Abstract

With the continuous impact of high-intensity agricultural development and climate change, the cultivated land in some parts of my country has shown a trend of impoverishment, such as low organic matter content, poor soil nutrients, and decreased microbial activity, which seriously restricts the sustainable development of agriculture. Starting from the causes of impoverished soil, this paper systematically sorted out its main characteristics and distribution patterns, and summarized the research progress and application effects of multifunctional organic fertilizers in improving soil fertility, improving soil structure, and enhancing biological activity. The key technical paths of multifunctional organic fertilizers, such as design concepts, raw material selection, functional microbial addition, and nutrient slow release, were analyzed in detail. At the same time, combined with actual application cases in typical regions, the improvement potential and promotion model of different types of impoverished cultivated land were discussed. Finally, the article puts forward the current problems and future development directions, in order to provide theoretical support and technical paths for improving the quality of impoverished cultivated land in my country.
