The aim of this study is to evaluate the effects of the fertilizers on the efficiency of the soils and on the input of the maize. Some soils samples were collected in the 0-10 cm and on 10-20 cm depths on different sites where fertilizers were applied in the periurban area. The results showed some differences quite significant between the treatments which had been done. The treatment T2(household waste) showed the highest contents in total carbon (1.27%),in total azote (0.13%),in total potassium(5882 mg.kg-1 of soil),in total phosphorus (622mg.kg-1 of soil) and the higher pHwater(7.98%).The treatment T1 (Pig manure)showed the highest content in available phosphorus and the highest C:N ratio. No significant difference was noted between the C:N ratio. At last, the treatment T2 has obtained the highest output of grains and the highest average weight of 1,000 grains (respectively 5.35t.ha-1 and 278g) with a highly significant difference noted between these two variables. The organic fertilizers application in the soil can contribute to improve the chemical characteristics of the soil and to increase the output of the maize.
