Abstract
The study examines the influence of crop type, tillage systems and nitrogen fertilisation on humic carbon in Romania, using national data for 2005–2024 covering wheat, maize, sunflower and rapeseed. Carbon inputs from crop residues, roots and rhizodeposition were calculated in R using IPCC coefficients and then analysed in SPSS through factorial ANOVA, multiple regression and Pearson correlations. Crop type and tillage systems significantly affect humic carbon values, with the highest values found in oilseed crops and conservation systems using minimum tillage or no tillage. Nitrogen fertilisation shows the strongest positive effect among the quantitative factors examined. The conclusions support conservation soil management aligned with the CAP and GAEC standards, together with an assessment of economic performance and soil and climatic conditions.
