Long-term changes of soil organic matter in the fallow experiment with different fertilization and tillage

Popis výsledku v původním jazyce

Soil organic matter under different tillage and fertilization system of the long-term bare fallow experiment established in 1958 in Prague was characterized in the period of 1972-2006. This experiment consists of seven variants [control (no tillage, no manuring); farmyard manure compost (FYM); 2FYM; mineral fertilization (NPK); 2NPK; reduced tillage, no fertilizers (RT) and conventional tillage, no fertilizers (CT)]. In 1989, regular manuring and tillage were terminated and since then only weeds have still been removed mechanically. Organic carbon content (Cox ) was analysed and the hydrophobic (A) and hydrophilic (B) functional groups were determined using Fourier-transform infrared (FTIR) spectroscopy. Soil wettability (A/B ratio) was assessed in theexperimental variants. Organic manuring (FYM and 2FYM plots) increased significantly Cox content and intensities of hydrophobic (A) functional groups in FTIR spectra as compared to the control variant. Highly significant positive correla
