Definition of management zones for zinc levels in function of the use of soil and landscape position

Zinc (Zn) is one of the most important elements on plant nutrition.  Zinc participates in a large number of enzymes, and its basic functions in the plant are related to the metabolism of carbohydrates, proteins and phosphates. Furthermore, Zn acts in the formation of auxins, RNA, and ribosomes (BORKERT, 1989). This work aimed at evaluating the Zn contents in soils from Inconfidentes region, Minas Gerais State, Brazil. The tool used to conduct this study was the geostatistical analysis with the aid package geoR (RIBEIRO JR. E DIGGLE, 2001) R software (R CORE TEAM, 2016). From the analysis, it was possible to conclude higher soil zinc levels were found in regions with higher elevation as well higher latitude and longitude
