The analysis of land use change is essential to understand the current condition and prospect the soil state soil whenever it can generate impacts in soil conditions, but these responses are not well characterized under dry tropical climate conditions. Using a stratified random sampling, samples (n = 5) at two soil depths and three types of land use (natural, agricultural and green zones) were collected in Santa Marta, Colombia, to evaluate the land use effects on some physical and chemical soil properties. The results showed significant changes in carbon content, total nitrogen, humidity temperature, bulk density total porosity and CEC. The principal components analysis differed edaphic characteristics by use, where the higher contents carbon was associated to green areas, the porosity to forest area and the highest values in conductivity, pH and humidity were found in the agricultural area, thus, the soil use influences physical and chemical characteristics, so it is necessary to follow up for a sustainable soil management.

Palabras clave : Land use; dry tropical climate; forest; green zones; and agricultural systems.
