Resumo: The deficiencies or micronutrients excesses in the soil can be diagnosed by several procedures. Among these, the chemical analysis of the soil is a prominence instrument, because it makes possible the previous evaluation of micronutrients available to the plants. In spite of many laboratories accomplish micronutrients chemical analyses in the soil, the lack of methodologies standardisation can commit the reliability of the results. Analytical procedures standardisation is an unquestionable need, when it intend to guarantee quality and credibility to the results. This study was carried out with the objective of comparing analytical procedures, seeking to contribute with new knowledge for definition and methodological standardisation of micronutrients chemical analyses of soil samples. The procedures of decantation for 16 hours and the filtration with filter paper Whatman 42, showed differents contents for iron, cooper, zinc and manganese in soil samples, don’t having possibility for alternative use. The choice of one this procedures it should result in a standardisation to all the participant laboratories of quality control.

Dentre estes se destaca a análise química, uma vez que possibilita a avaliação prévia da disponibilidade destes nutrientes para as plantas. Apesar de muitos laboratórios realizarem análises para micronutrientes em amostras de solo, a falta de padronização de procedimentos metodológicos pode comprometer a comparação de resultados. Uniformizar procedimentos analíticos é uma necessidade indiscutível, quando se pretende garantir qualidade e credibilidade aos resultados. Este estudo foi realizado com o objetivo de comparar procedimentos analíticos, visando contribuir com novos conhecimentos para definição e padronização metodológica para análises químicas de micronutrientes em amostras de solo. A decantação por dezesseis horas e a filtração com papel Whatman nº 42, resultaram na determinação de teores diferentes para os micronutrientes ferro, cobre, zinco e manganês em amostras de solo, não possibilitando uso alternativo. A escolha de um destes procedimentos deve resultar em uma padronização para todos os laboratórios participantes da rede de controle de qualidade.UEL2005-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/227610.5433/1679-0359.2005v26n1p49Semina: Ciências Agrárias; Vol. 26 No. 1 (2005); 49-52Semina: Ciências Agrárias; v. 26 n. 1 (2005); 49-521679-03591676-546Xreponame:Semina.
