At the same time, more demonstration experiments and farmer-participated research should be carried out to improve everyone's acceptance and operational capabilities of scientific fertilization. In the future, research should focus more on fertilization optimization strategies in different agricultural ecological zones and planting patterns. Some smarter tools can be developed to combine real-time data of soil and crops to help farmers dynamically manage nutrient inputs. In addition, long-term research should be conducted to observe the sustained impact of integrated fertilization on soil health, crop yields and ecological environment. The mechanism of action of some environmentally friendly fertilizers also needs to be explored in depth, including their effects on nutrient flow, nutrient retention and crop quality. Through these efforts, the sustainability of cowpea cultivation will continue to improve, and farmers' income will be more stable and higher. Acknowledgments We would like to express our gratitude to the reviewers for their valuable feedback, which helped improve the manuscript.
