English abstract The creation of proper soil fertility is fundamental to the agroecological transition phase and guarantees the sustainability of organic agribusiness. In a randomized complete block design with a 3 x 2 factorial scheme with 1 additional treatment (control, without organic fertilizer), we tested three poultry litter rates (7, 14, and 21 Mg ha-1) at sowing or splitting between sowing (30%) and side-dressing (70%) for two summer corn whole-plant silage crops and for the soil chemical attributes. The splitting of the poultry litter rate during the rainy season preserves the soil K content, prevents the accumulation of soil P and increases the efficiency of the increasing yields of the organic whole-plant corn silage crop. The reapplication of pre-sowing poultry litter can lead to an accumulation of P and Ca in the soil but favors fresh matter and cob dry matter yields in the dry season. The splitting of the poultry litter rate for whole-plant corn silage can guarantee technical and environmental sustainability in rainy years, but on the other hand, the reapplication of this organic fertilizer only at pre-sowing can increase the fresh matter yield and protein quality of organic whole-plant corn silage cultivated in an Inceptisol in the dry season
