The Effect of nanoFe₃O₄ Particles on the Soil Urease and Catalase Activity

Abstract:

Effects of nanoFe₃O₄ particles with different content on the soil urease and catalase activities in pakchoi planting soil were analyzed by pot culture. The results showed that after nanoFe₃O₄ was added the soil urease and catalase activities were significantly inhibited. In the groups treated with 1%, 2% and 3% nanoFe₃O₄, the soil urease activity was significantly decreased by 13.9%25.2%33.6% , and the soil catalase activity was significantly decreased by 9.59%10.26%33.04% compared with the control group. It followed that nanoFe₃O₄ played an inhibiting role in the soil urease and catalase activities, and the higher content of nanoFe₃O₄ was, the inhibition was stronger.
