Soils degradation is the factor that most affects the profitability of crop management on maize cultivation in Northern Cameroon and reduces the interest of their intensification. It is also affected by severe weather conditions but mainly by low valuation of agricultural products. Maize cultivation intensification is only possible with the help of a seasonal credit system to acquire inputs. The use of casual hired labor and an increase in the purchase price of corn are other conditions that will favor its implementation.
