How much biodiversity using dynamic accumulators?

Hey everyone, new here.

I've been reading here and elsewhere about dynamic accumulators. I want to grow some to use as mulch/top dressing/soil amending on other plants I'm growing. I have limited space in which to plant the dynamic accumulators- room for about 40 plants. My question if anyone can answer it- would it be better to grow the widest range of dynamic accumulator plants possible for greater biodiversity, but meaning each growing plant I use it on will have less nutrients from each dynamic accumulator used; OR would it be better to grow a smaller range of dynamic accumulators so that each growing plant I use it on will get a higher nutrient count from each dynamic accumulator, but less of a biodiversity range?

Sorry if this seems confusing.

Thanks anyone for any feedback.

When there is any doubt, I would always go for the greater amount of diversity.

Comfrey. Personally that's what I'd do. Perhaps a couple others in the corner?

First of all Keith, welcome to Permies!

I know when I first ventured into permaculture, I brought with me many ideas I learned from organic (but still conventional) gardening. One of those ideas was that plants in the same area compete for water and nutrients, so the conclusion is that it's best to keep variety to a minimum. Then came permaculture with its multilayered food forests and its plant guilds and choirs. That was a revelation in thinking because it wasn't what I learned first. But the more I study soil science, the more I understand that soil microorganisms are the key to healthy soil and nutritious vegetables and fruits, and power-packed dynamic accumulators. These soil organisms thrive on diversity! Jon Stika's A Soil Owner's Manual (Permies book review here) helped me understand that weeds (the stuff we don't want) are nature's way of trying to provide the diversity soil organisms need. So yes, your instincts are correct - work toward the greatest biodiversity you can!
