1. Carbon and Nitrogen Stocks Under Different Land-Use in the Paraopeba River Basin-MG Before the Corrégo do Feijão Dam Burst
ABSTRACT Soil attributes can provide indicators for the management and conservation of natural and agrarian ecosystems. This study was carried out before the rupture of the Córrego do Feijão dam and aimed to evaluate and quantify the stocks of carbon, nitrogen and the C/N ratio in soils around the Paraopeba-MG river basin in five regions corresponding to t

2. PHYSICAL FRACTIONATION AND CARBON AND NITROGEN STOCKS IN SOIL AFTER POULTRY WASTE APPLICATIONS
RESUMO Resíduos da produção de peru frequentemente são utilizados como fertilizantes em pastagens próximas a regiões produtoras. Esses resíduos podem contribuir para a elevação dos estoques de carbono e nitrogênio no solo. Neste estudo objetivou-se avaliar os efeitos acumulados de nove aplicações de doses de cama de peru nas frações e estoques

3. Fertilidade do solo e estoques de carbono e nitrogênio sob sistemas agroflorestais no Cerrado Mineiro
Resumo Os sistemas agroflorestais são utilizados para diversificar a produção de alimentos, proporcionar aumento na biodiversidade da fauna e da flora e conservação do carbono e nutrientes no solo. Sendo assim, o objetivo deste estudo foi avaliar a fertilidade e os estoques de carbono (C) e nitrogênio (N) do solo após dez anos de implantação de sist

4. ORGANIC MATTER AND SOIL FERTILITY IN DIFFERENT SUCCESSIONAL STAGES OF SEASONAL SEMIDECIDUAL FOREST
RESUMO O acúmulo e as transformações da matéria orgânica do solo são fundamentais para a manutenção e melhoria dos atributos químicos, físicos e biológicos do solo, e, consequentemente, para o funcionamento das florestas tropicais. O objetivo deste estudo foi avaliar a influência de florestas secundárias com diferentes estádios sucessionais na

5. Contribution of Eucalyptus Harvest Residues and Nitrogen Fertilization to Carbon Stabilization in Ultisols of Southern Bahia
ABSTRACT: Eucalyptus forests in southern Bahia (BA) are planted in soils with a sandy surface layer and humid tropical climate, conditions that lead to soil carbon (C) decomposition. Recent studies have shown that nitrogen (N) may be important for soil C stabilization. The aim of this study was to evaluate the contribution of Eucalyptus harvest residues and

6. Organic Matter Stocks and the Interactions of Humic Substances with Metals in Araucaria Moist Forest Soil with Humic and Histic Horizons
ABSTRACT Soils with humic and histic horizons in tropical and subtropical ecosystems play an important role in determining the atmospheric C stock and its stabilization, climate regulation, water holding capacity, and environmental filtering, due to the different functions of soil organic matter (SOM). However, the processes and mechanisms that regulate SOM

7. Soil Organic Matter Quality in Jatropha spp. Plantations in Different Edaphoclimatic Conditions
ABSTRACT The substitution of native vegetation by agricultural ecosystems can change the quantity and quality of soil organic matter (SOM), and the intensity of these changes depends on the soil type, climate, and land use. The objective of this study was to evaluate the quality of organic matter in chronosequences of Jatropha cultivation in contrasting soil

8. Carbon and Nitrogen Stocks and Humic Fractions in Brazilian Organosols
ABSTRACT Despite limited geographic expression of Organosols in Brazil, their high carbon storage capacity and natural environmental vulnerability justifies further studies on C and N stocks in these soils and their relationship to the nature of organic matter. Evaluation of physical and chemical properties of organic soils and their ability to store C is im

9. Changes in Soil Organic Carbon and Nitrogen Stocks in Long-Term Experiments in Southern Brazil Simulated with Century 4.5
ABSTRACT The Century model has successfully simulated soil organic matter dynamics in many agroecosystems. However, initial applications in southern Brazil produced mixed results. The objective of this study was to calibrate and validate Century 4.5 to simulate soil carbon (C) and nitrogen (N) dynamics under diverse soil management practices in subtropical B

10. Carbon sequestration and greenhouse gases emissions in soil under sewage sludge residual effects
The large volume of sewage sludge (SS) generated with high carbon (C) and nutrient content suggests that its agricultural use may represent an important alternative to soil carbon sequestration and provides a potential substitute for synthetic fertilizers. However, emissions of CH4 and N2O could neutralize benefits with increases in soil C or saving fertiliz

11. Chemical composition and stocks of soil organic matter in a south Brazilian oxisol under pasture
Este estudo investigou a composição química e distribuição da matéria orgânica do solo (SOM) em compartimentos de Oxissolo sob pastagem nativa sem queima há 41 anos (NP), pastagem nativa sem queima há oito anos (BP), pastagem nativa em solo com calcário e adubado, sem queima há 41 anos (AP), e mata nativa (NF). Os estoques de carbono (C) e nitrog�

12. Matéria orgânica e atributos químicos em solo de tabuleiros costeiros sob diferentes coberturas vegetais / Organic matter and chemical attributes of an Coastal Tableland soil under different vegetation covers
The conversion of native vegetation in agricultural and forest crops results in changes in soil properties. The aimed was to assess the dynamic attributes of a Yellow Oxisol under differents vegetation covers in the Coastal Tableland. Soil samples were collected at depths of 0-10, 10-20 and 20-40 cm in June 2011 in Sooretama, ES, considering four soil vegeta
