Mabel Ifeoma Onwuka

Professor Mabel Ifeoma Onwuka is a Soil Scientist specializing in Soil Chemistry at Michael Okpara University of Agriculture, Umudike, Nigeria. Her research focuses on soil health restoration, soil acidity management, soil carbon management, agricultural biomass valorization, circular economy approaches in agriculture, soil fertility management, nutrient dynamics, climate-smart agriculture, ecosystem restoration, and the sustainable management of tropical agricultural systems. She is particularly interested in developing nature-based, resource-efficient, and low-cost solutions that transform agricultural waste into valuable soil amendments, including biochar, compost, and liquid organic fertilizers, to improve soil productivity, restore degraded soils, and enhance resilience to climate change. Her work integrates laboratory and field research with community engagement to advance sustainable agriculture, food security, environmental sustainability, and improved livelihoods for smallholder farmers, particularly women and youth across sub-Saharan Africa.
