Groundwater monitoring programs are tools to subsidize the decision-making in this sense. In Ceará state, the monitoring of Araripe sedimentary basin aquifers is important for the development of the region. In this scenario, the present work aimed to study the groundwater level through an exploratory analysis of time series. The study area covered the eastern portion of the Araripe sedimentary basin, in the municipality of Milagres, in Ceará state. As the object of this study, it was obtained the time series of monthly average groundwater levels in a monitoring well of RIMAS/CPRM and installed in the Middle Aquifer System. Graphical and numerical methods were applied for the identification and description of time series main characteristics. Precipitation data in the study area were used to evaluate the system recharge. Results were discussed according to the environmental aspects of the study area. As a result, it was possible the identification and description of time series patterns such as trend and seasonality through the applied methods. It is also highlighted the sharp drawdown of groundwater levels in long term in the time series, reflecting the quantitative state of the aquifer system, as well as the groundwater recharge during the rainy season of the region, evidenced by the study of time series seasonality together with the precipitation data..","PeriodicalId":43096,"journal":{"name":"Revista Agrogeoambiental","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2021-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47635726","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 first step in the proper packaging design of agricultural products, particularly fruit, is to conduct a precise simulation of the truck transport. Thus, this research was conducted to analyze the vibration levels for truck transport using multi-sensor-based computing on packaged fruit in Iran (the first), one of the leading agriculture in Middle East Asia. Towards this goal, a wireless sensor network made of three sensor nodes with tri-axial accelerometers was designed to measure the vibration levels for truck transport at three package locations equipped with leaf-spring suspension in local and highway roads. To measure the vibration data a power spectral density function (PSD) levels were applied. Compared to the International Standards (ASTM 4728: West Conshohocken, USA, ISTA: Chicago, USA), the PSD levels of the truck in both roads types were higher in 1 to 35 Hz, and lower in 35 to 200 Hz. In particular, the differences in directional vibration levels were more pronounced in the low-frequency range of 10 Hz in both road types. The highest amount of truck bed acceleration occurred in the packages located at the rear end of the trucks. And, the peak PSD values were obtained as equal to 0.178 G2/Hz (rear-up), 0.136 G2/Hz (rear-down), and 0.096 G2/Hz (front-up) locations, respectively. Meanwhile, the road quality had affected the vibration levels in such a way that the peak PSD value obtained on highways was lower than that of the ones of the local roads. According to the results, the amount of acceleration on the heavy truck beds on the country’s roads can be considered 0.654 G. In sum, the current results can be used to simulate the truck transport conditions by programmable vibration simulators to reproduce the vibration conditions for package testing in Iran roads. And, the findings are of high interest to improve packaging design, reduce fruit damage, maintain shelf life, smart transportation, and related industries.","PeriodicalId":43096,"journal":{"name":"Revista Agrogeoambiental","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2021-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48159821","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 data was gathered from secondary information of the federal, state, and town public databases, besides face-to-face questionnaires, rapid assessment protocols and high-definition satellite mapping of land use for the last few years. It was possible to assess that conservation actions and Permanent Preservation Areas (APPs) are reduced and that interviewed people present limited knowledge about public policies of family farming stimulation.

Large forests, such as the Atlantic Forest, are important carbon reservoirs removing carbon from the atmosphere and storing it in their biomass. The assessment of carbon stock from forests fragments helps to establish a better understanding of the carbon cycle and the potential of climate mitigation strategies. Thus, we estimated the biomass and carbon stock of an Atlantic Forest fragment located in the foothills of Pedra de Itaocaia. We used a non-destructive methodology based on climbing techniques and an allometric equation. We climbed seven trees in order to thoroughly measure them in whole and calculate the volume of arboreal compartments. We compared the measured volume obtained from the climb to an estimated tree cylindrical volume and established a correction factor of 0.65 between both (i.e. tree form factor). The tree form factor adjusts the allometric equation and allows carbon estimations without the need to climb all trees in the fragment. The biomass and carbon stock estimates obtained were 100.1 and 50.5 MgC/ha, respectively, which implies that the fragment is on an intermediary stage of regeneration at approximately forty years old. This allometric equation efficiently integrates structural features of forest fragments similar to the one of Pedra de Itaocaia, thus contributing to advance the knowledge about processes taking place in forest fragments situated in the Atlantic Forest. Carbon estimation is imperative for a better understanding of climate mitigation strategies that can revert the threat of climate change to ecosystems.","PeriodicalId":43096,"journal":{"name":"Revista Agrogeoambiental","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2021-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44554355","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}

Therefore, the antagonistic potential of Trichoderma sp. should be better studied against other phytopathogens, thus expanding the biofungicide options on the market. The objective of the present work was to evaluate the antagonistic potential of different isolates of Trichoderma against the in vitro mycelial growth of F. oxysporum f. sp. lycopersici. Four isolates of Trichoderma spp. were tested, three collected in litterfall and one commercial isolate (T. asperellum). The Trichoderma spp. isolates were evaluated for antagonistic potential against F. oxysporum f. sp. lycopersici using the culture pairing technique. The variables evaluated were: mean colony size (MCS), mycelial growth inhibition percentage (MGIP), mycelial growth rate index (MGRI) of phytopathogen, and antagonism of isolates of Trichoderma spp. through a scale of grades.

This work aimed to study the spatiality of water precipitation, crop evapotranspiration, and the need for water supplementation in soybean cultivation in the microregions of Jales-SP and Andradina-SP for the summer harvest. The water balance was determined by the Thorthwaite and Mather (1955) method, with data made available by the Agrometeorological Stations Network operated by the Hydraulics and Irrigation area of UNESP Ilha Solteira. We considered an available water capacity (AWC) of 40 mm. The study took place from the simulation of the water condition of a soybean crop sown on November 4, 2020. In the water deficit condition, the actual evapotranspiration (ETa) was considered null at a 20 % deficit, and the other values followed the same mathematical proportion. The mean rainfall of the period, crop evapotranspiration, and water deficit of each weather station were interpolated through ordinary circular kriging in ArcGIS 10.7 software. The water deficit in the soybean crop in the northwest region of São Paulo is related to the poor distribution of precipitation during the cycle and the significant recurrence of Indian summers all through the area. For the producers’ safety, investment in irrigation systems anticipating this poor distribution is justified. The water deficit in the region is variable. In years with good rainfall distribution, it can reach zero values, and in years with poor distribution, it can reach values greater than 180 mm.","PeriodicalId":43096,"journal":{"name":"Revista Agrogeoambiental","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2021-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46389382","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}
