Soil Fertility Characterization Based on Present Weed Specie. In order to determine the soil fertility level using weed indicators, a study was conducted in 4 villages in northern Cameroon. It was based on farmers' interviews and fi eld surveys. It appears that the soil fertility status can be determined by using two groups of weeds: "guide" weeds, orienting the diagnosis according to their relative importance; "indicator" weeds, used to discriminate the two soil types (fertile/ degraded). Presence or absence of the identifi ed species allows farmers to determine whether the plot is fertile or degraded. He can then decide to use the fi eld or not.
