A much more effective way to provide Ca to soil is in the form of
powderd milk. It's very fast.

Why bother? Powdered milk would be more expensive weight for weight than
just using dolomite or lime. And if you have a wood burning fire then the
ash from the fire also provides calcium.


Dolomite or lime are not readily available the way the milk is and
needs to be broken down by microbiota first. It also changes the pH
in the soil. Wood ash is entirely too alkaline for tomatoes and I
would never use it in soil where I grew food.
