Johnson co-authors study

Alton B. Johnson

Dr. Alton B. Johnson, associate professor of soil physics and interim director of research at Alcorn State University, recently conducted research by using poultry litter to reduce the harmful effects of a commonly used herbicide in the environment. The study co-authored by Dr. Dennis E. Rowe, head of the Bio-statistics Unit at Mississippi State University, and Dr. Teferi Tsegaye, chair of the Department Plant, Soil and Environmental Sciences at Alabama A&M University, was published in 2011 issue of the Journal of Sustainable Watershed Science and Management.

Earlier work led by Johnson showed tremendous binding of this herbicide on soils with high organic matter content.
