Litterfall and Accumulated Nutrients in Pinus taeda Plantation and Native Forest in Southern Brazil

The dynamics of the production, chemical composition, and accumulated nutrients in litterfall are essential to understand the availability of nutrients and, consequently, possible gains in productivity in different forest types. Thus, the objective of the present study was to evaluate the litterfall and the accumulated nutrients in litterfall in a Pinus taeda plantation and native forest from southern Brazil. Two forest types: (i) an eight-year-old Pinus taeda L. plantation; and (ii) a native forest fragment, located in southern Brazil, were studied for four years. The monthly and annual litterfall production, chemical composition, accumulated nutrients, and nutrient use efficiency of the litterfall were evaluated. The Pinus taeda plantation showed higher values of leaves/needles litterfall and N, P, K, Ca and Mg use efficiency. This demonstrates that Pinus taeda plantations have a high production of needle biomass, which, in turn, has increased cell division, favoring the entry of these nutrients into the soil via decomposition. Our results show that total litterfall production did not significantly influence the accumulated nutrient and nutrient efficiency of litterfall, demonstrating that evaluating litterfall fractionation, such as leaves/needles, twigs and miscellaneous, is essential to understand the quantity and quality of litterfall and, thus, the nutrient cycling, which can contribute to possible silvicultural practices to be implemented, which can provide growth gains in forest types.

The Araucaria forests of Southern Brazil have been drastically reduced as a result of anthropic intervention and are currently found at different stages of succession. The objective of our study was to understand the influence of forest fragmentation on the phytosociological composition of its tree component. The composition of floristic groups of the tree component and their correlation with the edaphic and environmental variables in a fragment of the Araucaria Forest in the municipality of Curitibanos, state of Santa Catarina, Brazil was analyzed. A hundred and ten permanent continuous plots (10 m²) with forest edges of different origins and formation times were established for sampling. Trees with diameter ≥ 5 cm at breast height (DBH) were measured and identified. Using TWINSPAN, data were analyzed for species importance values (including indicator species) in the formation of floristic groups. Floristic similarities resulted in separating groups conditioned by the forest succession. The presence of the invasive species Pinus taeda L. and pioneer species at the forest expansion border contributed to the formation of a spatially cohesive group. The other areas did not show influence of edge effects, being in an initial secondary succession stage, dominated by Jacaranda puberula Cham. Low edaphic variation among the classes of lithosols in a flat relief had no influence on the formation of floristic groups.

Pinus Taeda L

Background: Taper modelling and volume estimation are key procedures in the management and planning of plantedforests. The objective of this work was to evaluate the taper and volume behaviour of Pinus taeda L. species, along the stemin different ages, using the Preussner taper functions, compared to Schöpfer’s 5th-polynomial, Kozak’s and Max-Burkhart’smodels. This work focused on plantations of Pinus taeda L., due to its wide use as a source of raw material in the forestindustry of southern Brazil. Methods: The data were collected in the last 22 years from the Midwest region of Santa Catarina, of trees ranging in agefrom 3.5 to 18 years. This dataset consisted of a collection of volume sections, with relative diameter measurements alongthe stem, used in conventional forest inventory. The total volume of the trees, obtained by integrating the Preussner taperfunctions, was equated by dividing the stem into four parts, in which parabolas were fitted, and compared with the totaland merchantable volume estimated by Schöpfer’s 5th-degree polynomial, Kozak’s and Max-Burkhart’s functions. Results: Bias, RMSE and r were generally better with the application of Kozak’s model, and AIC and BIC for the Preussner’smodel. Conclusions: Kozak functions were better to provide the merchantable volume. In terms of total volume both functions,Kozak and Preussner, provided reliable estimates. The advantage of the procedure proposed by Preussner is the flexibilityof the fitted taper functions, the simplicity of volume calculations by integration, and the feasibility for interpreting theircoefficients.

Cool Dry Season

This study evaluated the soil basal respiration (SBR) of three forest types and seasons and their correlation with pedological attributes in the 0-5 cm land layer. Therefore, we selected two areas of commercial tree species in the central-southern Paraná region: one plot of Pinus taeda and one of Eucalyptus dunnii; and a control, a patch of native forest (Mixed Ombrophyllous Forest). We determined the SBR by the alkaline addition method, incubating the samples for seven days. We collected samples in the cool dry season (winter) and in the hot humid season (summer). Soil attributes were determined by a routine analysis (pH, K+, Ca2+, Mg2+, Al3+, P, Matéria Orgânica, areia grossa e areia fina, silte, argila e V%). We observed significant SBR differences only about summer and winter. SBR correlated significantly with organic matter. These results are similar to most of the literature. There was no difference between the forest types about the SBR, showing that even monoculture forests can present carbon fluxes statistically equal to those of an intermediate successional stage native forest. The specific edaphic fauna adapted to each ecosystem may explain the absence of this difference in relation to SBR.
