Description
  • Changes of soil phosphorus parameters (SPP) and soil organic matter (SOM) fractions were investigated in a Cambisol of medium-heavy texture. Soil sequential samples were taken from a minimum (MT) and conventional (CT) tilled field in Sitzenhof (Germany). For the CT soil, concentrations of available forms phosphorus (P) were stable to ~0.3-m depth, below which they rapidly decreased to relatively low values. In contrast, the decrease in the MT soil profile was gradual from the surface layer; available forms of P concentrations were higher and sorption index values were lower than in CT soil in corresponding depth. Concentrations of SOM fractions were higher in the MT than CT treatment soil along the whole soil profile, especially below the 0.3-m depth. The correlations between SPP and SOM fraction concentrations were closer in the MT than in the CT, particularly below 0.3-m depths.

  • Změny v parametrech půdního fosforu (SPP) a frakcích půdní organické hmoty (SOM) byly zkoumány ve středně těžké kambizemi. Série půdních vzorků byly odebrány z minimálního (MT) a konvenčního (CT) zpracování půdy v Sitzenhofu (Německo). Pro CT půdu byly koncentrace přístupných forem fosforu stálé do hloubky ~0,3 m, pod kterou se rapidně snižovaly k relativně nízkým hodnotám. Naopak, snížení v profilu půdy MT bylo postupné od povrchové vrstvy; koncentrace přístupných forem fosforu byly vyšší a hodnoty sorpčního indexu byly nižší než v CT půdě v odpovídajících hloubkách. Koncentrace frakcí SOM byly vyšší v MT než v CT zpracované půdě podél celého půdního profilu, zvláště pod hloubkou 0,3 m. Korelace mezi SPP a koncentracemi frakcí SOM byly těsnější v MT než v CT, zejména pod hloubkami 0,3 m. (cs)
