More than one point.
First of all, forests have a layer of "litter" over the soil, mostly from
leaves but also containing other organic debris. This litter is continuously
breaking down and supplying nitrogen and other nutrients.
Second, forest surface soils are not particularly fertile, at least not as
fertile as we need in many of our garden areas. Especially in high rainfall
areas, much of the nutrients are either washed away or leached deep into the
soil (trees, of course, have no problem accessing these deep nutrients).
Third, many of the varieties of plants we grow are not the "natural" species
but highly bred varieties, and in breeding we sometimes have selected for
those needing extra fertility, even while concentrating on other
characteristics.
Fourth.... but that's enough for now.
