The aim of our study was to investigate long-term effects of wood ash fertilization, given together with nitrogen, on soil chemical properties, soil microbiological processes related to C and N cycling, and tree growth. The study was carried out in a 31-year-old Scots pine stand and in a 45-year-old Norway spruce stand 15 years after application. The treatments were (1) a control with no ash or nutrient addition, (2) wood ash + N (WAN), and (3) a stand-specific fertilization (SSF) formulated on… CONTINUE READING
