Sistema de informação para filtragem de dados utilizados com penetrômetro de placa na determinação da compactação do solo.

Abstract

The compacting of the soil is a harmful phenomenon to the agricultural sector for modifying its physics/chemistries property, causing influence negative on the productivity. The equipment used – as penetrometer of plate – with the purpose to quantify the levels of compacting of the soil, intends to supply a lot of information in the control of this phenomenon. With the helping of an information system, can be developed a prototype able to read all the data deriving of an assay with penetrometer and quickly to carry out a standardized filtering of the data, by determinated parameters before tests, also allowing the immediate construction of the desired compression lines. The analysis, carried through “in situ”, thus excusing, procedures laboratories allows to greater agility in the taking of decisions to the agriculturist, how much the correct use of the available machine. The development of software was able to prove the efficiency of penetrometer of plate in the determination of soil compaction, through uniaxiais pressures and to strengthen that the carried through extreme traffic “in situ”, is one of the main causes of soil compaction.
