Avaliação do desempenho do programa CR Campeiro 7 para análise das propriedades químicas do solo e mapas de produtividade

Abstract

This work is to present and discuss the Precision Farming in a simple way through the routines of the precision farming into the system Campeiro CR-7 and its performance in order to analyze the spatial variability of soil properties and productivity. Chapter I The Loop Sampling, provides a tutorial on developing a sampling plan for spatial assessment of physic-chemical properties of soil by means of geostatistical techniques, the sampling plan can contribute significantly to reducing the cost of collection of samples as well as quality of these samples. Chapter II Map of Fertility analyzes a tool that assists the user in the classification of levels of soil fertility, and the result presented in map form, where the final map is a cross between a map that contains phosphorus in the soil and map showing the clay making the recommendation to apply phosphorus fertilizer supplier to more precise areas where there is more than one class of clay. Chapter III Productivity Map filtering is performed on the data collection, making it possible to make a map of productivity consistent with the reality of the field with a greater reliability of the data, providing information relevant to agricultural management.
