Última Methods to Quantify Nickel in Soils and Plant Tissues Rev. Bras. Ciênc. Solo Rodak,Bruna Wurr; Moraes,Milton Ferreira de; Pascoalino,João Augusto Lopes; Oliveira Junior,Adilson de; Castro,Cesar de; Pauletti,Volnei. In comparison with other micronutrients, the levels of nickel (Ni) available in soils and plant tissues are very low, making quantification very difficult. The objective of this paper is to present optimized determination methods of Ni availability in soils by extractants and total content in plant tissues for routine commercial laboratory analyses. Samples of natural and agricultural soils were processed and analyzed by Mehlich-1 extraction and by DTPA. To quantify Ni in the plant tissues, samples were digested with nitric acid in a closed system in a microwave oven. The measurement was performed by inductively coupled plasma/optical emission spectrometry (ICP-OES). There was a positive and significant correlation between the levels of available Ni in the...
