Resumo: 	The objective of the present work was to compare three different methods of chemical analysis of vegetable tissue: the method of nitro-percloric digestion, Tedesco et al. and Adler &amp; Wilcox. As material was analyzed 03 samples of the fraction leaves of the litter collected in each one of the two Seasonal Deciduous Forest fragments, collected in August of 1990 in the forest of the “Hill of the Elephant” (Santa Maria city, RS) and in August of 1995 in Santa Tereza’s forest, RS. The analyses were made at the Laboratory of Forest Ecology, in Department of Forest Sciences of UFSM. The results evidenced that the content of P extracted for the method of Adler &amp; Wilcox and the nitro-percloric digestion was similar. The contents of K extracted for the three methods were similar. The method of nitropercloric digestion extracted high contents of Ca and relatively superiors of Mg. The method Tedesco et al. it presented smaller extraction efficiency for P, Ca and Mg. In spite of the largest extraction efficiency, the method of digestion nitropercloric presents larger use risks.
