pH
We've already seen how knowing the pH of our soil isn't all that useful, other than as
one of the indicators that shows if our practices are moving our soil in the right direction,
often toward a balance point somewhere between 6 and 7. I wouldn't even worry too much
about that.
Actually, one of the main reasons I wouldn't worry is because soil pH fluctuates substan-
tially over time — not only throughout the seasons, but over the course of a matter of days.
Temperature, moisture, biological activity — all of these have an effect. Often pH tests
give wild swings of up to 2 points over a 24-hour period. You'll get a pH number on a pro-
fessional soil test, and that's where I leave it.
