Radiação gama e resistividade elétrica em solo com aplicação de carbonatito e fertilizantes agrícolas no Distrito Federal

Abstract: ABSTRACT. EMBRAPA (Empresa Brasileira de Pesquisa Agropecuária) and Brasília University developed a research project about the viability of carbonatite rock as agricultural fertilizer. As an initial experiment, several mixtures of carbonatite, limestone, phosphorous and potassium compounds were added as fertilizers in an oxisol area (red-latosol, according with Brazilian System of Soil Classification), in Distrito Federal, central Brazil. The experiment area was divided in 56 plots (4 × 7 m) and each plot rece… Show more

“…Na pesquisa realizada por Nascimento et al (2008), observou-se que a adição de fertilizantes ao solo modifi cou suas características de resistividade elétrica. Os resultados revelaram que a resistividade elétrica do solo mostrou-se capaz de diferenciar as regiões com adição de fertilizantes no solo.…”
