Thus, knowing the characteristics of the environmental planning units can contribute to minimizing damage and planning conservationist actions. The morphometric characteristics of the Córrego do Perdido river basin were determined for environmental planning purposes. To this end, we used radar data from the Shuttle Radar Topography Mission (SRTM) to represent the Digital Elevation Model (DEM) and geoprocessing techniques in a Geographic Information System (GIS) environment. To elucidate the hydrological behavior of the basin, we estimated some morphometric parameters. The drainage area obtained corresponds to 31.11 km², and the perimeter measures 33.57 km. With an irregular shape, the basin presented a shape factor equal to 0.12, compactness coefficient of 1.69, circularity index of 0.347 and small flow extension (0.1052 km). The drainage density found was 2.38 km-2, indicating high drainage capacity. The basin had a strong wavy terrain (47.38% of the total basin area), with an average slope of 30.6% and an average altitude of 1,145 meters. The physiographic characterization revealed through the morphometric indices that the basin has an elongated shape and a dendritic drainage network of fourth order and, disregarding the adverse hydrological events, is not very susceptible to flooding. The high drainage capacity contributes to the infiltration of water into the soil, and the vegetation cover of the slopes must be preserved.","PeriodicalId":43096,"journal":{"name":"Revista Agrogeoambiental","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2022-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48512438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Brazil, this condition is studied substantially in medium to very clayey textured soils, whose adsorption activity is expressive. The aim of this study was to evaluate the maximum phosphorus adsorption capacity (CMAP) in sandy-textured soils with fertility built in the Cerrado biome. Areas with representative soils were selected in the cities Luís Eduardo Magalhães (LEM / BA) and Guaraí (TO), with the following vegetation cover: a) LEM: natural vegetation and cotton; b) Guaraí: natural vegetation and soybean. Soil samples were collected in the 0-20 cm and 60-80 cm layers, in which chemical and physical analyzes were performed periodically, as well as analyzes related to phosphorus adsorption such as Prem and CMAP and PESN. Prem contents are higher in the 0-20 cm layer for the LEM region. The CMAP is not very expressive in the soils of the two studied regions, with the Guaraí soils having higher relative adsorption potential due to the higher values of the CMAP/clay ratio.","PeriodicalId":43096,"journal":{"name":"Revista Agrogeoambiental","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2022-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44182926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed scale of grades is based on a 5-percentage point scale (5-PPS), i.e., the weed control grade 1 is 0% to 4%, grade 2 is 5% to 9%, and so on up to 20 (95% to 99%) and 21 (100% weed control). This scale was based on three factors. The first considers the decreases in the coefficient of variation and standard deviation in statistical analyses, which improve the precision of results, when compared to a 20-percentage point scale (20-PPS), and the detection of significant differences between means that are not detected in the 20-PPS. The second factor is based on the comparison of the described symptomatologic analysis that attributes 5 grades that are, analogically, a 20-PPS. The proposed scale improves the statistical and agronomical evaluations. Therefore, the proposed methodology is better in differentiating results of weed control efficiency in field evaluations. The third factor considers improvements in the interpretation of results of herbicide efficiency, enabling the use of higher grades in the scale for studies on resistance to herbicides by indicating the selection pressure. It is concluded that the use of the proposed grading scale reduces the coefficient of variation and results in a better interpretation of the technical reality of the effects of herbicides.","PeriodicalId":43096,"journal":{"name":"Revista Agrogeoambiental","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2022-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42157839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Teas are an accessible source of antioxidant compounds, especially polyphenols that impart flavor, aroma and pharmacological properties. Considering the context of using natural products for health maintenance, the present study aimed to analyze the content of total phenolic compounds, antibacterial and antioxidant activities of infusions using Morus nigra, Casearia sylvestris, Hibiscus sabdariff and Moringa oleifera commercialized in Muzambinho/MG. The infusions were prepared by adding 100 mL of distilled water at approximately 100oC over 1 g of herb at room temperature for 10 minutes. The analysis of total phenolic compounds was performed using Folin-Ciocalteau. For the analysis of antioxidant activity, the free radical DPPH was used and the results were expressed as a percentage of scavenging activity. For the analysis of antibacterial activity, the microdilution in broth assay was performed in order to find the minimum inhibitory concentrations. It was possible to conclude that the infusion with the highest levels of phenolic compounds were C. sylvestris and M. oleifera, while those that showed a greater antioxidant activity were M. oleifera and M. nigra. As for antibacterial activity, all infusions were able to inhibit E. coli, especially the infusion of C. sylvestris, which was also able to inhibit S. aureus. Although all of the herbs showed antioxidant and antibacterial activities, and also phenolic compounds, C. sylvestis was the herb that stood out in this work because of its phenolic composition and antibacterial activity. In sum, it is concluded that future work is needed to elucidate the exact chemical composition of the infusions and other biological activities.","PeriodicalId":43096,"journal":{"name":"Revista Agrogeoambiental","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2022-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45456925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reclassified thematic maps of soil slope and vulnerability to water erosion were combined to create the soil susceptibility map to water erosion, which, in turn, was combined with the thematic maps of soil use and rain erosivity. The result was then reclassified, giving rise to the potential environmental fragility map. In the places identified with high potential environmental fragility, information was collected by observing the aspects of the physical, biotic, and anthropogenic environmental components of the landscape. Areas with high potential environmental fragility in the Federal District were found. In those locations, the uses and occupations of the soil observed were intensive farming, small rural activities, managed intensive livestock and degraded intensive livestock. Land use and occupation in areas with high potential environmental fragility of the Federal District, with “degraded intensive livestock”, make such sites environmentally fragile since there is a scarcity of non-preserved natural areas and there is no soil conservation method. It was concluded that, for the use and occupation of the soil with high potential environmental fragility areas in the Federal District, which are taken by intensive farming, small rural activities, and managed intensive livestock, the conservation of the natural areas and the vegetative and mechanical soil conservation techniques must be implemented.","PeriodicalId":43096,"journal":{"name":"Revista Agrogeoambiental","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2022-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46727088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work aimed to verify, through the species composition, if there is natural regeneration of the clearing with and without management and if it is possible that the clearing regeneration occurs without the management. The study site covered a clearing and a fragment of the Atlantic Forest Biome, in the municipality of São Sebastião/SP, north coast of the state of São Paulo. Ten subplots of 0.5 m x 1.0 m were installed randomly in 8 transects of 2.0 m x 50.0 m, with and without seedling management, where the set of seedlings with up to 20 cm was sampled. At the end of the study, 266 individuals were found, grouped into 38 families and 5 life forms (arboreal, shrub, herbaceous, epiphyte and liana), later classified into: 45 species (60.81%), 23 genera (31.08%) and 6 families (8.10%). Myrtaceae and Rubiaceae stood out as the most species-rich families, with 8 and 6 species, respectively. In the clearing, 22.2% of the sampled species were found, while 77.8% belonged to the forest. The difference between the number of species in the clearing and in the forest fragment suggests that the invasive species Melinis minutiflora and Scleria plusiophylla can hinder the establishment of seeds, preventing the germination of native species. Therefore, for the clearing regeneration process to occur faster, human intervention is necessary in the management of invasive species. Accordingly, the elaboration of a revegetation project withmonitoring and evaluation of the area of study was emphasized.","PeriodicalId":43096,"journal":{"name":"Revista Agrogeoambiental","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2022-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47097426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiment was carried out in a greenhouse in São Benedito farm, located in São Benedito, Ceará. The varieties studied were Lisianthus ABC 2-3 Blue, Lisianthus Allemade White and Lisianthus ABC 2-3 Rose, and three environments, one with aluminized screen (AS), one with red screen (RS) and the third environment without screen shading (WS). The experimental design was completely randomized in a 3 x 3 factorial scheme, with three environments and three varieties with three replications. The following were analyzed in cm: button diameter (BD); rod height (RH); actual size (AS); commercial size (CS); rod thickness (RT); and by counting, the number of buttons per stem (BS). The blue variety was better adapted to the conditions imposed by the AS environment, the rose variety presented the best results in the WS environment and the white variety, under the conditions of the experiment, would be unsuitable for the crop cultivation. The RS environment does not offer conditions conducive to satisfactory growth in rod size.
