| Abstract | The aim of the study was to evaluate selected changes of the quality of light soil in a layer of 0-90 cm, under cultivation of willow coppice (Salix viminalis) in the 4-year cycle, due to fertilization with compost from municipal sewage sludge and mineral fertilizers. The experiment was carried out in 2006-2009 on the experimental field of Koszalin University of Technology in Kosciernica, Polanow municipality (16 degrees 24'N and 54 degrees 8'E). The experiment was established on light soil of class IVb-V, of good rye complex, and granulometric composition of light loamy sand to a depth of 100 cm and light loam below 100 cm. <br> <br>The experiment factors were: fertilization (I) - (a) objects without fertilization, (b) fertilized with compost from municipal sewage sludge (10 t.ha(-1) d.m.), (c) fertilized with compost from municipal sewage sludge (10 t.ha(-1) d.m.) and mineral nitrogen in the amount of 90 kg N.ha(-1), and (d) fertilized with compost from municipal sewage sludge (10 t.ha(-1) d.m.) and mineral nitrogen in the amount of 180 kg N.ha(-1) and clones of willow (II) - 1047, 1054, 1023, 1013, 1052, 1047D, 1056, 1033 and 1018. Compost characterized by: pH(KCl) - 6.63, dry mass content - 68.42%, and content in dry mass was as follows: organic matter - 39.06%, N - 1.75%, P - 1.60%, K - 0.112%, Ca - 3,426% and Mg - 0.325%. Compost was applied in the spring of 2006, and nitrogen fertilizer was applied each year before start of vegetation of willow in the years 2006-2009. The field area was 34.5 m2, it was planted 120 cuttings (34782) pieces.ha(-1). Each year, after vegetation period of willow soil samples were taken from each plot from three depths: 0-30 cm, 31-60 cm, 61-90 cm. Analysis of soil after first (2006), second (2007), third (2008) and fourth year (2009) the willow vegetation periods included assessment of the content of dry matter, humus and organic carbon, total, ammonium, nitrate and mineral nitrogen and soil pH. Studies show that during years of shoots regrowth of willow content of total, nitrate and mineral nitrogen decreased in soil and content of ammonium nitrogen, organic carbon and humus increased. Fertilization of willow with compost from municipal sewage sludge caused increase of the content of humus and organic carbon in soil and raised soil pH. It did not affect the content of mineral nitrogen forms. Fertilization of willow with mineral nitrogen caused increase of nitrate and mineral nitrogen content in the soil, and decrease of soil pH, and did not affect the content of humus, organic carbon, total and ammonium nitrogen. |
