• 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.

• Spatial Distribution of Some Soil Elements in the Al-Kawtha Project in Iraq (2026) · International Journal of Life Science and Agriculture Research · doi

  There is a lack of research on the spatial distribution of major soil nutrients in the Al-Kawtha Agricultural Project. There is a need to identify sustainable management strategies to preserve soil fertility and productivity in semi-arid regions.

• Georeferenced analysis of surface soil (0–15 cm) macro and micronutrient distribution and status at the Agricultural Research Station, Karimnagar, Telangana (2026) · Plant Science Today · doi

  The study identifies a gap in the current understanding of soil fertility heterogeneity at micro-spatial scales. There is a need for site-specific nutrient management strategies in intensively cultivated systems. The research highlights the importance of considering micronutrient availability in soil fertility management.

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

  The study identifies a gap in the understanding of residue-quality–driven fertility pathways in semi-arid agroecosystems. The study notes that the effect of different plant residue types on soil fertility and nutrient dynamics is not well understood.
