O uso intensivo do solo para a produção de hortaliças resulta em elevada degradação do solo e da área de cultivo. A utilização de técnicas e recursos que viabilizem a produção sob condições desfavoráveis pode ser decisiva para agricultura. Desta maneira, o objetivo deste trabalho foi avaliar os efeitos isolados e conjuntos da correção do solo e da aplicação de tiamina sobre o desenvolvimento das plantas de pimentão. Os tratamentos foram compostos por três diferentes saturações de base do solo (36, 60 e 80%), combinadas à aplicação de tiamina via foliar (com e sem) na concentração de 100 mg L-1. Verificou-se que a tiamina ameniza os efeitos da baixa saturação por base do solo sobre as características fisiológicas das plantas de pimentão. Os incrementos...

Social networks and environmental management at multiple levels: soil conservation in Sumatra
Provedor de dados: 7
Autores: Matous, Petr; University of Tokyo; University of Sydney; petr.matous@sydney.edu.au.
Many agrarian communities in developing countries suffer from insufficient productivity and use farming practices that deteriorate the environment both locally and globally. Research suggests that social networks play a role in environmental management, different studies emphasize different aspects of network structures, and the implications of the scales at which networks operate are not explicitly discussed. Here, I ask what types of social structures in farmer networks are conducive to environmental protection and agricultural productivity enhancement, and I show that the answer depends on the scale of the investigation. Using original data representing 16 farmer groups comprising 315 households and 1575 information-sharing links, I analyzed the...

Social capital has become a critical issue in agricultural development as it plays an important role in collective action, such as, management of common resources and collective marketing. Whilst literature exists on the role of social capital in the use and adoption of improved agricultural technology, such literature is fraught with issues of the measurement of social capital beyond membership of farmers in groups. We hypothesized that different types of social capital influence the adoption of soil management options differently. This study looked at the measurement of social capital, differentiating between the main types of social capital and employed factor analysis to aggregate indicators of social capital into bonding, bridging, and linking social...

The Intergovernmental Panel on Climate Change (IPCC) has identified a number of soil-management strategies that can be implemented to reduce GHG emissions. However, before deciding which of these strategies are most appropriate in any given situation, it is important to investigate how these strategies affect other aspects of sustainable development. For instance, some attempts to sequester carbon in the landscape could alter the soil&amp;#8217;s capacity to filter water. Alternatively, other strategies could unintentionally increase net energy consumption through greater fertilizer use. Focusing specifically on opportunities to implement soil-management strategies in the European Union (EU), we discuss the synergies and trade-offs of those strategies with...

Autores: Oliveira,Job T. de; Roque,Cassiano G.; Teodoro,Paulo; Montanari,Rafael.
ABSTRACT The common bean is widely cultivated in Brazil. In the 2016–2017 growing season, an experiment was carried out in a Typic Quartzipsamment (or Neossolo Quartzarênico) soil in the municipality of Cassilândia, MS, Brazil, with the aim of characterizing specific aspects of soil management, using a linear and spatial correlation between the irrigated yield of common beans and the chemical properties of the soil. Soil samples were collected from layers at depths 0.00–0.10 and 0.10–0.20 m, within a grid of 117 georeferenced points. A data analysis was carried out using statistical and geostatistical techniques. A multiple regression analysis showed that about 31% of the grain yield variability of the irrigated common bean crop could be attributed to the...

Autores: CRESPOLINI, M.; NASCIMENTO, P. P.
A carência de informações detalhadas sobre os solos brasileiros é um grande entrave para o desenvolvimento do país. Apenas 5% do território nacional conta com mapeamentos em escalas adequadas, dificultando ações para a promoção do desenvolvimento sustentável. Em 2020, isso começou a mudar com a implementação das ações do Programa Nacional de Levantamento e Interpretação de Solos no Brasil (PronaSolos). Para 2021, o desafio aumentou e esta importante política pública busca o apoio de parcerias, no modelo público-privado.

A produção de energia elétrica sustentável por meio da instalação das torres eólicas, no município de Casa Nova, BA, a exemplo de outras localidades, é uma realidade e, se por um lado produz uma energia limpa, por outro lado, necessita construir estradas vicinais cascalhadas, objetivando o transporte das referidas torres, que são constituídas por peças longas e bastante pesadas, que por sua vez exigem caminhões de grande porte. Para a pavimentação foram utilizadas seis jazidas prospectadas, aleatoriamente, dentro da área dos parques no município, que resultaram na retirada de toda avegetação de uma área total de 16,5 hectares, com exceção das espécies ameaçadas de extinção a exemplo do umbuzeiro (Spondias tuberosa Arr.),baraúna (Schinopsis brasiliensis) e...

Autores: KLEIN, M. A.; COSTA, F. de S.
O milho é uma das culturas mais versáteis na propriedade agrícola, característica que se deve aos seus múltiplos usos. É insumo básico nas cadeias produtivas de suínos e aves e também na bovinocultura de corte e leite, podendo ser utilizado como silagem. Na alimentação humana, pode ser consumido de forma in natura como milho verde ou seco, na elaboração de bolos e outros alimentos. Por fim, pode simplesmente ser comercializado após atingir seu ponto de colheita. No contexto da agricultura familiar, além de representar importante fonte de renda, o milho pode significar uma alternativa para garantir segurança alimentar.

ABSTRACT: Ultrasonic energy is a promising tool in soil science. Soil aggregates breakdown susceptibility may have a significant effect on a range of soil physical properties of agronomic importance such as physical properties and erodibility. Soil dispersion characteristics curves give important informations about soil aggregate stability, and are influenced by soil mineralogy, organic matter and soil use and management. Interpretation of dispersion curves and the use of dispersion index and normalized dispersion index for aggregate stability assessment and the use of these indexes to estimate soil erodibility in brazilian soils are discussed.

O solo é considerado elemento básico no que diz respeito a qualquer atividade agropecuária, sendo imprescindível o emprego de técnicas visando à melhoria de sua fertilidade e conservação de forma a torná-lo cada vez mais produtivo com sustentabilidade. Nos ambientes semiáridos, os solos tendem a ser mais susceptíveis a erosão, e o uso de práticas de manejo inadequadas, como queimadas, preparo do solo com grade aradora e plantio morro abaixo, vem piorando a situação. Uma das alternativas para sanar esse processo é o uso de sistemas agroecológicos, os quais buscam imitar os ecossistemas naturais, comumente considerados sustentáveis (Figura 1). No entanto, alguns aspectos em relação a manejo de água e solo carecem de informações. Para isso, elaborou-se esta...

Na criação tecnificada de suínos, muita preocupação tem sido atribuída ao destino final dos resíduos gerados por este sistema, principalmente na geração de fertilizantes orgânicos e sua aplicação no ambiente. No ano de 2010, foram abatidos, aproximadamente, 36,8 milhões de cabeças e espera-se que até o ano de 2020 este número aumente, com incremento na produção de 24% (MAPA, 2010). Assim, a demanda para o aproveitamento dos resíduos gerados na criação de suínos será cada vez maior, fazendo com que a pesquisa necessite desenvolver recursos tecnológicos que equalizem a relação produção/qualidade ambiental.

RESUMO: A compactação do solo foi avaliada e correlacionada com a produtividade de soja irrigada (safra 2006) sob plantio direto em dois solos: Latossolo Vermelho Amarelo textura média (LV) e Neossolo Quartzarênico (RQ) na região de Luis Eduardo Magalhães, Bahia, Brasil. Ensaios de campo e laboratório para determinação do Índice de Cone (IC) foram conduzidos, sendo ajustados modelos de IC em função de (conteúdo de água volumétrico), Ds (densidade do solo) e argila. Ensaios de laboratório proporcionaram modelos com R2 mais elevados. Para caracterização da compactação do solo com base no IC, é importante estabelecer as relações matemáticas entre IC e atributos do solo, como Ds e teor de argila. Tanto o LV quanto o RQ sob Cerrado apresentaram valores mais...

Manejo do solo para favorecer a manutenção da umidade.
Provedor de dados: 14
Autores: DEON, D. S.
A manutenção da umidade no solo é de suma importância para o desenvolvimento das culturas, embora seja um grande desafio para o semiárido, principalmente por causa das condições de clima e de solo. A temperatura e a insolação são elevadas, enquanto a umidade relativa do ar é baixa, resultando em altas taxas de evapotranspiração, as quais, associadas ao baixo índice pluviométrico, e à distribuição irregular das chuvas resultam em deficit hídrico na maior parte do ano. Além disso, as características comuns aos solos, em geral arenosos e pouco profundos, são fatores que limitam sua capacidade de armazenamento de água. Assim, estratégias de manejo que possam favorecer à manutenção da água no solo são de grande importância para os cultivos dependentes de chuva...

"ESCOLHA inteligente" da forrageira viabiliza intensificação da pecuária na Amazônia.
Provedor de dados: 14
O uso indiscriminado de uma determinada cultivar forrageira em uma área que não é a mais propícia para o seu desenvolvimento pode retardar a consolidação da pecuária intensiva, como foi o caso pelo qual passaram alguns produtores do Bioma Amazônico. Pecuarista deve escolher a cultivar de olho em uma pastagem perene, já que características do bioma inviabilizam as reformas frequentes.

Autores: FERREIRA, A. C. de B.; BORIN, A. L. D. C.; LAMAS, F. M.; FERREIRA, G. B.; RESENDE, A. V. de.
O Cerrado brasileiro, em geral, são naturalmente ácidos e intemperizados, apresentando níveis tóxicos de alumínio (Al3+), baixos níveis de saturação por bases trocáveis, baixa capacidade de troca de cátions (CTC) e reduzidos teores de matéria orgânica, além de reduzida disponibilidade de nutrientes, com exceção de ferro e manganês (Lopes; Guilherme, 2016). Não obstante essas características, são solos profundos, com condições favoráveis à mecanização e respondem às correções químicas, viabilizando a produção agrícola rentável. A região do Cerrado contribui em grande proporção para a produção nacional de soja, de milho e de quase todo algodão (98%) produzido no País (Conab, 2021). Mas, para que isso acontecesse, os solos precisaram ser corrigidos...

No Semiárido brasileiro, a maioria dos agricultores pratica agricultura dependente de chuva, e vem sofrendo com perdas de sua produtividade por causa da ausência e insuficiência das chuvas e manejo inadequado do solo e água. As políticas públicas denominadas ?programa terra pronta? praticadas por governos estaduais e municipais constituem-se em um agravante à conservação de solo, pois apesar de enfatizar que vai fazer a aração, o preparo do solo, na maioria das vezes, é efetuado com grades aradoras, que deixam os solos vulneráveis à erosão.

Aggregation can suffer permanent or temporary changes to cyclical variations induced by management practices for soil and plant growth. The study evaluated the temporal and spatial variation of the stability of water stable aggregates and its relationship with the organic matter content in an Hapludalf in Santa Maria municipality, Rio Grande do Sul State, Brazil. The treatments were four tillage systems for deployment of Eucalyptus grandis: no-tillage, chisel, chisel tillage plus harrowing and rotary tiller. Soil samples were collected in the layer of 0.00 to 0.05 m for determination of the density, and stability in water of stable organic matter aggregates contents of the soil. Chisel, chisel tillage plus harrowing and rotary tiller resulted in lower...

Autores: Beutler,Amauri Nelson; Centurion,José Frederico; Silva,Alvaro Pires da; Centurion,Maria Aparecida Pessôa da Cruz; Leonel,Cristian Luarte; Freddi,Onã da Silva.
The research aimed to evaluate machine traffic effect on soil compaction and the least limiting water range related to soybean cultivar yields, during two years, in a Haplustox soil. The six treatments were related to tractor (11 Mg weight) passes by the same place: T0, no compaction; and T1*, 1; T1, 1; T2, 2; T4, 4 and T6, 6. In the treatment T1*, the compaction occurred when soil was dried, in 2003/2004, and with a 4 Mg tractor in 2004/2005. Soybean yield was evaluated in relation to soil compaction during two agricultural years in completely randomized design (compaction levels); however, in the second year, there was a factorial scheme (compaction levels, with and without irrigation), with four replicates represented by 9 m² plots. In the first year,...

Autores: Yagi,Renato.
Abstract: The objective of this work was to evaluate the residual effects of occasional soil tillage in a 17-year-old, no-tillage system, associated with liming and nitrogen fertilization, on the crop yields and chemical properties of a very clayey Oxisol in the South of Brazil. A randomized complete block design in split-split plots was used, with two soil managements (with or without plowing), two liming treatments (with or without the required dose to raise base saturation to 70%), five N doses applied on side-dress (0, 1, 2, 4, and 6 times the recommended amounts), and four replicates. A rotation system was used with corn and soybean in the summer, and with wheat and black oats in the winter. The residual effects of occasional soil tillage in a...

The objective of this work was to evaluate the relationship between soil chemical and biological attributes and the magnitude of cuts and fills after the land leveling process of a lowland soil. Soil samples were collected from the 0 - 0.20 m layer, before and after leveling, on a 100 point grid established in the experimental area, to evaluate chemical attributes and soil microbial biomass carbon (MBC). Leveling operations altered the magnitude of soil chemical and biological attributes. Values of Ca, Mg, S, cation exchange capacity, Mn, P, Zn, and soil organic matter (SOM) decreased in the soil profile, whereas Al, K, and MBC increased after leveling. Land leveling decreased in 20% SOM average content in the 0 - 0.20 m layer. The great majority of the...

Abstract Human pressure on ecosystems has undesirable impacts on human well-being. After the Millennium Project, much interdisciplinary research has been developed worldwide aiming to understand these impacts on ecosystem flows and processes, and to learn about the costs and the benefits of ecosystem services for production. Soil provides many ecosystem services, since its multi-functionality is the basis for food production, water filtration, nutrient cycling, and other goods essential to life. This article presents the main concepts and classifications of soil ecosystem services and of its functions; the indicators and the methods for assessment, modeling, and valuation of ecosystem services; some recent applications to assess and evaluate impacts of...

Weeds occurrence and importance under distinct intercropping systems
Provedor de dados: 87
Autores: Concenço,G; Ceccon,G; Schwerz,F; Fonseca,I.C; Leite,L.F.
Intercropping systems involving corn are often subjected to stress caused by weeds, which usually result in 30-70 per cent yield loss when no control practice is applied. This study aimed to assess the composition of weed communities due to soil coverage, at neighboring areas submitted to distinct soil managements. The soil was collected at field and the study was conducted under a greenhouse in three steps: (1) weeds composition and importance within each treatment; (2) comparison between treatments (distinct crop and intercropping managements); (3) infestation in the area as a whole. The weed composition in the short term is influenced by the management of the area, but this shift requires some more years to be reflected at the soil seed bank. Some weed...

Brachiaria ruziziensis and herbicide on the yield of upland rice
Provedor de dados: 87
Autores: Nascente,A.S.; Guimarães,C.M.; Cobucci,T.; Crusciol,C.A.C.
The correct management of cover crops in no-tillage aims to obtain greater benefits with its introduction in agricultural systems. The use of forage species such as Brachiaria, due to the large amount of biomass and for persisting longer on the ground, has become a good option. In this sense, an important point is the time interval between the cover desiccation with glyphosate and planting of rice in order to obtain higher operating income in the sowing, greater availability of nutrients, greater presence of straw on the soil surface, and lower release of possible allelopathic substances. The objective of this study was to assess the effect of the management of B. ruziziensis, with or without herbicide, preceding the crop planting, in the yield components...

SOIL, NUTRIENT, AND WATER MANAGEMENT SYSTEMS USED IN U.S. CORN PRODUCTION
Provedor de dados: 31
Autores: Christensen,   Lee A.
Corn production uses over 25 percent of the Nation's cropland and more than 40 percent of the commercial fertilizer applied to crops. Thus, corn farmers' choices of soil, nutrient, and water management systems can have a major impact not only on their own profitability, but also on the environment. If sound economic and environmental choices are to be encouraged, it may help to assess relationships between operator and farm characteristics and the adoption of management techniques by corn farmers. Data from the 1996 Agricultural Resource Management Survey (ARMS) of U.S. corn farms and producers are analyzed for this purpose, supplemented by a literature survey on factors that influence corn farm management choices. Relationships were found between certain...

ABSTRACT: Organic fertilization effect on physical-chemical properties in no-tillage systems in tropical soils has been widely investigated, but little is known about the effects of this practice on the mineralogy of the clay fraction. This study aimed to evaluate the clay-fraction mineralogy of two subtropical soils, fertilized with organic residues in long-term no-tillage systems. An Alfisol fertilized with 0, 40, and 80 m3 ha-1 yr-1 pig slurry was evaluated for eight years, and an Oxisol with 0, 8, and 16 Mg ha-1 of wood shavings with pig slurry, for six years. Soil samples from the layers 0.00-0.04, 0.04-0.08, and 0.16-0.20 m were collected and subjected to chemical extractions with DCB and oxalate, X-ray diffractometry, and thermal analysis. No...

In Brazil, grazing mismanagement may lead to soil and pasture degradation. To impede this process, integrated cropping systems such as silvopasture have been an effective alternative, allied with precision agriculture based on soil mapping for site-specific management. In this study, we aimed to define the soil property that best sheds light on the variability of eucalyptus and forage yield. The experiment was conducted in the 2011/12 crop year in Ribas do Rio Pardo, Mato Grosso do Sul State, Brazil. We analyzed linear and spatial correlations between eucalyptus traits and physical properties of a Typic Quartzipsamment at two depths (0.00-0.10 and 0.10-0.20 m). For that purpose, we set up a geostatistical grid for collection at 72 points. Gravimetric...

Winter cover crops are sources of C and N in flooded rice production systems, but very little is known about the effect of crop residue management and quality on soil methane (CH4) and nitrous oxide (N2O) emissions. This study was conducted in pots in a greenhouse to evaluate the influence of crop residue management (incorporated into the soil or left on the soil surface) and the type of cover-crop residues (ryegrass and serradella) on CH4 and N2O emissions from a flooded Albaqualf soil cultivated with rice (Oryza sativa L.). The closed chamber technique was used for air sampling and the CH4 and N2O concentrations were analyzed by gas chromatography. Soil solution was sampled at two soil depths (2 and 20 cm), simultaneously to air sampling, and the...

Provedor de dados: 90
Autores: Tavares Filho,João; Tessier,Daniel.
Different management systems tend to modify soil structure and porosity over the years. The aim of this study was to study modifications in the morphostructure and porosity of dystroferric Red Latosol (Oxisol) under conventional tillage and no-tillage over a 31- year period. The study began with the description of soil profiles based on the cropping profile method, to identify the most compact structures, define sample collection points for physical and chemical analysis, and determine the water retention curve. A forest soil profile was described and used as reference. The results showed that, under conventional tillage, the microaggregate structure of the Oxisol was fragmented between 0 and 0.20 m, and compact (bulk density = 1.52 Mg m-3) in the...

Autores: Tiecher,Tales; Santos,Danilo Rheinheimer dos; Kaminski,João; Calegari,Ademir.
The cultivation of crops with different capacity of P uptake and use under long-term soil tillage systems can affect the distribution of P cycling and inorganic forms in the soil, as a result of higher or lower use efficiency of P applied in fertilizers. The purpose of this study was to evaluate the effect of long-term cultivation of different winter species under tillage systems on the distribution of inorganic P forms in the soil. In 1986, the experiment was initiated with six winter crops (blue lupin, hairy vetch, oat, oilseed radish, wheat and fallow) on a Rhodic Hapludox in southwestern Paraná, under no-tillage (NT) and conventional tillage (CT). The application of phosphate fertilizer in NT rows increased inorganic P in the labile and moderately...

This research aimed (i) to determine indicators of the state and function of the porous system, (ii) to use them to derive a global index to characterize the soil physical quality, and iii) to establish a reference pore-size distribution curve for Mollisols from the province of Santa Fe (Argentina). Sixty water retention curves (WRC) of A and B horizons of Mollisols, with clay varying between 119 and 538 g kg−1, organic matter between 5 and 40 g kg−1, and soil bulk density between 1.09 and 1.49 Mg m−3, were used. The indicators measured were: pore size...

Aggregate distribution, stability and release of water dispersible clay for two subtropical Oxisols
Provedor de dados: 63
Autores: Azevedo,Antonio Carlos de; Schulze,Darrel Gene.
The behavior of a soil regarding the dispersion and aggregation of its particles is very important for the development of environmental and agricultural soil functions. This study was conducted to determine how aggregate distribution and stability are impacted by land uses and how the release of Water Dispersible Clay (WDC) relates to disaggregation in Oxisols from subtropical Brazil. Samples from two Oxisols, collected at three depths from sites under no-tillage (NT), conventional tillage (CT) and native vegetation (NV) land uses were shaken in 250 mL plastic bottles for intervals up to 27 hours. The mass of aggregates was measured in five size classes ranging from 53 to 2000 µm. Most aggregates larger than 500 mm disappeared during the first 7.5 hours of...

Pedologic alterations after long-term sugar cane (Saccharum officinarum) cropping cycles under traditional soil management systems were studied on a farm in Bariri, SP, Brazil. A toposequence was established to evaluate the effects of the soil position in the relief in changing soil physical attributes. Morphological field descriptions and laboratory analyses were carried out on vertical profiles of the upper, middle and lower thirds of a Typic Haplorthox slope. Soil bulk density and macroporosity changed along the toposequence reflecting on soil hydrodynamics, especially in the lower slope parts. At sites with high clay levels, empty spaces were filled forming block shaped structures together with the micro-aggregate structure. The intensive cultivation...

Soil organic matter of a humic Oxisol has been characterized by analyzing litter and soil lipid composition under vegetal covers (coffee, pasture and fragment of native forest). Soil and litter samples were collected from each site at two depths (0-10 and 60-100 cm). Lipid composition was determined by gas chromatography-mass spectrometry (CG-MS). In the solvent extracts of the soil lipids, even-numbered n-alkanoic acids in the range of C16-C32 indicate a soil organic matter input from higher plant waxes. The major compound classes in both the soil and the litter included saturated n-alkanoic acids, with average values in the total spectrum of 58 and 53%, respectively Clear differences in lipid composition were found between the topsoil and subsurface....

Autores: Dafonte,Jorge Dafonte; Guitián,Montserrat Ulloa; Paz-Ferreiro,Jorge; Siqueira,Glécio Machado; Vázquez,Eva Vidal.
Nutrient maps based on intensive soil sampling are useful to develop site-specific management practices. Geostatistical methods have been widely used to determine the spatial correlation and the range of spatial dependence at different sampling scales. If spatial dependence is detected, the modelled semivariograms can then be used to map the interested variable by kriging, an interpolation method that produces unbiased estimates with minimal estimation variance. The objectives of this paper were to examine and to map the spatial distribution of the micronutrients Cu, Zn, Fe and Mn on an agricultural area in Galicia, Spain, under European Atlantic climatic conditions. The ordinary kriging was first used to determine the values for the non-sampled locations,...

Autores: Araujo,Izabel Cristina Leinig; Dziedzic,Maurício; Maranho,Leila Teresinha.
The aim of this work was to study ecotechnology for the management of degraded areas originally covered by the Atlantic Rainforest and located at the coordinates 25º31'50''S, 9º09'30''W. The area included 12 islands, each consisting of six jute bags with 20 kg of substrate (cattle manure and soil transposed from forest fragments). In six of these bags, native plants and seeds were also included. Six additional islands were selected randomly in the vicinity as the control. The process of evaluation was monitored through the chemical and granulometric soil analysis and surveys of survival, biometrics, floristic and phytosociological vegetation. An improvement in soil properties was observed where the model was implemented, which could be attributed to the...

Provedor de dados: 58
Autores: Balota,Elcio Liborio; Kanashiro,Miriam; Colozzi Filho,Arnaldo; Andrade,Diva Souza; Dick,Richard Peter.
Agricultural practices that reduce soil degradation and improve agricultural sustainability are needed particularly for tropical/subtropical soils. No-tillage planting causes minimal soil disturbance and combined with crop rotation may hold potential to meet these goals. Soil enzyme activities can provide information on how soil management is affecting the potential to perform the processes in soils such as decomposition and nutrient cycling. Soil enzyme activities were investigated in a split-plot experiment (3 replications) where tillage (no till and conventional) was the main plot and crop rotation (soybean/wheat, S/W; maize/wheat, M/W or cotton/wheat, C/W) was the subplot. The experiment was established in 1976 in southern Brazil. Soil samples were...

Autores: Souza,Renata Carolini; Cantão,Maurício Egídio; Nogueira,Marco Antonio; Vasconcelos,Ana Tereza Ribeiro; Hungria,Mariangela.
ABSTRACT The soil represents the main source of novel biocatalysts and biomolecules of industrial relevance. We searched for hydrolases in silico in four shotgun metagenomes (4,079,223 sequences) obtained in a 13-year field trial carried out in southern Brazil, under the no-tillage (NT), or conventional tillage (CT) managements, with crop succession (CS, soybean/wheat), or crop rotation (CR, soybean/maize/wheat/lupine/oat). We identified 42,631 hydrolases belonging to five classes by comparing with the KEGG database, and 44,928 sequences by comparing with the NCBI-NR database. The abundance followed the order: lipases &gt; laccases &gt; cellulases &gt; proteases &gt; amylases &gt; pectinases. Statistically significant differences were attributed to the...

Effect of Agricultural Intervention on the Spatial Variability of some Soils Chemical Properties in the Eastern Plains of Colombia
Provedor de dados: 117
Autores: Camacho-Tamayo,Jesús H; Luengas,Carlos A; Leiva,Fabio R.
Growing demand for food exerts pressure on natural resources and may lead to the expansion of agricultural frontiers in developing countries. Most of this pressure appears in tropical zones, in native savannahs, with naturally infertile soils prone to degradation. Crop management in these regions is based on generalized estimates, leaving aside the inherent soil variability, leading to low production efficiency and high risk of environmental damage. This study aims at determining the spatial variability of some chemical properties, including organic carbon, pH, exchangeable acidity, exchangeable aluminum, P, Ca, Mg, K and Na for two Oxisols with different levels of agricultural intervention, in Puerto Lopez, Colombia, in order to identify guidelines for...

ABSTRACT:  Intensification of soil compaction process under no-tillage (NT) is motivating the search for alternatives to mitigate soil compaction state. This study evaluated changes in soil physical and hydraulic properties caused by seeder with fertilizer shanks at different depths compared with the double discs lagged seeder, to investigate the possibility of soil decompaction by sowing under NT in southern Brazil. The study was conducted in a clayed Oxisol, for 27 years under NT. Treatments were three planting mechanisms: S0.10m: cutting disc combined with shank acting to 0.10m depth; S0.15m: cutting disc combined with shank acting to 0.15m depth and, D0.07m: double discs lagged acting to 0.07m depth in an experimental randomized block design with four...

The knowledge of the water content in the soil profile is essential for an efficient management of crop growth and development. This work aimed to use geostatistical techniques in a spatio-temporal study of soil moisture in an Oxisol in order to provide that information for improved crop management. Data were collected in a coffee crop area at São Roque de Minas, in the upper São Francisco River basin, MG state, Brazil. The soil moisture was measured with a multi-sensor capacitance (MCP) probe at 10-, 20-, 30-, 40-, 60- and 100-cm depths between March and December, 2010. After adjusting the spherical semivariogram model using ordinary least squares, best model, the values were interpolated by kriging in order to have a continuous surface relating depth x...
