1. Carbon stock and organic fractions in soil under monoculture and Sorghum bicolor–Urochloa ruziziensis intercropping systems
ABSTRACT The use of no-till conservationist agricultural systems as well as intercropping in the Cerrado biome are practices that increase soil organic matter (SOM) due to the deposition of straw. This study aimed to quantify the carbon stock and organic fractions of a latosol under off-season monoculture (Sorghum bicolor and Urochloa ruziziensis) and interc

3. Soil carbon accumulation in cotton production systems in the Brazilian Cerrado
ABSTRACT. Sustainable production systems, such as the no-tillage system (NTS), have a tendency to increase organic carbon in the soil. However, in Brazilian cotton production, the conventional tillage system (CTS) is predominant, and long-term studies on cotton crop under the NTS are scarce. The present study aimed to evaluate the effect of soil management a

4. Changes in organic carbon in soil of natural grassland converted to Pinus taeda plantations at three ages
Resumo O plantio de pinus em áreas de campo natural (NG) pode alterar as formas e estoques de carbono orgânico (OC) do solo. Visando quantificar essas alterações, foram determinados os teores e estoques de OC total (TOC) e das frações particulada (POC) e associadas aos minerais (MAC) em cinco camadas, entre 0,0 e 0,4 m de profundidade, do solo sob usos

5. Carbon fractions and stock in response to solid and fluid organomineral fertilizers in highly fertile soils
Resumo: O objetivo deste trabalho foi avaliar o efeito da aplicação de fertilizantes organominerais e minerais em solos com fertilidade construída sobre o índice de manejo de carbono (IMC) e as frações e o estoque de carbono. O experimento foi realizado em um Cambissolo e em um Nitossolo sob sistema plantio direto, por três anos agrícolas. Os tratame

6. Soil carbon stock and humification in pastures under different levels of intensification in Brazil
ABSTRACT: Intensive management of tropical pastures has shown potential for greenhouse gas (GHG) mitigation due to high forage production and C accumulation in the soil. This study aimed to evaluate different pasture management options in relation to their effect on soil C stocks and soil organic matter (SOM) humification. Pastures in four beef cattle produc

7. Carbon Stocks and Pools in Relation to the Texture of Kaolinitic Soils from the Brazilian East Coast
ABSTRACT: Extremely kaolinitic soils of Tertiary age elevations on the Brazilian east coast present a wide range of texture, which is recognized as one of the main factors controlling the soil organic matter contents. This study aimed to investigate the organic C storage of different compartments of kaolinitic soils. The studied soils had a wide particle siz

8. Long-Term Effect of Soil Use and Management on Organic Carbon and Aggregate Stability
ABSTRACT: The conversion of native grassland into farmland causes changes in the soil. Tillage has profound effects on soil organic matter. The intensification of soil tillage decreases soil quality by reducing aggregate stability. Soil aggregate stability and soil organic matter are key indicators for soil quality and environmental sustainability in agro-ec

9. Soil aggregation and carbon stabilization in burn and no-burn sugarcane management systems
ABSTRACT Retaining sugarcane straw over the soil after harvesting can improve soil structure and increase soil carbon stabilization, mainly in macroaggregates. We evaluated the carbon content in the aggregate classes in areas under burn and no-burn (adopted for five years) sugarcane management systems, focusing on the superficial layer (0.00-0.20 m). The exp

10. Hydropedology of a High Tableland with Cerrado, Brazilian Central Plateau: the Frutal Catchment Case Study
ABSTRACT: Currently, the Brazilian savanna (Cerrado) represents the main agricultural area of the country, comprising a great variety of landscapes and soils, geological formations and vegetation patterns, as well as the major watershed. We studied the hydropedology and morphometry of a representative catchment (Frutal river), on a high tableland (Chapada) i

11. The use of Pedotransfer functions and the estimation of carbon stock in the Central Amazon region
ABSTRACT Computer models have been used to assess soil organic carbon (SOC) stock change. Commonly, models require to determine soil bulk density (Db), a variable that is often lacking in soil data bases. To partly overcome this problem, pedotransfer functions (PTFs) are developed to estimate Db from other easily available soil properties. However, only a fe

12. Carbon losses and soil property changes in ferralic Nitisols from Cuba under different coverages
ABSTRACT The transformation of primary forestlands into lands under cultivation exerts an impact on the physical and chemical properties of the soils, leading to loss of carbon from the soil. The aims of this study were (1) to estimate the impact of different land use on organic carbon stock (OC-stock) and (2) to determine the clay percentage, the dispersion
