ABSTRACT
Background: Soil fertility decrease is a major concern in global agriculture and particularly in tropical areas in general and particulary in the northen part of Cameroon where the population is growing faster than the food production. Garoua 3 subdivision is an important agricultural zone of Garoua in North region. It is intensely exploited for the production of various food products like corns, groundnuts and many other crops. This is the main cause of the decline of soil fertility in this area. Objective: determination of the fertility state of agricultural soils of Garoua 3 subdivision. Methods: Three villages were chosen and sixteen samples were collected per village by using an auger, and according to the type of speculation, then physico-chemical properties of each sample were analysed and compared with reference values of fertility. Results: pH and mineral particle size of all the samples varies slightly (Sandy loam and pH comprise between 6,2 and 6,8) except the one of Babla 1 where texture is clayly. The soils of Djalingo 1 and 2 and Sanguere 1 have low organic matter content (˂1%) and those of Sanguere 1 and Babla 1 and 2 have moderate and high organic matter. Available phosphorus is almost low everywhere except the soils of Babla 2 (27,76cmol/Kg) and Sanguere 2 which have value comprise in interval of normal value (10,32cmol/Kg). Soils of Sanguere 2, Djalingo 2 and Babla 2 shows the values situated out of the normative range of Ca2+/Mg2+ ratio with respective values of 17; 13, 73; and 15,5 and soils of Sanguere 2, Djalingo 1 and 2, Babla 1 presents also the values out of normative range respectively 1,6; 1,45; 1,38 and 41,45. In all these localities, calcium remains the most dominant element with 72.2% of the exchangeable cations of all the soil. Babla1 registered he high value 6.56 meq /100g followed by the Babla2, 6.08 meq /100g and the lowest value of calcium were recorded to the Djalingo1 1.92 meq/100g. Concerning magnesium low value were registered in Sanguere2 0.152meq/100g. Where the high value is recorded to Babla1 4,56 meq/100g. Concerning the potassium, except Djalingo1 and the control which have registered a high value 0.25 meq/100g, the order rest have a same low value 0.11 meq/100g. The soil samples in Sanguere 2 have a low value of CEC 3.84 and the high is registrated in Babla1 60.8 cmol/Kg. The other ones have values comprise between 5 and 20 meq/100g. Whereas the high value of saturation rate is resgistrated in Sanguere1 soil samples 84,55 meq/100g and the low is obtained on the soil of Babla118.83. Conclusion: No sample has the optimal values for all the elements analysed and one can notice the low values of K+ for all the samples, but normal pH for all.
