Visou-se, neste trabalho, determinar as perdas de solo, água e nutrientes em um Argissolo Vermelho-Amarelo submetido a quatro diferentes padrões chuva simulada. O estudo foi conduzido no Campo Experimental da Embrapa-Agrobiologia, localizado município Seropédica, RJ, consistiu na aplicação chuvas simuladas com caracterizados como avançado (AV), intermediário (IN), atrasado (AT) constante (CT), uma área amostral 0,80 m largura por 1,0 comprimento. As tiveram duração 60 min lâmina total...
The objective of this work was to evaluate the initial growth assai seedlings (Euterpe oleraceae) in response shading and slow release fertilizer. experiment conducted at Embrapa Acre a randomized block design using 4 × 5 factorial scheme with three replicates 10 plants per plot. treatments consisted four shade environments (20%, 30%, 50% 75%) five levels fertilizer (0.0, 2.5, 5.0, 7.5 10.0 kg m–3). following characteristics were evaluated: plant height, number leaves, stem diameter, leaf...
Este trabalho foi realizado com o objetivo de determinar as perdas solo e água em um Argissolo Vermelho-Amarelo, submetido a quatro diferentes padrões precipitação chuva simulada duas condições cobertura: área descoberto palhada após plantio milho. O experimento conduzido no Campo Experimental da Embrapa-Agrobiologia, localizado município Seropédica-RJ, consistiu na aplicação chuvas simuladas padrões, caracterizados como avançado (AV), intermediário (IN), atrasado (AT) constante (CT), uma...
This paper describes TerraHidro that is a distributed hydrologic modeling platform. general purpose water resources system presents new concept to represent flows based on graph structure, in the geographic information (GIS) context. The drainage extractions and Amazonian basin delimitations using have been compared with ArcGis Hydro Tools regarding show availability of sub basins, called Xingu, Purus Tapajos are presented.
As plantas daninhas são consideradas como um dos principais problemas nas culturas, pois interfere no rendimento, qualidade do produto e na rentabilidade da atividade agrícola. O adequado manejo destas depende, primeiramente, identificação das espécies presentes área. levantamento fitossociológico é uma importante ferramenta para auxiliar escolha melhor método de controle quando realizá-lo. Objetivou-se com este estudo foi realizar em monocultivo açaizeiro solteiro município Rio Branco,...
This region has the particularity of, at same time, coexisting with sporadic floods and scarcity of water. situation requires complex studies involving water resources based on runoff rain waters courses rivers. For extraction drainage was carried out by using system for hydrological modeling treatment TerraHidro, developed INPE's Image Processing Division. uses PFS method drainage, which provided good results, enabling reduction time spent manual editing errors. TerraHidro a tool called...
This paper presents TerraHydro, a Distributed Hydrological System created to develop hydrographic basin water flow GIS applications. TerraHydro proposes different computational representation for dealing with in These applications involve the concept of local flow, extracted from terrain, which is basis most spatially explicit distributed hydrological models. Different computer structures based on regular grids, triangular irregular networks, contour lines, and polygon tessellations have...
Fruit of a collaboration between two international research institutions, the paper presents ongoing activity to foster provisioning South America drainage datasets, by means Open Data principles and tools. We discuss how those environmental data sources may be published shared for benefit public private organizations advantage multi-sectorial disciplines. The aim is adopt, either emerging well-established, tools or practices supporting production, publication re-use. former results achieved...
Croton lechleri (dragon's blood) is a forest species used by traditional Amazonian communities for medicinal purposes, with potential use in degraded area recovery and as source of additional income some communities. However, silvicultural studies on this are scarce. This study aimed to evaluate the influence substrates shading levels seedling emergence initial development C. seedlings. A completely randomized statistical design four replications was used, arranged 7 x 5 factorial setup...
Cratylia argentea (cratília) is a neo-tropical leguminous plant with high resprouting ability, showing great potential as both an animal feed and to fertilize the soil through its N-fixing ability. During scientific expeditions carried out in 2016 identify collect germplasm different states of Brazil, Terra Ronca State Park (PETeR) stood conservation area for this species. There, cratília well adapted dry season, retaining green leaves even during extended periods was found develop shrub or...
Objetivou-se avaliar o efeito da aplicação de ácido indolbutírico (AIB) e extrato tiririca em miniestacas apicais, medianas basais aceroleira para fins produção mudas. As miniestacas, padronizadas 3 cm altura, foram coletadas parte mediana das plantas-matrizes ramos 15 cm. O foi obtido dos tubérculos (Cyperus rotundus). delineamento experimental inteiramente casualizado esquema fatorial x 3, sendo três tipos dois indutores enraizamento a testemunha. Conduziu-se experimento duas etapas: na...
This paper presents a methodology to determine the permanent protected areas (PPA) of riverbanks. The amount area depends on river width and size each property which have running through or by it, as stated in Brazilian forest code law. rules are: 30 meters for rivers up 10 wide, 50m 100m 50 200m 200 600m 500m, wider than 600m. steps PPA buffer along are (1) construction triangular grid (TIN) that constitutes basis calculation central axis river; (2) definition points representing river,...
This work establishes a semi-automatic methodology to define and evaluate the Environmental Protection Areas (EPA), in Paraíba River Basin, Brazil, taking account land use water quality. The development of this started from capitation point Guaratingueta city located on stream that runs through city. From ASTER GDEM data drainage network basin catchment was automatically extracted. Landsat images for dates 1989, 2001 2014 were digitally classified uses mapped, considering area permanent...
O Brasil é um dos maiores produtores mundiais de abacaxi, entretanto, problemas relacionados ao manejo da cultura, como baixa densidade plantas, alta incidência ervas daninhas e uso inadequado do solo têm comprometido o desenvolvimento vegetativo gerado perdas produtividade redução qualidade frutos. objetivo estudo foi avaliar aumento das densidades plantio cobertura sobre a ocorrência plantas daninhas, acúmulo nutrientes na folha “D” abacaxizeiro, cultivar BRS 'RBO'. experimento conduzido...
