“…The non-linear forest ecosystem model ForSAFE has correctly reproduced the chemical aspects of soil water, aboveground biomass, and N and P concentrations in coniferous forests [74]. The concentrations and distribution of Al, Ca, Cl, K, Mg, and Mn in distinct fractions of the aboveground biomass in pine forests were estimated using a compartment model [75]. Thus, the studied elements in the present study followed the same pathways inside the tree, allowing an understanding of the cycling of nutrients in forest ecosystems that suffered radioactive accidents.…”

The prediction of biological processes, which involve growth and plant development, is possible via the adjustment of mathematical models. In forest areas, these models assist in management practices, silviculture, harvesting, and soil fertility. Diameter, basal area, and height are predictors of volume and biomass estimates in forest stands. This study utilized different non-linear models for estimating biomass and nutrient values in the aerial biomass and roots of an unmanaged eucalypt stand in Cerrado dystrophic soil. It was hypothesized that the models would estimate the nutrients of the aboveground biomass and roots after meeting the selection and validation criteria. By statistical analysis of the parameters and subsequent validation, the Schumacher–Hall model was presented to be the best fit for biomass and nutrients. This result confirmed the ability of different variables, including diameter, basal area, and height, to be predicted. Estimating the nutrient values in the aboveground biomass and roots allowed a better understanding of the quality of the vegetal residues that remained in the soil. For dystrophic soils, which occur in the Cerrado, these estimates become even more relevant.

Leaf nutrient resorption differs among canopy and understory plant species in subtropical Eucalyptus and Acacia plantations

Although plants are known to conserve nutrients by resorbing them from senescing leaves, how resorption of foliar macro‐ and micronutrients is affected by plant growth form (e.g., trees, shrubs, and ferns) and forest age are not well understood. The current study was conducted in four subtropical monoculture plantations: Eucalyptus and Acacia plantations in 14 and 35 years old, respectively. Leaf resorption efficiencies (REs) and resorption proficiencies (RPs) of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and manganese (Mn) of the canopy trees and understory shrubs and ferns were determined. N, P, and K but not Ca and Mn were generally resorbed from senescing leaves. RE was significantly higher for P than N, indicating that P was more limiting than N in the subtropical plantations. Nutrient REs did not differ with plantation age, while nutrient RPs generally tended to be lower in the 14‐year‐old than in the 35‐year‐old plantations. REs significantly differed among canopy and understory plant species with different growth forms, that is, NRE, PRE, and KRE values were much higher in woody plants (especially the canopy tree species) than in ferns. REs were correlated with foliar nutrient concentrations but not with soil nutrient concentrations. Our findings suggest that resorption of nutrients from senescing leaves differs among canopy and understory plants, and implicate that introducing native tree species into these plantations could be implemented for accelerating the community succession and further improving the multifunctionality.

Chlorine (Cl) in the terrestrial environment is of interest from multiple perspectives, including the use of chloride as a tracer for water flow and contaminant transport, organochlorine pollutants, Cl cycling, radioactive waste (radioecology; 36Cl is of large concern) and plant science (Cl as essential element for living plants). During the past decades, there has been a rapid development towards improved understanding of the terrestrial Cl cycle. There is a ubiquitous and extensive natural chlorination of organic matter in terrestrial ecosystems where naturally formed chlorinated organic compounds (Clorg) in soil frequently exceed the abundance of chloride. Chloride dominates import and export from terrestrial ecosystems while soil Clorg and biomass Cl can dominate the standing stock Cl. This has important implications for Cl transport, as chloride will enter the Cl pools resulting in prolonged residence times. Clearly, these pools must be considered separately in future monitoring programs addressing Cl cycling. Moreover, there are indications that (1) large amounts of Cl can accumulate in biomass, in some cases representing the main Cl pool; (2) emissions of volatile organic chlorines could be a significant export pathway of Cl and (3) that there is a production of Clorg in tissues of, e.g. plants and animals and that Cl can accumulate as, e.g. chlorinated fatty acids in organisms. Yet, data focusing on ecosystem perspectives and combined spatiotemporal variability regarding various Cl pools are still scarce, and the processes and ecological roles of the extensive biological Cl cycling are still poorly understood.
