20.500.12556/RUL-179990 Tillage intensity shapes soil carbon stabilization pathways differently in contrasting soil textures 11-year field experiments Soil texture-dependent responses and time-scales of soil quality change, especially soil carbon, remain poorly understood. We addressed this gap using a dual time-scale design of long-term field experiments: 11 years of minimum (MT) versus ploughing tillage (CT), both followed by 5-year transitions to no-till (NT) in contrasting textures (loamy vs. silty clay) in NE Slovenia. In loamy soils, reduced tillage in the 0–10 cm layer increased soil organic carbon by 40–48%, dissolved organic carbon by 36–64%, permanganate oxidizable carbon by 67–84%, particulate organic carbon by 76–95%, and mineral-associated organic carbon (MAOC < 50 μm) by 28–34%. In silty clay soils, high clay content masked tillage effects, though labile pools showed stratification. MAOC < 20 μm remained stable across treatments and textures (2.0–2.5%), except under CT in loamy soil (1.73%), indicating enhanced decomposition. In loamy soils CT increased by 0.5–1 and 1–2 mm and decreased >20 mm and in silty clay soils increased <0.5, 1–2 and 2–4 mm aggregate formations. The MWD, GMD, Dm indices correlated strongly with C fractions, confirming physical protection mechanisms. Our dual time-scale approach reveals labile C pools and aggregate recovery respond within 5 years of NT, while texture modulates response magnitude and detectability. no-till transition long-term field experiments NE Slovenia organic carbon stabilization structure stability aggregation soil texture pedologija tekstura tal ohranitvena obdelava tal true false true Angleški jezik Slovenski jezik Članek v reviji 2026-02-27 11:26:02 2026-02-27 11:26:09 2026-02-28 04:43:37 0000-00-00 00:00:00 2026 0 0 21 str. iss. 3, art. 35 Vol. 10 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 631.4 2571-8789 10.3390/soilsystems10030035 269901059 soilsystems-10-00035.pdf soilsystems-10-00035.pdf 1 03AEEC577DA112692B691DDAE30C6534 df0e139c5273aba81bac35c4e20a18d079732715cef3a09da13142aa20ae82a2 c897efca-13c6-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=228978 https://www.mdpi.com/2571-8789/10/3/35 1 667bddc9-13c6-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=228977 Biotehniška fakulteta 0 0 0
