Abstract	The continuous and intensive agricultural exploration of Brazilian Tropical Semi-Árid soils, with the irrigated crops, has led to its degradation. To revert this process, the conservation of the soils and the productivity of the crops must be based on the covering of the soils using cultures or its residues, with the objective of: protecting it of rains of high intensity; increasing the infiltration and retention of water; increasing the organic matter; cycling nutrients; adding nitrogen; diminishing the oscillations of temperatures; diminishing the water evaporation of the from and salinization, besides raising the water availability for the plants. The objective of this study was to evaluate the potentiality of different cocktail vegetal to be used row spacing of mango, as one cropping practical for the management and conservation of the soils in cultivated areas with this economic species. The experiment was carried out at Estação Experimental da Embrapa Semi-Árido, with the intercropping vegetable cocktail, composing six treatments with different proportions of species of legumes and non-legumes.The evaluated parameters were production of dry matter and amount of organic matter and phosphorus. Vegetal Cocktail composed only by legumes, produced smaller amount of dry matter. The T3 and T4 presented largest amount of organic matter in the soil, differing significantly from the other treatments. In the T3 it was verified the largest amount of phosphorus in the depths 0-5 cm, not differing statistically from T4 and T5. Analysing the set of the evaluated parameters, treatment T3, with 75% of legumes and 25% of non-legumes, had the best performance, until the present time, adding the largest amount of organic matter and recycling the largest amount of phosphorus.
