Urban agriculture is a response to food security in cities and it improves people's income. This agriculture is practiced on undeveloped land because of high land pressure. The aim of this work is to characterize the market gardening of the city of Korhogo. This study was carried out by means of a survey in order to know the socio-demographic profile of the producers and to characterize the market gardening operations of the sites studied. Soil characterization was carried out in order to determine soil physicochemical parameters. Surveys have shown that market gardening in the city of Korhogo is a predominantly female activity (98%). The use of mineral and organic fertilizers and pesticides is almost systematic on the plots and is intense on small ones. The analysis of the physicochemical parameters showed soils devoted to vegetable are predominantly sandy. They are low acid soils with pH ranging from 5.1 to 5.8. Nitrogen, organic carbon contents and exchangeable bases levels are very low. Only available phosphorus varying from 51 to 64 mg.kg-1had acceptable levels in these soils. The sand richness of the soil therefore favours the leaching of mineral elements, which leads to a decrease in soil fertility. This phenomenon leading farmers to disproportionately use chemical and organic fertilizers, could have an impact on market garden products’ quality.
