The performance of via dry (DVS) and acid microwave assisted digestion methods (DAAM) was evaluated in the analysis of sugar cane leaf samples. The usual laboratory detection techniques were evaluated [P: visible molecular absorption spectrometry (UV-VIS); K: emission atomic spectrometry (AES); Ca, Mg, Cu, Zn: Flame atomic absorption spectrometry] respect to the Total reflection X ray fluorescence technique (TXRF), for the results obtained by two digestion methods. Digestion methods accuracy and precision was determined through the use of two certified samples: plant tissue n°6 and n°11 (Accreditation and Normalization Commission - Chilean Society of Soil Science) P determination via TXRF reported better results with respect to UV-VIS in su...
