What are your go-to organic amendments for your tomatoes?

[Fred Hempel]

Soil and soil needs are so very variable. Our soils all need different things. But, it might be nice to touch base on what we are using, and what seems to be working. Here are my major amendments.

Organic compost -- Large scale green-waste pick-up and composting in the San Francisco Bay Area makes uniform and reliable organic compost very affordable. We use it mainly for organic matter and soil structure improvement. Of course some minerals and other benefits.

Powdered Oyster shell -- Our field isn't "low" on calcium. But the Calcium-Magnesium ratio is skewed Magnesium. So we need additional Calcium.

Rabbit Manure -- A very "clean" manure and our main nitrogen source. We are lucky to have a rabbit breeder close-by who produces plenty.

Azomite -- A powdered volcanic rock with lots of trace minerals. It is not clear what all the affects are, but fruit density and flavor seems to be enhanced with Azomite. Applying heavier dose this year. No time for controlled experiments, right now, unfortunately.
