A major reason given for the decline in per capita food production in Nigeria over the last two to three decades is the gradual decline in land productivity. Available information shows that in southern Nigeria, for example, there was recorded a consistent decline in yield per hectare of major food crops between 1995 and 2000. Evidence from the literature suggests that the main reason for this persistent decline in soil productivity is the perpetuation of unsustainable soil management practices by small food crop farmers that dominate the food production landscape in the country.
