Research Professional

To assist the lead research scientist in studies related to use of fertilizing residuals (compost, papermill biosolids, alkaline residuals, biochar) in agriculture and of N and P fertilization for field crops.

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
