- 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.

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.

Abstract Although it is known that multiple interactions among plant functional traits, microbial properties, and abiotic soil parameters influence the nutrient turnover, the relative contribution of each of these groups of variables is poorly understood.
