CARACTERIZAÇÃO QUALITATIVA DE SOLOS ATRAVÉS DE CROMATOGRAFIA DE PFEIFFER EM AGROECOSSISTEMAS
O desenvolvimento da tecnologia
de estudo da qualidade do solo tais como a
Cromatografia de Pfeiffer se torna de grande
utilidade para os agroecossistemas manejados
de acordo com os princípios agroecológicos, por
ser de fácil entendimento, baixo custo e abordar
aspectos relativos a movimentação da vida do
solo. O objeto da proposta foi avaliar o uso da
Cromatografia do solo de Pfeiffer como indicadora
da qualidade dos solos de agroecossistemas
de base familiar e de um ecossistema florestal.
O trabalho foi realizado no município de
Solânea-PB, em seis agroecossistemas de
base familiar e no ecossistema floresta. Foram
coletadas em campo sete amostras composta
por solos de 0 à 15 cm e levadas ao laboratório
de Agroecologia (ASDA) para realização da
prática da Cromatografia. Para a análise das
Cromatografias, foram utilizadas categorias
qualitativas observando suas zonas, cores e
formas, expressas através de semáforos com
cores distintas e legendas. Os resultados das
avaliações cromatográficas indicam que houve
diferenças de qualidade entre os solos estudados
dos agroecossistemas, sendo classificados na
categoria suficiente com os semáforos apontando
cor predominantemente amarela variando entre
o vermelho e verde. Somente a floresta foi
classificada como categoria excelente, obtendo
todos os semáforos verdes. Conclui-se que a
Cromatografia de Pfeiffer é uma técnica que
pode ser utilizada para avaliação qualitativa
do solo tanto de ecossistemas naturais quanto
agroecossistemas, sendo de simples manuseio
técnico e baixo custo, mostrando-se como uma
alternativa à avaliação de solos por agricultores

Keywords: The development of technology for the study of soil quality such as Pfeiffer’s Chromatography becomes very useful for agroecosystems managed according to agroecological principles, because it is easy to understand, low cost and address aspects related to the movement of life from soil.

The results of the chromatographic evaluations indicate that there were differences in quality among the studied soils of the agroecosystems, being classified in the category sufficient with the traffic lights pointing predominantly yellow color varying between red and green.
