Soil Pollution Remediation and Case Study

Dr. Zhang’s research interests mainly focus on the finding of environment-friendly soil remediation techniques for the soil improvement and the mitigation of non-point pollution to surface- or ground-water. The research devotes to reducing the environmental footprint of agricultural production while satisfying increasing human food needs. Areas of current emphasis include: (1) Evaluating the potential of biochar soil amendments to impact soil fertility, nutrient retention, heavy metal immobilization, and greenhouse gas emissions; (2) Designing controlled-release fertilizer/pesticide and bio-fertilizer to improve soil nutrient cycling and decomposition and reduce environmental contamination in soil, water, and air; and (3) Understanding the interactions between minerals, microorganisms, plants, nutrients, and contaminants in natural and amended soils.
