I know that we often see above 6.8 as OK for Pumpkins but I just learned
this
at an Orchard class Thursday. 6.2 - 6.8 allows the plants to take up a good
balance of Magnesium & Calcium. Above 6.8 starts to restrict the uptake of
Mag, (not sure if it was Mag or Calcium above 6.8) but one of them is locked
up above the 6.8. Another interesting fact is there is about 35,000,000
living organisms in a tablespoon of healthy earth. Some Herbicides can kill
them and they are needed for plants to take up nutrients.

George and List, On a chart I have Calcium uptake drops off about 8.5 and
Magnesium uptake drops off about 9.2! IRON uptake drops off about 6.5-Boron
starts to drop off at 7.0 -Copper and Zinc start their decline at 7.2 -
Magnesium uptake is not at its peak till your pH reaches 7.3- Calcium is not
at its peak till you pH is 6.8 This chart can be found in the Gardens Alive
Catalog. Call 812-537-8650 and they will send you one. Best of luck to all in
2001
