How do shallow-rooted plants without tap roots manage to be dynamic accumulators?

I have a question.  How do shallow rooted plants (such as woodland strawberry and yarrow)  dynamic accumulators?  I thought that in order to accumulate nutrients, you had to have a taproot.

I don't think they all have to have taproots, although many do. Others may depend on an extensive root system that can accumulate more nutrients than others.  The root system of the woodland strawberry forms a symbiotic relationship with endomycorrhizal bacteria, and that may have something to do with it, too.  I'm not educated enough about it to know for certain.

i don't know the answer either, however I have read over and over that yarrow is a great soil buildler, and I'm not exactly sure why, but I have read it.

I think that deep rooting is a common feature of most dynamic accumulators, however this isn't always the case. Commonly, the plants are drawing minerals from the subsoil and concentrating them in their bodies. It is possible that plants are drawing in the nutrients they concentrate from the surface as well.

If anyone wants see a grand list of dynamic accumulators and what they accumulate, check out http://oregonbd.org/Class/accum.htm.

The hairs on the roots take nutrients from the fungi. The fungi get nutrients from breaking down rocks and dead plant material
