Copper (Cu) is a critical micronutrient for wheat (Triticum aestivum L.), essential growth and grain baking quality, yet its availability limited because Cu specifically adsorbed on colloids of highly weathered tropical soils like Oxisols. This study hypothesizes that Cu-doped biochar composites can outperform traditional fertilizers in improving use efficiency. Composites were synthesized from chicken manure (FCM), shrimp shells (FSC), sewage sludge (FSS), doped with copper sulfate (CuSO45H2O) or oxide (CuO), pyrolyzed at 300 °C 550 °C. The experimental design involved greenhouse trials two Oxisols (RYL DRL), assessing release kinetics, plant uptake, dry matter production. Fourier Transform Infrared Spectroscopy (FTIR) confirmed successful integration. Results revealed CSS/CS-5 (FSS + CuSO45H2O °C) improved uptake shoot biomass DRL soil, while CSC/CS-3 (FSC enhanced RYL soil. Peak varied by soil composite type, residual highest CuSO45H2O-treated soils. These findings demonstrate Cu–biochar composites, tailored to conditions, offer sustainable alternative mineral enhancing the nutrient yield.
