Fig. 2. X-ray diffractograms (Co K ${alpha}$ , values of reflection in nm) of the oriented Mg-saturated <2-µm fraction (Mg N), ethylene-glycol-treated Mg-saturated <2-µm fraction (Mg EG) and 520°C heated K-saturated <2-µm fraction (K 520°C) in the tilled topsoil (Ap horizon), 25- to 35-cm subsoil (E horizon), and 40- to 50-cm subsoil (Bt horizon).
