe??Remember these old PH recommendations are decades old,the playing field & science is changing constantly!Just thinking outside of the box!

After my pH became elevated from mushroom soil I contacted Chad revier since I knew he had some experience in the matter. I came to find that many of his 1400 and 1500 pound pumpkins were grown with soil pH as high as 7.4.
