Subject: lowering ph
Brandon,
Here are a couple articles that may help you decide what your choices are to
lower your pH.

MY SOIL pH IS TOO HIGH. HOW CAN I BRING IT BACK DOWN TO THE OPTIMUM pH
RANGE?
The addition of alkaline materials such as lime, poultry manure or wood
ashes to the soil can raise the pH value to levels which are higher than the
optimum range (5.8 to 6.5 for most plants) to insure good plant growth. This
will occur if excessive a mounts of these materials are added to a soil
either all at once or over a long period of time. For plants that thrive
best in the pH range of 5.8 to 6.5, soil pH values above 6.5 can cause plant
deficiencies of important micronutrients such as zinc and manganese which
are still in the soil but "tied-up" and unavailable to the plant.

pH--LOWER
Before modifying the soil pH, make sure to have a soil test to determine the
current pH.
To lower the pH (or make more acidic) by one pH point, supply roughly 15
pounds of garden or elemental sulfur per 1000 square feet, depending on soil
type. More sulfur would be needed for clay soils; less for sandy types.
Incorporate the sulfur into the soil or spread on top of the ground. Water
well.
It may take a year or two for the soil pH to reflect the change.
The use of pine needles and peat moss will also acidify the soil, though it
is difficult to state accurate amounts needed.

My soil test indicates that my soil ph is 8.5. What is the best way to
lower it for next season? Also, it says to add 2 lbs of nitrogen per 1000
sq. feet (pure nitrogen). Would you use a mainly nitrogen based fertilizer,
or ??? The phosphorus is at an excessive level, so it advised me not to add
any more of that. Thank-you for any replies.
