The main purpose of the study was to chemically characterize the green areas of the Universidad Peruana Unión to determine the influence of the different types of water on the dynamics between receiving soil, biological support and chemical inputs. The parameters analyzed, compared and correlated from the extraction of soil samples were pH, Total Nitrogen, Organic Matter and Available Phosphorus. The univariate analysis of variance and Spearman's correlation coefficient were then used. The pH was the only significant parameter among the study areas, and high correlations were shown between Total Nitrogen, Organic Matter and Available Phosphorus. The type of irrigation water influenced the dynamic behavior of the green areas. Therefore, the study highlights to choose assertively the type of irrigation water, to manage both economic and sustainable water resources available (river water, groundwater and previously treated river water), to formulate, predict and accurately observe soil chemical dynamics and to evaluate extensive green areas of wild, forest, rural or agricultural nature in the immediate environment or integrated in the urban space according to the type of water used for irrigation.
