MINERAL COMPOSITION OF HIGH BLUEBERRY LEAVES AND FRUITS DEPENDING ON SUBSTRATE TYPE USED FOR CULTIVATION

摘要: In 2004-2006, an experiment was established at the Experimental Station Rajkowo belonging to Agricultural University (West Pomeranian of Technology) in Szczecin. High blueberry bushes were planted alkaline reaction (pH 7.1) heavy soil using three different substrates. The trenches filled with peat, cocoa husk and sawdust. fertilization plants limited a sole nitrogen supply (30 kg N ha-1), because chemical analyses both substrates showed high and/or moderate content other nutrients. order decrease maintain peat sawdust, irrigated H 2 SO 4 acidified water up pH 2.5-3.5. bed prepared characterized by highest (23.8 mg 100 g -1 ), Zn (51.6 (5.0). On hand, sawdust substrate had lowest salinity (0.35 NaCl kg-1). Sawdust level Mn (56.5 kg-1) Cu (7.4 Ca (83 g-1), whereas, (0.87 ) (3.8). usage resulted (23.6), K (6.9 (104.5 cv.
