The mapping of soil attributes provides support to agricultural planning and land use monitoring, which consequently aids the improvement quality food production. Landsat 5 Thematic Mapper (TM) images are often used estimate a given attribute (i.e., clay), but have potential model many other attributes, providing input for applications. In this paper, we aim evaluate Bare Soil Composite Image (BSCI) from state São Paulo, Brazil, calculated multi-temporal dataset, study its relationship with...
In addition to the largest existing expanse of tropical forests, Brazilian Amazon has among area mangroves in world. While recognized as important global carbon sinks that, when disturbed, are significant sources greenhouse gases, no studies have quantified stocks these vast mangrove forests. this paper, we total ecosystem and salt marshes east mouth River, Brazil. Mean were 257 Mg C ha −1 while those ranged from 361 746 . Although aboveground mass was high relative many other forests (145...
The search for tools to perform soil surveying faster and cheaper has led the development of technological innovations such as remote sensing (RS) so-called spectral libraries in recent years. However, there are no studies which collate all RS background demonstrate how use this technology classification. present study aims describe a simple method classify soils by morphology spectra associated with quantitative view (400-2,500 nm). For this, we constructed three libraries: (i) one model...

Seagrass meadows are considered one of the most important and valuable ecosystems on planet, but also threatened. Missing knowledge about their existence subtidal nature main reasons for lack information seagrass soils, especially in Brazil other tropical areas. This study discussed paradoxical subaqueous with a view to stimulate research soil properties meadows. short communication provides ecosystem first descriptions soils along Brazilian Coast, marked by gleyzation, sulfidization,...
Seasonality and crab activity affects the nutrients physicochemical parameters in mangrove soils, thus, affecting emissions of greenhouse gases, such as nitrous oxide (N2O). Climate change may intensify rainfall and/or enhance droughts, mangroves associated biota. Crabs are natural soil bioturbators responsible for aeration turnover. We evaluated effect Ucides cordatus on N2O from soils under a semiarid climate Northeastern Brazil. Soil gas samples were collected over rainy dry seasons...
Minimizing environmental impacts and increasing crop productivity depend mainly on the knowledge of chemical, physical mineralogical characteristics soil attributes. However, traditional methods are time-consuming costly. The objective this study was to determine validate a method quantify attributes using UV-Vis-NIR Spectroscopy as an alternative conventional analyses. work comprised two main phases: (1) creation calibration statistical models derived from spectral data extracted samples...
Traditional method of soil survey is expensive, slow, and must be carried out by experienced researchers. Thus, advances in observation technologies the need to obtain information quickly modern techniques have intensified use proximal sensing. This study characterized surface reflectance spectra (A horizon) related them traditional classification, based on morphological, physical, chemical properties representative pedogenetic profiles, developed two toposequences Distrito Federal, Brazil....
Mangrove revegetation is a vital strategy to recover ecosystem services (e.g., climate regulation and pollutants retention) provided by these ecosystems. Although soils are directly or indirectly responsible for diverse in mangrove ecosystems, few studies have focused on the recovery of soil functions carbon sequestration) after replanting. This study aimed evaluate processes associated with Fe, S, C dynamics its implications restoration functions. Two sites under replanting initiatives were...

Further studies are necessary to cope with variability in mangrove soils. is an effective and fast method for blue carbon stock quantification mangroves. assessment soil organic (SOC) stocks ecosystems essential coastal management activities seeking mitigation CO 2 emissions. However, wet chemical analysis conventionally used quantify SOC may overestimate content due oxidation reduced compounds. This...
Abstract. Seagrass meadows are among the most valuable ecosystems on Earth. However, in tropical countries, there is a substantial knowledge gap “seagrass science”. To address this gap, seagrass soils from three Brazilian coastal regions were investigated (the northeastern, southeastern, and southern coasts). Soil profiles different geological bioclimatic settings sampled, described, analyzed. Thus, detailed macromorphological descriptions, soil classification, physicochemical analysis (soil...
Abstract The use of bulldozers and straight blades for clearing subtropical forests in eastern Bolivia is believed to result serious soil degradation low crop yields. It was hypothesized that chain felling with a tree pusher rake windrowing would cause less give higher An experiment established on Typic Haplustalf compared the effects subsequent yields (i) conventional bulldozer blade (land control), (ii) pusher, windrowing, (iii) (iv) (v) undisturbed forest (control). All four methods...
Unstable soil aggregates can easily be dispersed when mechanical energy is applied, denominated as readily dispersible clay (RDC) which usually measured by turbidimetry. Faster methods that require minimum preparation at reduced costs are needed, such the spectroscopy technique. Nevertheless, technique has not yet been tested on soils. Electromagnetic radiation strong interaction with physical elements (sand, silt, and clay) selective of fraction, mineralogy. Thus, this study assessed...
Abstract. Seagrass meadows are among the most valuable ecosystems on Earth. However, in tropical countries, there is a substantial knowledge gap “seagrass science”. To address this gap, seagrass soils from three Brazilian coastal regions were investigated (the NE, SE, and S coasts). Soil profiles different geological bioclimatic settings sampled, described, analyzed. Detailed macromorphological descriptions, soil classification, physicochemical analysis (soil particle size, pH, pHoxidation,...
A major concern in the study of human behavior is related to machines on which consciousness works for analysis, we addressed phenomenological approach through self, based biological processes perception. This paper aims develop a system recognizing threshold conscious perception, by using visual masking techniques, with variations length presentation target ranging from 17, 33, 50, 67 and 83ms, identifying effect spectrum EEG signal surface processing evoked potentials whit FFT...
