This paper shows organic matter composition (humic acids, fulvic acids, humins) and fractions ofhumic (free and bounded with mobile R2O3 (HA1), bounded with Ca (HA2), and bounded with clay andstabile R2O3 (HA3)), and fulvo acids (free and bounded with mobile R2O3), bounded with HA1,bounded with HA2, and bounded with HA3), in Rendzina soils on different altitudes (151-1210 m),landforms (hilltop, flat or very gentle slope; foot slope, very gentle slope, south, southwest; slope 45-80º, south, southeast, southwest; slope 20-60º, north, northwest, northeast), and regions (Srem, west,central, east and southeast Serbia).Differences in temperature and water regimes of Rendzinas on various altitudes are not soprominent to have a significant impact on organic matter composition. Landform has more significantimpact, with average higher content of HA on slopes, and FA on flat positions, which could beattributed to reduced wetting of soils on slopes. Exposition had no significant impact on humuscomposition. Differences in soil moisture among regions are more pronounced than differences in soiltemperature.Differences in soil organic matter composition among Rendzinas from various regions aresmall and do not follow pattern of humidity change. Still, organic matter of Rendzina from mosthumid western region has the least favourable HA/FA ratio, while at the driest east and southeastregions content of humin is the greatest.

“…Our results showed that higher amounts of SOM were accumulated in the meadow than in the forest soils, which is consistent with the findings of Saviozzi et al (2001). In various regions of the world, however, higher C org contents, and thus SOM, have been reported in forest rather than meadow soils (Lemma et al 2006;Grunzweig et al 2007;Radmanović et al 2015). The discrepancies between these findings result from the different species and ages of the forests, which affect the amount of residues accumulating from the trees.…”

“…Tree species affect the quantity and quality of soil organic matter (SOM), and the properties and processes that determine soil fertility, such as pH, sorption complex composition, nutrient cycling and biological activity (Beas et al 2019). An important factor influencing the degree of such changes is the time passed after afforestation of grasslands (Radmanović et al 2015). As an indicator of the changes occurring in soils, including their fertility, an assessment of dehydrogenase activity (DHA) is often used because this represents the total soil microbial activity, and is rapidly reactive to any change (Salazar et al 2011;Veres et al 2013).…”

We aimed to evaluate the changes in grassland soils resulting from forest tree planting using two soil quality indices-a soil evaluation factor (SEF) and a soil quality index (SQI). We studied the impact of introducing forest trees (conifers, broadleaves or mixed) on natural meadows. We examined how the soil properties were affected by the tree species and their ages (25, 35 and 65 years old). Soil samples were collected from meadows and their adjacent forests, all situated within the boundaries of Krakow (Poland). Before the trees were planted, all areas were grassland, used for agricultural and recreational purposes. The soil samples taken from surface and subsurface horizons were analysed for pH, nutrients (C, N, P, K, Mg), humus compounds and dehydrogenase activity (DHA), and basic cations (Ca 2+ , Mg 2+ , K + , Na +). The introduction of trees on the grasslands lowered the pH and DHA activity, and impoverished the soils in nutrients. The impact on the soil properties of the tree species was more important than their age. The biggest negative changes were found in the soils covered by coniferous trees, in which the lowest values of SEF and SQI (respectively, 9 and 0.24) were recorded. The highest values of both soil quality indices (SEF-147, SQI-0.66) were observed in the meadow soils. The soils of a 35-year-old deciduous forest and a 65-year-old forest with deciduous and coniferous tree species had similar SEF and SQI values. The deciduous trees adapted better to the meadow soils than the conifers and, over time, an improvement in the soil properties occurred as a result of the accumulation of tree residues.
