Properties of the fluvisol soil in the middle Danube basin

The paper presents the properties of the fluvisol soil in the area of the middle flow of the Danube river. The granulometric composition of these soils varies widely, and the following texture classes are identified: sand, loamy sand, sandy loam, sandy clay loam, clay loam and clay. Based on the prevailing fractions of the test composition, the following forms of this soil are defined: sandy, sandyloamy, loamy and clay. The total porosity of the tested soil ranged from 46.98 to 52.49% on average. It can be concluded that, according to the average values of CaCO3, these soils are very carbonate, the reaction of these soils is low to medium alkaline, while the average humus content is in the range of 0.58 to 1.54%, and these are low humic soils. The average groundwater level for the studied soils was from 124 to 309 cm in depth with a variation of 120 to 144 cm. The tested soils in terms of their properties are favorable for intensive forest production and are very suitable for growing black poplar clones.
