Amostragem mínima em zonas de manejo para cálculo da média dos atributos químicos fósforo e potássio do solo

Abstract

The Supervised Curricular Internship (ESO) was performed through the analysis of data obtained by Nascimento (2015), Sousa (2015) and Mayrink et al (2019), with the general objective the determining of minimum number of samples to calculate the average of soil attributes in management zones of the study area; and with specific objectives the delimitation of management zones and verification of the influence of the number of samples on the representation of the management zone. Using tools that help the practice of precision agriculture such as QGIS and RStudio, it was inferred that there is a relationship between the minimum amount of samples to determine the mean of the P and K attributes in the soil, however, there was a discrepancy in the data referring to one of the management classes for each attribute, thus requiring another analysis to determine the results.
