Spatial heterogeneity of soil properties of recreational areas of Volgograd

The article presents the developed soil maps and of spatial variability properties (pH, total salt carbonate content, organic carbon, density) in some recreational areas Volgograd. anthropogenic soils studied include various urbostratozems (Urbic Technosols (Transportic)), Ekranic (Transportic), as well quasizems (Phaeozems (Tehnic)), among agrogenic ones – accumulation-carbonate agrozems (Cambisols (Aric, Protocalcic). Natural are represented by light dark humus soils, chestnut solonetz, stratozems psammozems. According to data isolinear mapping, it was found that acid-alkaline green zones vary from slightly alkaline depending on horizon load. mapping did not reveal salinization upper 0–30 cm layer. Values carbon greatly (1–10%) conditioned presence or absence meliorative artificial layers, character territory use. content calcium carbonates 30 is small varies 0.7 5%. It established physical (density) directly depend level load, increasing footpaths lawns. Spatial assessment urban important for identifying with an excess contrary low certain chemical indicators planning landscaping gardening areas.
