Abstract
Este tem objetivo a elaboração de cartas de suscetibilidade à erosão e à dispersão dos solos do Estado do Ceará, baseado em informações pedológicas disponibilizadas pela EMBRAPA (Empresa Brasileira de Pesquisa Agropecuária) – Serviço Nacional de Levantamento e Conservação de Solos (SNLCS). As cartas de suscetibilidade correlacionam características gêneses dos solos com suas propriedades geotécnicas, de modo a produzir informações a respeito da suscetibilidade a erosão e a dispersão. No que tange à ocorrência dos tipos de solos, o Estado do Ceará possui três tipos preponderantes, sendo o de maior ocorrência os solos do tipo Argissolos ABSTRACT: This work aims to develop letters of susceptibility to erosion and soil dispersion in the State of Ceará, based on pedological information provided by EMBRAPA (Brazilian Agricultural Research Corporation) - National Service for Survey and Soil Conservation (SNLCS).
