Carbon dioxide (CO2) in the Earth's atmosphere is a significant greenhouse gas and plays pivotal role shaping carbon dynamics of specific regions. Here, we have examined spatio-temporal variations atmospheric CO2 Bihar region India provided critical information regarding climate change mitigation. NASA's Orbiting Observatory-2 (OCO-2) satellite retrieved dry air column average concentrations (XCO2) datasets (2015-2021) are used to analyse hot/cold spots, anomalies, moments, their...
The increase of human activities across different regions Brazil has impacted biodiversity loss and water availability, negatively affecting natural resources, as well social economic factors, especially in the Amazon-Cerrado transition region. aim this work was to analyze changes land use cover from 1986 2022, project a scenario for year 2034 region, Maranhão, Brazil. study conducted municipality Chapadinha, Eastern Maranhão Mesoregion. Annual Land Use Cover Mapping Project (MAPBIOMAS) used...
The fires and biomass burning are responsible for affect ecosystem processes in a wide range of biomes at regional global scales. In Brazil, the state Mato Grosso is one most affected by occurrence forest fires. Thus, this study aims to quantify long-term changes temporal spatial patterns fire their effect on gross primary productivity (GPP) Grosso, considering that compose it. images used were acquired satellite Terra Aqua combined product MCD64A1.006, monthly resolution 500m Moderate...
Soil macrofauna organisms are recognized as ecological indicators of soil management practices. Sugarcane monoculture can have negative impacts on soil, including biodiversity loss, which should be evaluated. In that sense, the aim this was to determine diversity under sugarcane (Saccharum spp.) annual growth cycle (2012-2013) comparing two different natural vegetation areas (Sandbank and Atlantic forest). The study located at Usina Santa Teresa in Goiana municipality, Zona Mata Norte...
The recent studies of the variations in atmospheric column-averaged CO
Vast montado areas are threatened by degradation, as the result of a long history land use changes. Since improved pastures have been installed aiming soil quality improvement and system sustainability, it is crucial to evaluate effects these management changes on organic matter status biological activity, indicators. Therefore, 35-yr old pasture natural were studied, considering areas beneath tree canopy in open. Total C, total N, hot water soluble (HWS) particulate (POM)...
ABSTRACT In the Amazon-Cerrado ecotone, increased costs from non-organic inputs and transportation render substrates more expensive, prompting use of decomposed biomass native palm stem for seedlig production. The study was carried out with objective evaluate physicochemical characteristics babassu palms (BDB), carnauba (BDC), buriti (BBU) compared to commercial substrate (SC) via multivariate analysis. This employed a database comprising 90 substrates, obtained Maranhão, Brazil farms. These...
Barley (Hordeum vulgare L.) is a significant cereal globally, widely used in human and animal food. Furthermore, it has strong influence on genotype-by-environment interactions, being considered highly adaptable crop. This study aimed to estimate the parameters of adaptability stability for 17 barley genotypes, compared with two controls (BRS 180 BRS 195) grown under irrigation Cerrado. The experiments were conducted from 2017 2020, May September, different experimental areas Embrapa Federal...
Remote sensing has proven to be a vital tool for monitoring and forecasting the quality yield of crops. The utilization innovative technologies such as Solar-Induced Fluorescence (SIF) satellite measurements column-averaged CO2 (xCO2) can enhance these estimations. SIF is signal emitted by crops during photosynthesis, thus indicating photosynthetic activities. concentration atmospheric critical factor in determining efficiency photosynthesis. aim this study was investigate correlation...
The low natural fertility of tropical soils and the mineralogy almost dominated by iron aluminum oxides limit availability phosphorus (P) to plants, causing negative impacts on soybean yield. Objective was evaluate effect phosphate fertilization with different maximum adsorption capacities (PAC) in development. experiment carried out under greenhouse conditions, using Red-yellow Latosol (RYL) a Typic Hapludalf (TH) soil as substrate. analyses were performed completely randomized experimental...
Brazil stands out worldwide for its high grain production in areas of direct sowing. The objective this study was to simulate and assess the relationship soil organic carbon content nitrogen, crop yield, biomass two sequences under no-tillage system a subtropical region São Paulo, Brazil, using CSM-CROPGRO-Soybean CSM-CERES-Maize models. modeling carried considering meteorological conditions Jaboticabal, SP, Brazil. treatments consisted combining summer crops (maize soybean) with maize...
