The effects of amendments on cd and pb under different fertilizer application conditions.

ABSTRACT: Fertilizer application is a common agricultural practice that enhances soil fertility but can also increase heavy metal mobility in contaminated soils. This study used a pot experiment with four vegetables (water spinach, Chinese cabbage, lettuce, and garland chrysanthemum) to evaluate the impact of BC, ZE, and their combination (CO) on Cd and Pb levels under different fertilization schemes. Results showed that CO treatment significantly enhanced enzyme activities, increasing urease by 2.6-31.6% and catalase by 1.37-14.24% under varying fertilizer conditions. However, sucrase activity increased only with compound fertilizers. The use of compound fertilizers alone raised Cd and Pb levels in vegetable shoots by 0.65 mg·kg⁻¹ and 12.76 mg·kg⁻¹, respectively, while the CO amendment effectively
