Phosphorus content in sediment and eroded soils in the southeastern part of West Siberia

▶ Soils and sediment were analysed for TP, K2SO4-P and FPmin. ▶ Content of the TP and K2SO4-P in sediment was connected with the fine soil particles. ▶ Upper layer of eroded soils was enriched by Ca-P apatite type. ▶ Drift soil exhibited the maximum content of the TP and FPmin (mainly PI-PII fractions).
