Criação e manipulação de mapas temáticos para agricultura de precisão utilizando a resistência do solo a penetração.

Abstract

The main objective of the Precision Agriculture is to diminish the production costs, to increase the efficiency, on the basis of the differentiated handling of areas in agriculture. Moreover, it’s techniques must be seen as a form of sustainable handling, in which the changes occur without damages for the natural reserves, at the same time where the damages are minimized. The data you show of this study had been gotten in an experimental area of the Center of Research Eloy Gomes (COODETEC) located in the Cascavel city, Paraná. The general objective of this work was to evaluate the behavior of a physical property of the soil (resistance of the soil penetration) of a lead agricultural area under the system of Precision Agriculture during the period five year, constructing thematic maps for this physical property and each year (five), analyzing the evolution of this parameter year by year. The gotten data had been interpolated using the mathematical method of interpolation of inverse of the square of the distance, generating the maps of resistance of the ground the penetration in the depths of 0-10 and 10-20cm. The behavior in the two depths had revealed similar.
