Texte intégralResumo: O desenvolvimento radicular em plantações de eucalipto tem sido apontado como uma das estratégias cruciais para sua adaptação e crescimento, em especial, em condições tropicais, que possuem solos pobres em nutrientes. Neste contexto, torna-se extremamente importante avaliar o perfil do solo nestas plantações, a luz de uma perspectiva de fornecimento de nutrientes e água para as plantações de eucalipto. Tendo isto em vista, especificamente nesta tese, dois trabalhos foram conduzidos para avaliar os atributos do solo e o desenvolvimento radicular em plantações de eucalipto no brasil, a saber: 1) Disponibilidade de Água no Solo em Plantios de Eucalipto em uma Cronossequência, e suas Relações com a Produtividade e Densidade Básica da Madeira e suas Estimativas Através de Redes Neurais Artificiais no Brasil; 2) Padrões e Distribuição Vertical dos Atributos do Solo na Plantação de Eucalipto no Brasil. A rede experimental completa possui 34 experimentos plantados em um gradiente climático no Brasil e 2 locais no Uruguai, com 36 locais experimentais no total. Avaliaram-se sítios desde baixo incremento médio anual (13,7 m³ ha-1 ano-1, 61% abaixo da média nacional de produtividade), até sítios com elevada produtividade com IMA de 67,2 m³ há-1 ano-1 (92% acima da média nacional de produção de madeira). No trabalho 1, avaliaram-se14 experimentos, e no trabalho 2, 4 experimentos, todos eles ao longo de um forte gradiente climático no Brasil. No caso do trabalho 1 foram avaliados atributos...

Abstract: The root development in eucalyptus plantations has been pointed out as one of the crucial strategies for their adaptation and growth, especially in tropical conditions, which have nutrient poor soils. In this context, it is extremely important to evaluate the soil profile in these plantations, considering a nutrient and water supply perspective for eucalyptus plantations. With this in mind, specifically in this thesis, two studies were conducted to evaluate soil attributes and root development in eucalyptus plantations in Brazil, namely: 1) Availability of Soil Water in Eucalyptus Plantations in a Chronosequence, and their Relationships with the Productivity and Basic Density of Madeira and its Estimates through Artificial Neural Networks in Brazil; 2) Patterns and Vertical Distribution of Soil Attributes in Eucalyptus Plantation in Brazil. The complete experimental network has 34 experiments planted in a climatic gradient in Brazil and 2 sites in Uruguay, with 36 experimental sites in total. Sites were evaluated from low average annual increment (13.7 m³ ha-1 year-1, 61% below the national average of productivity), to sites with high productivity with an IMA of 67.2 m³ ha-1 year -1 (92% above the national average of wood production). In work 1, 14 experiments were evaluated, and in the work 2, 4 experiments, all of them along a strong climatic gradient in Brazil. In the case of work 1, physical attributes of the soils (clay, silt, total sand, field capacity, permanent wiltin... (Complete abstract click electronic access below)

Texte intégralIncreasing anthropogenic emissions of CO2 to the atmosphere are accelerating climate change. These emissions could be partially compensated by carbon fixation in the oceans, vegetation and soils. In particular, soils contain three times more carbon than the atmosphere, and therefore play a crucial role in climate regulation. It has been suggested that storing carbon in the deep layers of the soil, via rhizodeposition of plants, may be a useful avenue to pursue in order to mitigate climate change. We therefore conducted an experiment at CEREEP-Ecotron Ile-de-France to quantify the input and persistence of rhizodeposited carbon by plants using a continuous 13C-CO2 label. Two wheat varieties with contrasting root systems were planted in mesocosms and grown for a full growing season in a 13C-enriched atmosphere. Our objectives were to quantify the rooting-dependent flux of carbon from the atmosphere to the soil by isotopic tracing with 13C, and to measure its short-term persistence. The results showed that the old variety Plantahof rhizodeposited a larger amount of carbon than the more recent variety Nara, especially at depth. However, the carbon supplied to the soil by these two varieties led to similar amounts of organic C mineralization and priming effects. Thus, the total carbon balance was more related to the effect of soil depth than to the varieties used in the study. Furthermore, I carried out a meta-analysis of the distribution of enzymatic activities as a function of soil depth for hydrolases and oxidoreductases involved in the carbon, nitrogen and phosphorus cycle. The results of this analysis showed that the activity profiles depended very strongly on the way these activities were expressed, with activities mostly decreasing when expressed per soil mass, but remaining rather stable or even increasing with depth when expressed per unit microbial biomass. Taken together, these results show that considering the functioning of the entire soil column is essential to understand the dynamics of carbon in terrestrial ecosystems
