Compost amendment to agricultural soils influences plant growth and soil quality by affecting activity of arbuscular mycorrhizal fungi (AMF) and composition of microbial community. We related the molecular composition of compost of different maturity added to soils to their effects on maize growth, N and P uptake, AMF root colonization and growth, and(More)
Four water extractable organic matter (WEOM) were obtained from composts made out of residues of: 1. artichoke (C-CYN), 2. artichoke/fennel (C-CYNF), 3. tomato/woodchips (C-TOM), 4. Municipal solid waste (C-MSW), and their bioactivity was tested for maize seed germination and maize seedling growth. The molecular properties of both original composts and(More)
Liquid-state 31P-NMR spectroscopy becomes progressively an important role for studying phosphorus (P) dynamics in soil. Soils of different origin and organic matter content were used to optimize sample preparation and re-dissolution procedures to improve characterization of P species in soil by 31P-NMR spectroscopy. The efficiency of P extraction from an(More)
