Résumé:
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.
