Abstract:

Quota-based fertilization is a crucial measure for improving soil quality and ensuring food security. Under the policy backdrop of reducing fertilizer usage and promoting agricultural green development, the systematic exploration of the impact and inherent regulatory mechanisms of quota-based fertilization on soil and the ecological environment, as well as the summary of key technologies for protecting and enhancing cultivated land quality, can contribute to an objective evaluation and comprehensive understanding of the significant role of quota-based fertilization in improving cultivated land quality. This article reviewed the connotation and policy evolution of quota-based fertilization, along with its technological innovations. It also summarized the effects and regulatory mechanisms of quota-based fertilization on key indicators of soil quality, discussed how to enhance soil quality through quota-based fertilization measures, and proposed future research priorities for quota-based fertilization in soil quality protection, to provide references for further promoting the improvement of cultivated land quality at a deeper level.

Key words: quota-based fertilization, chemical fertilizer reduction, soil quality, soil health, food security
