Potencial de extratos vegetais de cana-de-açúcar na neutralização da acidez do solo por método laboratorial

Abstract: Extratos vegetais Cana-de-açúcar Colheita mecanizada Toxidez por Al Compostos orgânicos KEYWORDS Plant extracts Sugarcane Mechanized harvest Al toxicity Organic compounds RESUMO: Os ácidos orgânicos provenientes da decomposição de resíduos vegetais são capazes de interagir com elementos da solução do solo, formando complexos orgânicos com alumínio, cálcio e magnésio, atenuando assim, a toxidez por alumínio e aumentando a mobilidade de cátions em seu perfil. O objetivo deste trabalho foi avaliar a eficiência de… Show more

“…The reduction of aluminum content with doses of chicken manure increased probably occurred due to the complexing capacity of organic matter, since Al 3 + is the second metal ion more complexed by functional groups of organic matter [22]. The organic acids interact with the present elements in the soil solution and they form organic complexes with Al, Ca, and Mg, thus raising the potential for acidity neutralization and mobility of exchangeable cations in the soil [23].…”
