Abstract:Talno organsko snov (TOS) sestavljajo živi organizmi, odmrli rastlinski in živalski ostanki na različnih stopnjah razkroja ter humus. TOS izboljšuje rodovitnost tal v smislu hranilne vrednosti in vodno-zračnega režima. Namen raziskave je preučiti vpliv konvencionalnega (KON), integriranega (INT), ekološkega (EKO) in biodinamičnega (BD) pridelovalnega sistema na vsebnost organskega ogljika (OC), humina (HN) in črnega ogljika (BC) v tleh. Vzorce tal (0–20 cm) smo odvzeli v letu 2021 s poskusnega polja UKC Pohorski dvor. Vsebnost OC, HN in BC smo določili po oksidaciji organske snovi s K2Cr2O7 v kislem mediju. Povprečna vsebnost OC je bila v EKO (16,2 g/kg) statistično značilno višja v primerjavi s KON (15,3 g/kg) in kontrolo (15,3 g/kg). V vsebnosti HN med pridelovalnimi sistemi ni bilo značilnih razlik, kar je verjetno posledica velike variabilnosti znotraj KON in INT. Povprečna vsebnost HN je bila najnižja v INT (9,5 g/kg) in najvišja v EKO (11,6 g/kg). Povprečna vsebnost BC je bila statistično značilno višja v kontroli (3,3 g/kg) v primerjavi s KON (2,8 g/kg), INT (2,8 g/kg), EKO (2,9 g/kg) in BD (3,0 g/kg). Rezultati kažejo, da dolgoročna trajnostna raba obdelovalnih površin poveča vsebnost OC in HN v tleh, kar prispeva k boljši kakovosti tal in dolgoročni rodovitnosti.

Title:Production system effect on soil organic matter content and composition
Abstract:Soil organic matter (SOM) consists of living organisms, dead plant and animal remains and humus. SOM improves soil fertility in terms of nutrient value and water-air balance. The aim of the study was to investigate the effects of conventional (CON), integrated (INT), organic (ORG) and biodynamic (BD) production systems on the content of organic carbon (OC), humin (HN) and black carbon (BC) in the soil. Soil samples (0–20 cm) were taken from an UKC Pohorski dvor trial field in 2021. The contents of OC, HN and BC were determined by oxidizing organic matter with K₂Cr₂O₇ in an acidic medium. The average OC content was statistically significantly higher in ORG production system (16,2 g/kg) compared to the CON (15,3 g/kg) and the control (15,3 g/kg). There were no significant differences in HN content between the production systems, which is probably due to the high variability within the CON and INT production systems. The average HN content was lowest in the INT system (9.5 g/kg) and highest in the ORG system (11.6 g/kg). The average BC content was statistically significantly higher in the control (3.3 g/kg) compared to CON (2,8 g/kg), INT (2,8 g/kg), ORG (2,9 g/kg) and BD (3,0 g/kg). The results indicate that long-term sustainable management of arable land contributes to OC and HN content in the soil, leading to improved soil quality and long-term fertility.
