Concentration, Translocation, and Balance of Phosphorous in Grassland Ecosystems of Semidesert Landscapes in the Northwestern Caspian Sea Regions

— The paper presents findings of research on the accumulation and translocation of phytomass by blocks of plant matter, as well as the concentration, stock, and balance of phosphorous. The research was conducted in grassland ecosystems on light chestnut and meadow-chestnut soils and typical solonchak, which occupy the major part of the Northwestern Caspian Sea region.
