It has established a sampling grid with the size of the edge 50 x 50 m, comprising four sample for hectare, using gps system.
Unlike conventional management that is based on the average of observations in an area, precision agriculture uses a more detailed sampling,based on a sampling grid, which allows to represent in greater detail the reality of farming.
In each study areas a sampling grid was set, with six parallel tracks of 5 km long and arranged every 1 km in the northwest-southeast axis.
Geostatistics is used in study of spatial variability based on the estimation and identification of the interrelationships of the attributes studied, in space and time,allowing the optimization of sampling grid considering the spatial dependence between the observations.

Zuanoni in the xingu river basin. in the years that followed the work of the genus taxonomic revision, many collaborative projects and expeditions to the xingu were made,greatly increasing the sampling grid and the number of s. punctatissimus specimens, enabling a detailed analysis of morphological variations found along the river.
In this context the use soil sampling grids has the potential to be introduced in small farms in order to optimize the use of resources, since the conventional soil sampling process does not characterize the existing variability, so the use of inputs is done through the medium contents from the conventional sampling procedure.
