Recomendação de calagem através de amostragem georreferenciada comparando a aplicação: taxa fixa e variável

Abstract

This academic work has been done in the city of Lidianopolis-Pr, on the property of Pacheco’s family and it aims to analyze the technical and economic feasibility in the use of limestone application, through the recommendation, the variable rates in comparison to the fix rate, thereby seeking trace a comparative between both forms of corrective application. Georeferenced collect of soil were held to the sampling of areas and interpolated through a software, in this way creating the fertility map of the area and afterward the recommendations. The economic viability in use of variable tax regard to the fix tax is expressed with a few difference in values, but if compared to the long-term benefit and the use of correct quantity in soil is something that we must consider.
