摘要: The aim of this study has been to evaluate the effect sewage sludge and composted municipal waste on content various forms P in soil. experiment scheme: C, control; NPK; FYM; DGSS, dried granulated sludge; CSS, composed CSSS, straw; CMMW, mixed waste; CMGW, green waste. bound was determined fractions: F1, easily soluble; F2, exchangeable; F3, organic; F4, carbonate; F5, stable organic-mineral mineral bonds; F6, residual. NPK fertilisation as well soil with organic substances raised P-total F5 F6. highest amount phosphorus studied fraction F3 (phosphorus compounds) lowest F1 ionic form H2PO4- HPO42-). Composted straw introduced into increased readily soluble (F1), while reversed. enhancement matter (except CMGW) led a reduction F2 fraction. available by Egner-Riehm method depended C-organic, CEC Among fractions, most strongly correlated carbonate (F4) residual (F6) and, less strongly,
