For the recovery of a soil, it is necessary to select and to identify suitable species to new soil conditions and, quickly, accelerate the structuring and formation of more superficial horizons of the soil. The experiment aimed to evaluate the development of some species and varieties of Pinus, aiming at detecting those that present the greatest potential for adaptation and recovery of degraded land in the savannah region, and for this, we evaluated the chemical conditions of the soil where they are  present. At 20 years after planting, we analyzed the silvicultural characteritics and the chemical properties of the soil. In each plot, deformed samples were collected in the layers of 0.0-0.10, 0.10-0.20, 0.20-0.40 and 0.40-0.60 m. The use of Pinus species in reclamation showed promising improving the chemical conditions of the soil layer from 0.00 to 0.10 m, highlighting the Pinus caribaea var. hondurensis to present a good growth combined their survival, which guarantees the coverage of the soil due to deposition of organic matter by increasing the sum of bases and cation exchange capacity. The species of Pinus are providing conditions for the increasing of the diversity of spontaneous species.
