• Residue Biochemical Identity Regulates Early Soil Fertility Recovery in Semi-Arid Agroecosystems of Erbil, Kurdistan Region, Iraq (2026) · Iraqi Journal of Industrial Research · doi

  Future studies could evaluate the long-term effects of plant residues on soil fertility and nutrient dynamics. The study's findings could be used to develop and test new strategies for improving soil quality in semi-arid agroecosystems. Further research could investigate the potential for using plant residues in other environments and agricultural systems.
