Resumen

The research seeks to determine the influence of the use systems of different ages on the quality of the soil in the Cora Cora sector, Luyando district, Leoncio Prado province, for which it formulated the specific objectives, determining the physical and chemical indicators, as well as the soil quality through the sustainable soil use sub-index (SUSS) and mapping its spatial distribution of soil in three use systems (agroforestry system, coca and forest). Soil sampling was carried out and the physical and chemical indicators were evaluated, in order to determine the quality of the soil using the SUSS methodology, to represent it on a plane. The results were that the physical indicators present textural classes of silty clay loam in the coca system and clay loam in the agroforestry and forest system, apparent density all are in an ideal range and favorable temperatures for the normal growth of the established systems; the chemical indicators present pH levels from strongly acidic to neutral, organic matter, nitrogen, phosphorus; potassium and cation exchange capacity in the soil are low in all systems. The quality of the soil in the agroforestry system presents a sensitive quality, while the coca and forest system present a poor quality. Cartographic the spatial distribution of soil quality in the three use systems in an area of 3.61 ha shows poor quality.
