The usual methods of soil preparation in South-East European Countries are subsoiling, mechanical terracing, and mechanical or manual preparation of planting holes. On karst terrains in Croatia, afforestation by Pinus nigra and P. pinaster Aiton after subsoiling resulted in higher survival and growth rates compared to planting in pickaxe, and mechanically drilled holes (Tomašević 1994). Subsoiling with a bulldozer promoted higher survival of Pinus halepensis Miller (Barberá et al. 2005; Jelić 2012), Quercus ilex (Palacios et al. 2009, Jelić 2012), Cupressus sempervirens var. pyramidalis L., Pinus pinaster, and Pinus pinea L. (Jelić 2012) than holes made with an excavator in reforestation of a semiarid Mediterranean ecosystem.
