Abstract The Brazilian government aims at augmenting the area cropped under no-tillage (NT) from 32 to 40 million ha by 2020 as a means mitigate CO 2 emissions. We estimated soil carbon (C) sequestration continuous NT systems in two municipalities Goiás state that are representative of Cerrado. A chronosequence fields different age since conversion conventional tillage (CT) was sampled 2003 and 2011. Soil C levels native Cerrado pasture were measured for comparison. After about 11 14 years,...
O objetivo deste trabalho foi analisar os benefícios e as perspectivas potenciais de sistemas integração lavoura-pecuária no processo intensificação uso das áreas em exploração com lavoura grãos pastagens Cerrado, apontar principais lacunas informação sobre o sistema. Os da são: melhoria propriedades químicas, físicas biológicas do solo; redução ocorrência doenças, insetos-pragas plantas daninhas; maior produtividade dos animais; riscos pela diversificação atividades. No entanto, a adoção...
Several methods exist for determining soil organic carbon, and each one has its own advantages limitations. Consequently, a comparison of the experimental results obtained when these are employed is hampered, causing problems in carbon stocks soils. This study aimed at evaluating analytical procedures used determination their relationships with mineralogy texture. Wet combustion methods, including Walkley-Black, Mebius Colorimetric as well dry such Elemental Gravimetric Analysis were used....
Abstract Aim Macroinvertebrates comprise a highly diverse set of taxa with great potential as indicators soil quality. Communities were sampled at 3,694 sites distributed world‐wide. We aimed to analyse the patterns abundance, composition and network characteristics their relationships latitude, mean annual temperature rainfall, land cover, texture agricultural practices. Location Sites are in 41 countries, ranging from 55° S 57° N 0 4,000 m elevation, rainfall 500 >3,000 mm temperatures...
O objetivo deste trabalho foi avaliar o impacto de sistemas integração lavoura-pecuária sobre atributos físico-hídricos do solo e potencial uso desses como indicadores da qualidade física um Latossolo. As amostras foram coletadas nas camadas 0-5, 10-15, 20-25 40-45 cm. Todos os manejo alteraram significativamente a densidade, umidade volumétrica, resistência à penetração, porosidade total, macroporosidade, microporosidade efetiva água prontamente disponível solo. Foram observados incrementos...
O uso racional do solo tem sido objeto de estudo e discussões em função da busca alternativas tecnológicas que possibilitem o manejo correto e, consequentemente, uma agricultura sustentável. Objetivou-se, com este trabalho, levantar dados sobre a qualidade físico-hídrica sua relação os impactos gerados pelo por meio revisão bibliográfica, contribuindo para melhor conhecimento das informações disponíveis na literatura. indicadores física permite designar práticas adequadas solo. Uma análise...
Near‐infrared reflectance spectroscopy (NIRS) has been accepted as a fast method to evaluate various soil constituents. However, very few studies have used NIRS predictor of the textural and mineralogical content tropical soils. The objective this study was investigate potential use tool for assessment diverse properties, with specific attention prediction properties related mineralogy wide range Latosols from Cerrado region central Brazil. samples, 148 in total, taken 0.0 0.2 0.6 0.8‐m...
The objective of this work was to assess the effects integrated crop-livestock systems, associated with two tillage and fertilization regimes, on abundance diversity soil macrofauna. Four different management systems were studied: continuous pasture (mixed grass); crop; rotations (crop/pasture pasture/crop); native Cerrado as a control. Macrofauna sampled using modified Tropical Soil Biology Fertility method, all individuals counted identified at morphospecies level for each plot. A total...
O objetivo deste trabalho foi caracterizar a macrofauna edáfica e avaliar o efeito de plantas cobertura em plantio direto, nos principais grupos da do solo, duas épocas avaliação um Latossolo Vermelho distroférrico. delineamento experimental blocos ao acaso, com oito tratamentos (plantas cobertura) quatro repetições. As cobertura: Crotalaria juncea, guandu-anão (Cajanus cajan), Stylosanthes guianensis, Brachiaria brizantha, B. brizantha consorciada milho (Zea mays), milheto (Pennisetum...
Abstract The objective of this work was to evaluate the dynamics soil microbiological attributes under integrated production systems, continuous pasture, and native cerrado. study conducted in a transition area from crop livestock. Four areas with different land uses were evaluated: an crop-livestock-forestry system (ICLFS), cultivated Eucalyptus urograndis alley cropping, spaced 2x2 m between plants 22 alleys; crop-livestock (ICLS); besides two adjacent cerrado used as reference. For...
Abstract The nitrous oxide (N 2 O) emissions in agricultural systems are influenced by edaphoclimatic conditions, and the availability of soil organic matter (SOM) is a key factor. objective this study was to evaluate accumulation labile stable SOM fractions possible relations with N O using multivariate approach 24‐year integrated crop–livestock experiment Cerrado region. management consisted of: continuous cropping under no tillage (CC‐NT), annual heavy disc harrow (CC‐CT), an system...

The change in land use the Brazilian Cerrado modifies dynamics of soil organic matter (SOM) and, consequently, carbon (C) stocks and their fractions enzyme activities. This study evaluated effect brachiaria (Brachiaria decumbens Stapf.) intercropped with Arabica coffee (Coffea arabica L.) on stock experiment was arranged a completely randomized block design three replications treatments factorial design. first factor consisted or without brachiaria, second cultivars (‘I.P.R.103’ ‘I.P.R.99’)...
Bioinputs are natural products applied to crops that contribute more sustainable agriculture by boosting yields and reducing environmental impacts. In Brazil, the use of bioinputs such as Bradyrhizobium in soybean has been consolidated, but expansion on-farm bioinput production is currently initiating a new revolution. Furthermore, applications cash Brazil have shed light on great potential growth-promoting microorganisms (GMPs) improve nutrient uptake increase productivity. This study...
Coffee intercropped with Urochloa decumbens modifies nutrient uptake, and consequently the yield quality of coffee, by greater release nutrients efficient cycling. There is little information about increasing content in Arabica coffee plants decumbens. The objective this study was to evaluate effect two cultivars (Coffea arabica L.) on levels macro- micronutrients crop yield. experiment conducted at Embrapa Cerrados, Planaltina-DF, arranged a completely randomized block design three...
