Abstract
Abstract Fertilization can be a sustainable management practice for the maintenance of the threatened species such as Araucaria angustifolia. Our objective was to evaluate the elemental composition of A. angustifolia fertilized with N, P, and K, and how the fertilization altered the soil fertility. Seven-month-old seedlings were transplanted to 16 dm3 soil pots, and three experiments were carried separately (one for each cited element) in a completely randomized design. Overall, the seedlings tended to accumulate nutrients differently among the compartments in the following order: needles > branches > stem. Application of N reduced the soil pH, boosted Mn concentration in more 10 times, decreased the P uptake, and changed the C:N and C:P ratios. Increased doses of P led to higher uptake rates but promoted a reduction in the absorption of Mg. High rates of K diminished of P, Ca, Mg, Mn, and B, confirming antagonism interaction with Ca and Mg.

Scholars like Scheeren et al (1999) and Hess et al (2018) suggest that sustainable management is of utmost importance for future preservation, multiple-use, profitable production and enhancement of the Araucaria Forest in southern Brazil, being one more efficient way to conserve the remains of Araucaria Forest
Summary
Deforestation threatens the earth’s biodiversity and the ecosystem services upon which humans depend (Rhodes et al, 2017). Among the Atlantic Forest Biome phytophysiognomies, the Mixed Ombrophilous Forest (FOM) (the so-called Araucaria Forest) is one of the most threatened (Higuchi et al, 2012; Canei et al, 2018). In this environment, the native Araucaria angustifolia trees have been intensely exploited, stands to the point of accentuated reduction of its natural reserves in the late 1980s and is currently classified as vulnerable to extinction (Canei et al, 2018). For the management, socioenvironmental and socioeconomic maintenance, it is required the search for information that supports the elaboration of management plans based on models generated using multiple factors related to the species and the environment (Orellana & Vanclay, 2018a, 2018b; Ricken et al, 2018)
