Soil amendments are important for improving and maintaining soil productivity. AFSRC has a long history of studying soil amendments to overcome soil acidity problems. Mojtaba Zaifnejad (formerly, collaborator with Virginia Polytechnic and State University) and Barry Harter (Biological Science Technician) use a capacitance probe to measure soil water levels in a study of coal combustion byproducts as a soil amendment.
