“…Araucaria angustifolia is currently defined as a critically endangered native tree species from southern Brazil through intense timber exploitation during the 20th century [10]. In addition to the historic interest in the productive potential of A. angustifolia and the quality of its wood [11], soil fertility characterization, which is one of the main factors contributing to A. angustifolia growth and yield, is still little known. Moreover, due to the lack of knowledge about the ecology of A. angustifolia, mistakes have been made in selecting sites for establishing plantations of this endangered tree species [3] and in the lack of soil management practices inside these sites to condition the soil ecosystem [12].…”

Different site quality levels in Araucaria angustifolia (Bert.) O. Kuntze plantations may influence the soil organisms and the interaction between litter and soil chemical properties by providing habitats and nutrients in different pathways. Our aim here was to understand the effect of site quality level in the interaction among litter, soil–solid phase, and organism assemblage on A. angustifolia, Campo Belo de Sul, Santa Catarina, Southern Brazil. In the low site quality, the litter deposition, litter K content, litter Ca content, soil organic matter, soil P content, soil K content, and soil exchangeable Ca reduced by 50.50, 49.54, 11.89, 20.51, 11.74, 61.18, and 35.18%, respectively, when compared to the high site quality. Nonmetric multidimensional scaling (NMDS) grouped the influence of site quality degree into three groups, considering the dissimilarities among soil organisms. The ordination of the soil organisms, richness, and Shannon’s diversity in each studied site quality degree had a stress value of 0.08. The structural equation models showed that the loss of site quality had a negative relationship with soil organism assemblage and soil and litter compartments. Our study highlights the fact that a fertile soil, a soil enriched in organisms, and enough litter support the forest productivity.

Soil quality is a driver for biodiversity enrichment, soil fertility, and soil organic matter dynamics. Different soil quality levels at Araucaria angustifolia plantations may influence the soil organisms, and the interaction between litter and soil compartments by providing habitat and nutrients in different pathways. Our aim was to present a deeper view of the litter-soil compartments, and soil organisms community composition associated with three degrees of site quality (low-, average-, and high-quality sites), which reflect productivity levels, at the highlands of southern Brazil. The non-metric multidimensional scaling (NMDS) grouped the influence of soil quality degrees in three groups considering the dissimilarities on the soil organisms among each other. The ordination of the soil organisms, richness, and Shannon’s diversity in each studied soil quality degree had a stress value of 0.08. The structural equation models indicated that the loss of soil quality showed a negative relationship among soil organisms’ assemblage, and soil-litter compartments. Our results highlighted the importance of considering soil biotic and abiotic attributes for achieving high productivity levels from A. angustifolia plantations within its natural occurrence range.
