Educational record

Area of Expertise
Soil Acidity Soil Biochemistry Soil Health Restoration Organic Wastes Re-cycling Soil and Water Conservation Sustainable Tropical Soil Management and Gender -Mainstreaming Soil Organic Matter Soil Fertility and Productivity Carbon Sequestration Rural, Peri-Urban and Urban gardening
Research Focus
My research seeks to have a better understanding of the core principles of soil reaction and its role in soil chemical properties especially in the Tropics. I am particularly concern with the agricultural practices that reduce soil acidity’s effect for the improvement of soil nutrients availability such as nitrogen and phosphorus, soil organisms’ activities and organic matter build- up. This research area is significant, relevant and also a panacea in combating the chemical, biological and physical land degradation in order to restore soil health, improve soil fertility and productivity, ensure food security at local, regional and global level.
The conversion of safe, decomposable agricultural and municipal wastes as a method of re- cycling has been the main thrust of my research. Through this process rich and nutritive compost, ash, biochar that increase soil nutrients, sequestrate carbon to reduce climate change and stabilize soil particles, have been developed.
Most recently, my interest and efforts have been geared towards mainstreaming gender in waste conversion, sustainable soil management and conservation, as well as rural, peri-urban and urban vegetable gardening to achieve healthy nutrition and zero hunger.

Teaching Focus
I aim at producing students who will have great passion for science and become reputable leaders, in their chosen careers. I adopt the approach of creating enabling classroom, laboratory and field environments that motivate, encourage and provide opportunities for the students to become result oriented, team players, critical thinkers and problem solvers of soil and environmental related issues. My teaching involves using stimulating theories and practical sessions to explain factors affecting soil reactions and its amelioration, nutrient cycling, nutrient leaching, organic matter dynamics, soil microbes activities, soil water movement and uptake by plants, processes that escalate soil degradation and amelioration , heavy metals contamination and remediation, processes of compost, biochar and ash production. My focus is also on carbon sequestration through biochar, land use changes and effect on soil productivity and food security, soil and water conservation techniques in improving soil fertility and productivity, laboratory and field analyses of soil nutrients to detect any change in the nutrient status of the soil.

Profile Summary
Professor Mabel Ifeoma Onwuka is actively involved in teaching, research and community development. Her teaching styles, leadership skills and lively classes make her students develop interest in topics in soil chemistry, biochemistry, microbiology and environmental chemistry that she teaches. Through her research that spans from soil acidity amelioration, soil health restoration, organic waste re-cycling, soil fertility and productivity improvement among others, she has been able to proffer solutions to some of the soil related issues in her region. Her active involvement in Community development through her voluntary works has given her opportunities to enhance the the lives of some resource poor farmers in some communities.
Her achievements and contributions to the society have been featured in the following:
