“…Foliage phosphorus concentration changes are simulated explicitly, with the phosphorus content of nonfoliage tissue varying in proportion to that of the foliage, as observed along gradients of soil fertility (Heineman et al, 2016). The phosphorus required (G P ) to sustain the current growth (G C ) of new tissue can therefore be written as…”

“…First, biochemical mineralization is scaled according to the P : N status of vegetation (f PN plant ) to account for the observed link between rizosphere phosphatase activity and plant nutritional status (Fox, 1992;Hofmann et al, 2016). Second, it is scaled with the same equation used to scale mineralization and root uptake according to soil temperature.…”

Abstract. Land surface models rarely incorporate the terrestrial phosphorus cycle and its interactions with the carbon cycle, despite the extensive scientific debate about the importance of nitrogen and phosphorus supply for future land carbon uptake. We describe a representation of the terrestrial phosphorus cycle for the ORCHIDEE land surface model, and evaluate it with data from nutrient manipulation experiments along a soil formation chronosequence in Hawaii.ORCHIDEE accounts for the influence of the nutritional state of vegetation on tissue nutrient concentrations, photosynthesis, plant growth, biomass allocation, biochemical (phosphatase-mediated) mineralization, and biological nitrogen fixation. Changes in the nutrient content (quality) of litter affect the carbon use efficiency of decomposition and in return the nutrient availability to vegetation. The model explicitly accounts for root zone depletion of phosphorus as a function of root phosphorus uptake and phosphorus transport from the soil to the root surface.The model captures the observed differences in the foliage stoichiometry of vegetation between an early (300-year) and a late (4.1 Myr) stage of soil development. The contrasting sensitivities of net primary productivity to the addition of either nitrogen, phosphorus, or both among sites are in general reproduced by the model. As observed, the model simulates a preferential stimulation of leaf level productivity when nitrogen stress is alleviated, while leaf level productivity and leaf area index are stimulated equally when phosphorus stress is alleviated. The nutrient use efficiencies in the model are lower than observed primarily due to biases in the nutrient content and turnover of woody biomass.We conclude that ORCHIDEE is able to reproduce the shift from nitrogen to phosphorus limited net primary productivity along the soil development chronosequence, as well as the contrasting responses of net primary productivity to nutrient addition.

“…Shifts in plant community structure have been observed along soil acidity and fertility gradients of Panamanian tropical forests (John et al 2007;Condit et al 2013;Heineman et al 2016). Some plants can survive on acidic soils by mitigating Al toxicity by complexation of Al 3+ with organic acids released from roots (Fujii 2014;Heineman et al 2016). The shifts in plant community structure toward efficient P utilizers can maintain high biomass production even in P-limited environments (Kitayama et al 2000(Kitayama et al , 2004.…”

Tropical forests are characterized by high biodiversity and aboveground biomass growing on strongly weathered soils. However, the distribution of plant species and soils are highly variable even within a tropical region. This paper reviews existing and novel knowledge on soil genesis, plant and microbial physiology, and biogeochemistry. Typically, forests in Southeast Asia are dominated by dipterocarps growing on acidic Ultisols from relatively young parent material. In the Neotropics and Africa, forests contain abundant legume trees growing on Oxisols developed in the older parent materials on stable continental shields. In Southeast Asia, the removal of base cations from the surface soil due to leaching and uptake by dipterocarp trees result in intensive acidification and accumulation of exchangeable Al 3+ , which is toxic to most plants. Nutrient mining by ectomycorrhizal fungi and efficient allocation within tree organs can supply phosphorus (P) for reproduction (e.g., mast fruiting) even on P-limited soils. In the Neotropics and Africa, nitrogen (N) fixation by legume trees can ameliorate N or P limitation but excess N can promote acidification through nitrification. Biological weathering [e.g., plant silicon (Si) cycling] and leaching can lead to loss of Si from soil. The resulting accumulation of Al and Fe oxides in Oxisols that can reduce P solubility through sorption and lead to limitation of P relative to N. Thus, geographical variation in geology and plant species drives patterns of soil weathering and niche differentiation at the global scale in tropical forests.

“…A diversidade de espécies e estrutura complexa das florestas tropicais e subtropicais remetem à ideia de que essas ocupam solos bastante férteis (HEINEMAN et al, 2016). No entanto, atualmente é reconhecido que os solos desses ecossistemas são de baixa fertilidade (JOHN et al, 2007), o que pode ser atribuído às altas taxas de precipitação e temperaturas, catalisadores do intemperismo, a que estão sujeitas tais regiões.…”

ResumoO objetivo deste trabalho foi avaliar os atributos químicos e físicos de um solo florestal ao longo de uma topossequência, bem como a influência do solo sobre características estruturais e de diversidade da floresta. O estudo foi conduzido em um remanescente de Floresta Ombrófila Mista Aluvial no município de Guarapuava, PR, onde foram instaladas três transecções (A, B e C) no sentido rio-bordadura, divididas em subunidades de 10 x 10 m. Em cada uma das 42 subunidades foram coletadas amostras para a caracterização química e granulométrica do solo (0,0-0,2 m) e efetuada a análise da Resistência à Penetração (RP). Realizou-se análise de agrupamentos (método de ligação completa) para identificar a similaridade das subunidades em relação aos atributos do solo e da vegetação. Uma análise de componentes principais foi efetuada para avaliar as intercorrelações entre as variáveis edáficas e de vegetação e identificar as variáveis de maior expressão na área de estudo. Os resultados indicaram solos com baixa saturação por bases, acidez elevada e alta concentração de Al especialmente nas unidades mais afastadas do rio. Identificou-se um gradiente edáfico nas transecções B e C, com reflexos sobre a estrutura e diversidade da vegetação. Das variáveis edáficas consideradas, o pH foi a mais determinante, exercendo influências sobre os demais atributos do solo e sobre a vegetação. Palavras-chave: Floresta aluvial; química do solo; análise de agrupamentos; análise de componentes principais. Abstract Properties of a forest soil along a topossequence and its relationships with the arboreal community.The purpose of this study was to evaluate the chemical and physical properties of a forest soil along a topossequence, as well as the influence of the soil on structural and diversity characteristics of vegetation. The study was conducted in a remnant of Alluvial Araucaria Forest in Guarapuava, PR, where three transects (A, B and C) were installed towards the river-boundary direction, divided into subunits of 10 x 10 m. In each subunit samples were collected for chemical and particle size characterization of soil (0.0-0.2 m) and performed the analysis of Penetration Resistance (PR). We conducted cluster analysis to identify the similarity of the subunits in relation to soil properties and vegetation. A principal component analysis was performed to evaluate the interrelations between soil variables and vegetation and to identify the variables with the highest expression. The results indicated soils with low base saturation, high acidity and high concentration of Al. A soil gradient were identified in transects B and C, with reflections on the structure and diversity of vegetation. Of soil variables considered, the pH was the most decisive, exerting influence on other soil and on vegetation characteristics.
