Soil health in the vicinity of Zagreb landfill

Soil health and agricultural production were analyzed in 2012 and 2013 in the area around municipal waste disposal site Prudinec Jakusevec, Zagreb, Croatia. Within the land use analysis, in the radius of about 2 km, based on photo interpretation, and Corine Land Cover 2000 classification, 13 different classes on total area of 3749 .7 ha were diagnosed. Thirteen land use classes were thematically grouped into four major groups: water: 4.97%, forest: 1.59 %, agricultural land: 48.27 %, and city: 45.17 %. It is important to emphasize that agriculture (1810.1 ha) as a branch in the urban area of Zagreb has a very great importance, regardless of the proximity of the landfill. According to the General Soil Map of Croatia (1:50 000) in the investigated area in landfill surroundings, two soil units were classified: calcareous alluvial sandy loam soils and alluvial carbonate, sometimes poorly colluvial loam soils. In the evaluation of soil health 24 soil surface (0-30 cm) samples were taken and analyzed in the vicinity of landfill (agriculture production - 17, grazing meadow - 2, cover soil - 2, inundation of Sava river - 3). Soil pH, EC, organic matter, texture, plant available P and K, carbonate content, total C, N and S, the content of fluoride, chloride, nitrite, nitrate, sulfate, phosphate, sodium, ammonium, potassium, calcium, and total Cu, Zn, Cr, Ni, Pb, Cd, Hg, As, Co and Mo were determined. Results showed that soils are weakly alkaline (~ 7.5) and medium to strong carbonated, with great differences in OM content (1.3 – 10.1) % and texture ( sand: 8-50 % ; silt: 43 -74 % and clay: 7-23 %) despite relatively short distance between locations. In some soil samples concentrations of Ni, Zn, Hg, Pb and Cd were higher than natural.
