The abstract mentions how it leads to longer roots ("produced longer root systems"), which is probably the explanation for all the properties (it can extract water from deeper soil, and it can extract more nutrients from the soil).

My concern is how many generations of crops can one have in such a field before it needs artificial replenishing in the ways we do not do today (see my longer comment elsewhere on the thread :)).
