How can I make the soil rich enough for cauliflower

Question

I am planting cauliflowers next to a river and I would like to know if the soil is rich enough or if I need to make it richer. I would like my garden to be organic, so any way I can enrich the soil with no chemicals?

Answer 1

It is likely rich enough, but you can always add more. Adding compost and well rotted manure to your soil will help to improve it.
