| Description
| - V období let 1972 až 2004 byla u dlouhodobého úhorového pokusu s různým systémem orby a hnojení založeného v roce 1958 v Praze sledována půdní organická hmota. Tento pokus se skládá ze sedmi variant (kontrola (bez orby a hnojení); kompost (FYM); 2FYM; minerální hnojení (NPK); 2NPK; redukovaná orba (RT) a konvenční orba (CT)). V roce 1989 bylo pravidelné hnojení a orba ukončeno a od té doby je pokus udržován jako černý úhor. Ve vzorcích půd byl stanoven obsah organického uhlíku (Cox) a pomocí FTIR spektroskopie byly analyzovány hydrofobní (A) a hydrofilní (B) funkční skupiny spektra. U pokusných variant byl hodnocen index hydrofobicity (HI) a smáčivost půdy (poměr A/B). Byly nalezeny statisticky významné pozitivní korelace (r = 0.976; P < 0.05) mezi hydrofobními funkčními skupinami (Band A) a Cox, hydrofilní funkční skupiny (Band B) nekorelovaly s Cox. Po ukončení organického hnojení měla smáčivost půdy sklon k poklesu s tím, že hodnoty poměru A/B se signifikantně lišily v závislosti na dávkách apliko (cs)
- Soil organic matter under different tillage and fertilisation systems of long-term fallow experiment established in 1958 in Prague was characterised in period of 1972–2004. This experiment consists of seven variants (control (no tillage, no manuring); farmyard manure compost (FYM); 2FYM; mineral fertilisation (NPK); 2NPK; reduced tillage (RT), and conventional tillage (CT)). In 1989, regular manuring and tillage were terminated and since then the plots have been maintained bare. Organic carbon content (Cox) was analysed and the hydrophobic (A) and hydrophilic (B) functional groups were determined using Fourier-transform infrared (FTIR) spectroscopy. Hydrophobicity index (HI) and soil wettability (A/B ratio) were assessed in the experimental variants. A high significant positive correlation (r = 0.976; P < 0.05) was found, between hydrophobic functional groups (Band A) and Cox, hydrophilic functional groups (Band B) did not correlate with Cox. Soil wettability tended to decrease after the organic ma
