The present study proposes the use of chemometric methods as an instrument for determining the most relevant parameters of fertility, nutrition, micronutrients and soil physics in agricultural areas. The study area is located in the northeast of the state of Pará, Brazil, your areas are evaluated, the first with Black Pepper (Piper nigrum L.) and Açaí (Euterpe oleoracea), a homogeneous plot was selected to carry out the collection of the soil, deformed and deformed samples, evaluating chemical, physical and water properties of both soils. The results were submitted to descriptive analysis, F test on the data and later to Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA), where it was possible to detect characteristic parameters for the area and thereby assist in management decision making.
