Abstract Projected change in forage production under a range of climate scenarios is important for the evaluation impacts global on pasture‐based livestock systems Brazil. We evaluated effects regional trends Panicum maximum cv. Tanzânia production, predicted by an agro‐meteorological model considering sum degree days and corrected water availability index. Data from Brazilian weather stations (1963–2009) were considered as current (baseline), future scenarios, based contrasting terms...
Farmers in the Brazilian Cerrado are increasing grain production by cultivating second crops during same crop growing season. The release of PlanetScope (PS) satellite images represents an innovative opportunity to monitor double cropping production. In this study, we analyzed potential six PS monthly mosaics from 2021/2022 season discriminate areas municipality Goiatuba, Goiás State, Brazil. four multispectral bands were converted into normalized difference vegetation index (NDVI), enhanced...
Agricultural intensification practices have been adopted in the Brazilian savanna (Cerrado), mainly transition between Cerrado and Amazon Forest, to increase productivity while reducing pressure for new land clearing. Due growing demand more sustainable practices, accurate information on geospatial monitoring is required. Remote sensing products artificial intelligence models pixel-by-pixel classification great potential. Therefore, we developed a methodological framework with spectral...
The Brazilian Cerrado (tropical savanna) is the second largest biome in South America and main region country for agricultural production. Altitude crucial information decision-makers planners since it directly related to temperature that conditions, example, climatic risk of rainfed crop plantations. This study analyzes conformity two freely available digital elevation models (DEMs), NASADEM Merged Digital Elevation Model Global 1 arc (NASADEM_HGT) version Advanced Land Observing Satellite...
The Brazilian Savanna presents a complex agricultural dynamic and cloud cover issues; therefore, there is need for new strategies more detailed monitoring. Using hierarchical classification system, we explored the Harmonized Landsat Sentinel-2 (HLS) dataset to detect soybean in western Bahia, Brazil. Multispectral bands (MS) vegetation indices (VIs) from October 2021 March 2022 were used as variables feed Random Forest models, performances of complete HLS time-series, HLSS30 (harmonized...
O presente trabalho objetivou aplicar os conceitos de geoestatística e geoprocessamento para a obtenção zonas manejo uma área pastagem capim Tanzânia, em São Carlos - SP, delimitação unidades aplicação calagem adubação, com base no melhor método interpolação. Com resultados análise solo foram realizadas análises geoestatísticas avaliação da dependência espacial dos atributos químicos. Os mapas obtidos pelo interpolação por Krigagem Ordinária definição das foi realizada meio lógica fuzzy. A...
Os sistemas de produção animal no Semiárido brasileiro podem ser vulneráveis às mudanças climáticas. Cenários futuros para a Brachiaria brizantha, Panicum maximum, Cenchrus ciliaris e Opuntia fícus indica foram analisados identificação áreas mais vulneráveis. A partir dos modelos já disponíveis, identificadas algumas maior vulnerabilidade, o que possibilitou indicação alternativas adaptação mitigação possíveis impactos negativos das climáticas globais sobre do brasileiro. O desenvolvimento...
Abstract Sodium fluorescein ( SF ) was evaluated and validated as an internal marker in cattle for the location of urine patches pastures. Three trials were carried out aiming at following: evaluating effect dilution volume application on fluorescence environment; testing dosages duration excretion administered orally to cattle; validating methodology use The tested beef kept pastures under three grazing systems: degraded pasture extensive management (De), intensively managed dryland with...
Este estudo analisa a acurácia posicional vertical dos dados coletados do modelo digital de elevação (MDE) programa Copernicus DEM, denominado COP-30, baseado no Padrão Brasileiro Exatidão Cartográfica para Produtos Cartográficos Digitais (PEC-PCD), com as altitudes elipsoidais fornecidas por 317 estações referência Sistema Geodésico localizadas estado Goiás e Distrito Federal. O PEC-PCD definiu tolerâncias erro acordo oito escalas diferentes (de 1:1000 1:250.000) quatro classes qualidade...
Climatic risk zoning allows the identification of areas low reduced crop productivity due to climatic events. In Brazil, losses agriculture climate are mainly caused by drought. The objective this research was determine for corn and palisade grass cultivated in integrated crop-livestock systems Sao Paulo state. Corn varieties characterized a 120-day growing cycle soil with three different water holding capacities (sandy, medium clayey soils) were considered. A daily balance model used...

Campos Bernardi, Giovana Maranhao Bettiol, Celia Regina Grego, Ricardo Guimaraes Andrade, Ladislau Marcelino Rabello e Yassushi Inamasu, tem objetivo apresentar as ferramentas discutir elas podem auxiliar no melhoria eficiencia uso nutrientes. Durante os ultimos 30 anos, a producao graos Brasil cresceu uma taxa 4,6% ano, enquanto area plantada apenas 1,7% ano. Essa...
Abstract: The objective of this work was to evaluate the spatial and temporal variability dry matter yield irrigated corn for silage, as well its economic return. study conducted in an silage field 18.9 ha municipality São Carlos, state Paulo, Brazil. three crop seasons, normalized indexes, production cost, profit, soil electrical conductivity (EC) were modeled using semivariograms. Yield maps obtained by kriging, management zones mapped based on average yield, index, EC. results showed a...
As alterações antrópicas no meio ambiente têm promovido a redução dos espaços naturais, agravando os problemas ambientais e comprometendo sustentabilidade ecossistemas. Este trabalho objetivou diagnosticar bacia do Médio Araguaia em termos de susceptibilidade à erosão, perda solos vulnerabilidade natural para subsidiar ações restauração ecológica. seguintes variáveis foram consideradas: (i) mapas uso ocupação da terra período 1985-2020; (ii) solos, geologia geomorfologia, na escala...
The objective of this work was to analyze future scenarios for palisade grass yield subjected climate change the state São Paulo, Brazil. An empirical crop model used estimate yields, according growing degree-days adjusted by one drought attenuation factor. Climate data from 1963 2009 23 meteorological stations were current conditions. Downscaled outputs two general circulation models project 2013-2040 and 2043-2070 periods, considering contrasting temperature atmospheric CO2 concentration...
O sensoriamento remoto (SR), amplamente utilizado em diferentes áreas do conhecimento, também pode ser aplicado para o manejo de sistemas agropecuários. Entre as técnicas aplicadas sobre os produtos SR, se destacar uso índices vegetação, que buscam relacionar variações comportamento espectral medido através imagens com parâmetros biofísicos das plantas. E a qualidade dos resultantes depende diretamente da precisão utilizadas. Nesse sentido, este trabalho teve como objetivo comparar vegetação...
No intuito de contribuir para um desenvolvimento agrícola e pecuário sustentável no estado Goiás, este artigo analisa as áreas prioritárias a recuperação pastagens vale do Araguaia, uma região especializada nesta atividade. Para tanto, foram utilizadas seguintes variáveis: mapa degradação (base Pastagem.org / LAPIG), aptidão vulnerabilidade ambiental, requisitos analisados em conjunto Sistema Informações Geográficas. Nossos resultados indicam existência mais 460 mil hectares pastagem aptos à...
