CURRENT RESEARCH
Dr. Sainju is currently working on the effects of tillage, crop rotation, crop diversity, cropping intensity, and cultural practices on soil aggregation, organic matter concentration, microbial activities, nitrogen mineralization, and carbon and nitrogen sequestration in dryland areas. He is also engaged in studying the effects of irrigation management, nitrogen fertilization rates, and cultural practices in nitrate-nitrogen movement in soil that affects water quality, soil organic matter level, and nitrogen mineralization in irrigated land. He is also involved in the development of methodology for determination of soil aggregation for dryland and irrigated areas and extraction method for determining ammonium and nitrate-nitrogen concentrations in the soils of various textures amended with or without plant residue.
ACCOMPLISHMENTS
Dr. Sainju has conducted research on soil and crop management practices, crop nutrition, soil fertility, soil biochemistry, and rhizosphere dynamics for efficient nitrogen uptake and reduced nitrogen leaching, carbon and nitrogen sequestration, improved soil and water qualities, and sustainable crop production. His areas of expertise include soil carbon and nitrogen cycling, nitrogen management, fertilizer use, soil organic matter and biochemical properties, root growth, nutrient uptake, and crop production. During his eight years of working on the long-term effects of tillage, cover crops, and nitrogen fertilization on crop production, carbon sequestration in plant and soil, soil nitrogen fertility, microbial activities, and nitrogen leaching at Fort Valley State University, he developed a management practice consisting of conservation tillage, cover cropping, and nitrogen rate that sustains crop production, improves soil and water qualities, and reduces the rate of nitrogen fertilization as compared with the conventional practice. He has authored and co-authored 30 research and Extension publications on soil organic matter dynamics, nitrogen management, root growth, waste management, and crop production.
