10. We over-limed it and it became alkaline, pH = 7.5 on the last test

When I scuffed off the sod from the lawn to create a new planting bed, the soil measured acidic at about pH=6.0. However, we overlimed the old beds. So, acidic coffee grounds would not be a problem.

The soil was so alkaline that some potatoes developed the "scab" infection, so for the next few seasons, we will be applying fertilzers that are carefully selected to *not* add any calcium or magnesium. That means synthetic nitrogen, and potassium, and no coffee grounds/seedmeal. I am using a soil consultant/agronomist.
