Gamaespectrometria, resistividade elétrica e susceptibilidade magnética de solos agrícolas no noroeste do estado do Paraná

Abstract: ABSTRACT. Gamma-ray spectrometry, electrical resistivity, and magnetic susceptibility measurements were taken from agricultural areas near the City of Maringá, in the Northwest region of the Paraná state, south Brazil, in order to characterize the spatial distribution of radionuclides (K, eU, and eTh), the apparent resistivity, and the magnetic susceptibility determined for soils. Three different types of soils are present in this agricultural area: Alfisoil, clayey texture Oxisoil, both deriving from Lower Cr… Show more

“…These results, comparing the soil loss with spatial variability of MS are scarce in literature. According to BECEGATO et al (2005), geophysical researches in agricultural soils are still very incipient in Brazil. In this sense, the author emphasizes the importance of using MS as a promising tool to investigate the spatial variability of other soil variables in the context of soil-landscape relation, providing better understanding of the pedologygeomorphology relations.…”

“…Outro módulo (23,5 × 23,0 × 9,0 cm) armazena (mais de 8.500 leituras) e processa os dados medidos, os quais podem ser transferidos para um computador através de um cabo RS-232. O GS-512 foi calibrado (veja procedimentos em Becegato & Ferreira, 2005) No caso do perfil Tibagi, por exemplo, ao longo dos 250 m de exposição da Formação Ponta Grossa, com o modelo GS-512, foram feitas medidas espaçadas de 50 cm nos arenitos e 100 cm nos folhelhos, envolvendo aproximadamente 310 leituras, com tempo de integração de 120 segundos, consumindo 620 minutos, portanto menos da metade do tempo requerido pelo GRS-500 para realizar a mesma tarefa.…”

“…Isso, consequentemente, leva a um comportamento diferenciado da condução da corrente elétrica em diferentes tipos de solos (YOON & PARK, 2001;BECEGATO & FERREIRA, 2005;SAMOUËLIAN et al, 2005) -como os arenosos e argilosos -bem como à presença de água, substâncias metálicas, sais e outros solutos presentes nos poros dos solos, o que interfere na resistividade elétrica.…”
