Analysis of soil fertilization practices by market gardeners and their perception of the use of compost based on mango residues in the commune of Korhogo, northern Ivory Coast

Market gardening is a key source of income and food security for households in Korhogo. With urban expansion, pressure on soils has increased, leading to declining fertility and threatening production sustainability. This study aimed to assess current fertilization practices and explore the potential of mango residue compost as a local alternative. A survey of 72 producers across six urban and peri-urban sites—mostly women—focused on crops, fertilizer types, application methods, and constraints. Results show that 93% use chemical fertilizers, mainly NPK (88%), while only 28% use organic inputs and less than 10% use compost. Microdose application is common, helping reduce leaching. Major constraints include poor soils, irregular rainfall, and pests. Despite limited adoption, producers expressed strong interest in mango compost due to its local availability. Barriers include lack of information, technical skills, and equipment. These findings highlight the need for simple, adapted solutions. Developing a local composting system based on mango residues could improve soil health and reduce reliance on chemical inputs.
