The paper had as its objective to estimate the precaution limits and control for macro and micro nutrients, present in different components of the biomass, of Acacia mearnsii, Eucalyptus spp. and Pinus taeda. The 40,183 analyses were separated by chemical element, component and species. The limits with base in the results of the tests of adherence to the normal distribution and in the classification criteria were established. The results of the obtained medium tenors are inside of the strip of values found in the literature for the studied forest species, components of the biomass and chemical elements. The levels of the chemical elements are different among the species for each type of analyzed component. Independent of the studied forest species, the leaves and needles presented larger values while the buds trunk smaller. The limits, proposed in the work, allow greater control in the classification of the results, increasing the reliability in the nutritional analyses.
