Abstract

AbstractThe experiment was set up in the forest ecosystem with diverse vegetation zones in the area of Istria and the Croatian Littoral. Research included the following systematic soil units: lithic lepto-sols, rendzic leptosols, rendzic leptosols - eroded, mollic leptosols, chromic cambisol and chromic luvisols. The average quantity of the forest litter in the studied systematic soil units reaches 13.36 t/ha (Tables 1-3). The “wealth” of organic matter in the studied soil units can be presented with the following series: chromic cambisols (CMx) > mollic leptosols (LPm), organogenic, rendzic leptosols (LPk) > lithic leptosols (LPq) > chromic cambisols (CMx) - Terra rossa, chromic luvi-sols (LVx) > rendzic leptosols (LPk) - eroded. As expected, the lowest value of total nitrogen was found in the lithic leptosols in relation to almost all the other soils, except when compared with chromic cambisol and rendzic leptosols (p ⋋ 0.05). The statistically justified higher values of the percentage share of P
