You should raise the pH by adding limestone. This will raise the Ca and Mg but they are not too high now except for blueberries. Also your K is very low. That needs to be raised to at least 175, mine is about 600 without applying any.

My Ca is 3500 and Mg 300 just for comparison.

what should the ph be raised to for apples and pears?

6.5 is optimum for apple and pear.

You need ton acre to raise ph .5 so need 2 tons for ph 6.5 mix in soil tiller best way go deep tiller. Surface applied take years to get in root zone and wash away easily. I gave rates on acre not clear size planting. Apple trees in zone 9 take special selecting in my zone 8b take luck have crop cold long winter for chilling hours just don't happen very often.

The amount of limestone needed to raise the pH a given amount depends on the cation exchange capacity of the soil. So whoever did the soil test would be the place to get that information. Was there anything on the test about CEC? If you know that number you can make an estimate.

They gave me that information yes fruitnut they said 4.5 lbs of lime per 100 sq ft to raise the ph to 6.5 which sounds correct considering my soil is sand. They also said .3 lbs of potassium per 100 sq ft and .2 lbs nitrogen per 100 sq ft.
