Current research and/or projects

1. Effect of combined application of papermill biosolids and biochar on the mycorhization, crop nutrition and grain yield of corn and soybean

2. Long-term assessment of 9-yr repeated applications of papermill biosolids and alkaline residuals on the crop yield and quality and the soil properties

3. Long-term effect of soil tillage and N and P fertilization in a corn-soybean rotation
