Vine Pruning-Derived Biochar for Agronomic Benefits

The agronomic benefits of biochar (BC) prepared by slow pyrolysis vine pruning residues, which are produced in large quantities Romania, were evaluated. Three soil types, i.e., slightly alkaline fluvisol (S1), acidic chernozem (S2), and strongly luvisol (S3), with mean values pH 7.99, 6.26, 5.40, amended BC at a volumetric ratio between 20/80. A greenhouse experiment was performed for 109 days to assess the effects amendment on bell pepper growth. following treatments applied: foliar fertilizer, BC, + fertilizer (using two concentrations solution), control. Strongly (pH 9.89 ± 0.01) had significant positive effect growth performance plants sown S3. height, collar diameter, number leaves, root volume grown BC-amended S3 without treatment significantly higher (13–72% 14–33%, respectively) than those non-amended treatment. This beneficial plant due changes properties. increased (up eight times) electrical conductivity, pH, soluble phosphorus, potassium, ammonium nitrogen S3, decreased its bulk density 51%, resulting improved water/nutrient uptake performance. no favourable parameters S1, S2.
