Bentonite is widely used in industrial wastewater treatment because of its large reserves, wide distribution and excellent physical and chemical properties. However, natural bentonite and modified bentonite are directly used as adsorbents, which have such defects as small adsorption capacity and difficult solid-liquid separation. In order to make up for these …

Treatments included six rates of bentonite amendments (0, 6, 12, 18, 24 and 30 Mg ha −1) applied only in 2011, and a control with no bentonite amendment. Application of bentonite significantly increased soil microbial biomass parameters (MBC, MBN and MBP), soil organic C, and total N and total P over the five-year experimental period.
