Two prairie soils were examined after 20‐years of occupancy by four tree species to determine what alterations had occurred. Bulk density, exchangeable bases, pH, and organic carbon had not changed in the 0 to 10‐cm soil layer. Red pine ( Pinus resinosa ) and Japanese larch ( Larix leptolepis ) caused significant increases in total N and a change in N form. Tulip tree ( Liriodendron tulipifera ) caused a significant change in N form while basswood ( Tilia americana ) caused no significant alteration. From this we conclude that alteration in soil N form is one of the first changes to occur following afforestation.
