The dangers of planting conifers in pure stands under some circumstances are great enough to outweigh the economic desirability of pure forests. One such danger is the possibility of producing hardpans which will ultimately reduce the yields. The author points out the processes that are likely to bring this about. He suggests that the greater acidity of the percolating waters under a pure coniferous forest causes more rapid solution of the iron and aluminum compounds and their concentration in the subsoil to form hardpan than the less acid solutions percolating the soil under mixed forests.
