Abstract: The evaluation of the nutritional status in eucalypt (Eucalyptus grandis W. Hill ex Maid.) forests through vegetal tissue analyses what reflects water and nutrient flows in the system, and represents a complementary tool to soil analysis can be helpful to raise and maintain the forest productivity at high levels. This study compared the use of the Diagnosis and Recommendation Integrated System (DRIS), Modified-DRIS (M-DRIS), and Compositional Nutrient Diagnosis (CND) diagnose methods in eucalypt stands in Cent… Show more

“…In Brazil, some studies were carried out with CND in soybean (Urano et al 2006;Urano et al, 2007), eucalyptus (Silva et al, 2004), guava and mango (Parent et al, 2013b). The original CND method used D log-centered ratios (clr) or contrasts as recommended to avoid biases in compositional data analysis (Aitchison, 1986).…”

“…Because nutrient ratios do not inform whether nutrient concentrations are simultaneously too high, too low or adequate [19], they are often used in combination with nutrient concentration ranges. However, combining the critical range approach and DRIS may lead to conflicting results [20][21][22], indicating that those approaches are noisy. Although there are D × (D-1)/2 possible dual ratios for a D-parts composition, the compositional matrix has rank D-1 [23].…”

“…The norms for the nutritional diagnosis of garlic crops were given by the Diagnosis and Recommendation Integrated System (Beaufils, 1973) and the Compositional Nutrient Diagnosis methods (Parent and Dafir, 1992), both using the nutritional status (NS) (Silva et al, 2004) and the sufficiency range (SR) criteria.…”
