para plantas. Estas analises
podem ser realizadas por
métodos como o da resina
de troca iônica. Todas
as metodologias usadas
requerem etapas de
amostragem, tratamentos,
e envio das amostras a um
laboratório que faça as
análises pertinentes. Neste
trabalho desenvolveu-se
um filtro que ao ser colocado
no solo atuou como
trocador iônico, permitido
que após a sua remoção
do solo a analise seja realizada,
sem que ocorra
o envio ou tratamentos
de amostras do solo. O
material foi confeccionado
utilizando fibras vegetais
previamente tratadas, e
modeladas em formato
que permitam a sua inserção
no solo.

ABSTRACT
Soil is an environment
formed by materials of
mineral and organic origin,
pore water and air. The
mineral part is made up of
rock fragments of different
minerals, with varying shapes
and sizes. Organic matter
originates from plant
and animal remains in
varying degrees of decomposition.
The water present
in the soil is responsible
for dissolving and making
metallic elements available,
and for this reason it is
called soil solution. In this
complex environment that
is the soil, different types
of plants are cultivated,
and they use the nutrients
available in the soil solution
for their complete development.
Each plant needs
different amounts of these
nutrients, and in order to
know the content of these
elements in the soil, it is
analyzed. The analysis is
divided into numerous
steps and aspects related to
plant nutrition. Macro and
micronutrients are evaluated
for their total content
and availability for plants.
These analyzes can be
carried out using methods
such as ion exchange resin.
All methodologies used
require sampling steps,
treatments, and sending
the samples to a laboratory
that carries out the relevant
analyses. In this work, a filter
was developed that, when
placed in the soil, acted as
an ion exchanger, allowing
analysis to be carried out
after its removal from the
soil, without sending or
treating soil samples. The
material was made using
previously treated vegetable
fibers, and shaped into
a shape that allows it to be
inserted into the soil.
