Studies have confirmed the anti-inflammatory activity of extracts of this plant, which can be attributed to the presence of lactones. Its use in Brazil has traditionally been substituted by the species Solidago chilensis, which demonstrates similar therapeutic activity but is more adapted to a tropical climate. It is known that S. chilensis can be used as a substitute for A. montana as they both contain similar active compounds. We acquired eight different commercial brands of “arnica” sold in Rio de Janeiro State, Brazil, in 2013. The analyses of these products were divided into four categories: labeling, macroscopic, microscopic, and microchemical analysis. Labeling analysis followed RDCs (“Resolução de Diretoria Colegiada”) standards (10/2010 through 26/2014). The morphological analyses were performed using microscopic techniques and were followed by microchemical analyses. Our results indicated that none of the samples were in complete conformity with labeling standards, the material was poorly conserved, contaminants were abundantly present, the species were incorrectly identified, and the directions of use were inadequate and potentially dangerous to human health.","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":"48517253","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 experimental design was completely randomized blocks, in factorial scheme 3 x 5, with 3 replications. The first factorwas three side-dress fertilization: witness (without fertilizer); fertilization with 250 kg ha-1 of urea and fertilization with 250 kg ha-1 of urea in the presence of urease inhibitor (UREMAX®) NBPT. The second factor was five single-crosses: 2B433, DKB255, DKB335, NS45, and SYN522. Vegetative development and yield characteristics were evaluated. The Nitrogen sources did not affect the plant height, stem diameter, and foliar area index, only the chlorophyll content in the leaves. For the yield components, there is an effect of fertilization on the number of grain rows and grain yield. The singlecrosses differ among them in vegetative development and yield characteristics. The Nitrogen in sidedress, in the conditions of this study, using the urea with urease inhibitor, increased the fertilization efficiency and raised the grain yield. The single-crosses DKB 255, 2B433, and SYN 522, with the treatment based on UREMAX®, reached the highest yield.","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":"47349387","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 procedures were performed in the ArcGIS® computer program. First, the study defined the limits of the subbasin, and then obtained the features of land use and occupation for the state of Espirito Santo from two mappings, from 2007 to 2008, and from 2012 to 2015. These features were edited, defining the classes of use and occupation only for the subbasin. They were identified, quantified, and mapped. There is a predominance of pasture, with percentages above 50 %, although this occupation decreased by 1.94 % between the periods studied. Coffee growing, the third predominant class, also decreased, which can be attributed to the preference for other activities, such as eucalyptus forestry. This showed strong growth, although with even lower percentages. Mishandling of those areas can cause environmental and economic damage. However, the areas of native vegetation represented a minimal rate, even with an increase, due to the decrease of vegetation in the early stage of regeneration. Macega (wild vegetation) coverage, besides being close to the native vegetation and which was predominantly fragmented, indicates problems with the use and occupation planning. The action of the local riverbasin committee and public managers, besides environmental education, and correct management of rural activities, are necessary actions.","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":"42775491","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}

Considering the control group, the use of different dosages of nanofertilizers resulted in a significant increase in the bioelements and pH contents. Besides effects of area and time of planting, their two and three effects on tuber chlorophyll contents were reported significant. The highest protein and nitrogen portion of the potato tubers were related to spraying solution of Mg (1.0 %) + Fe (2.0 %) nanofertilizers. Increasing nanofertilizers supplementation reduced the nitrate content of potato tubers. The results indicated that the application of nanofertilizers significantly increased the carotenoid portion of the potato tubers. The interaction effects of nanofertilizers and planting data on chlorophyll index and calcium levels of potato tubers were completely significant.

This allows this system to integrate with other activities such as the dairy industry, taking advantage of the milk by-product, reducing the environmental liability for disposal in the environment. Therefore, the objective was to evaluate the growth and productivity of rice grains under different doses of acid milk serum (0 m3 ha-1, 5 m3 ha-1, 10 m3 ha-1, 20 m3 ha-1, 50 m3 ha-1, 100 m3 ha-1, and 150 m3 ha-1), in soil applications with monitoring of fertility and electrical conductivity levels. The rice was sown in the UFLA experimental field, using the BRSMG Esmeralda lineage. Seven different doses were used, divided into two applications via soil. No cover fertilization was carried out. Yield and crop growth variables were determined by monitoring the nutrient content in the soil profile and the sodification and salinization capacity of the residue. It was found that the increase in serum doses increased the electrical conductivity and the percentage of exchangeable sodium by 1.75 and 7.75 compared to the control, but did not cause the process of sodification and salinization of the soil. As acid milk serum is a significant source of potassium, its use in the soil did not promote significant grain yield. It was concluded that the acid milk serum in the doses used did not cause sodification or salinization of the soil. This residue is the safe dose that can be used as potassium and nitrogen. The acid milk serum in the tested conditions did not increase the growth of the culture.","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":"46130580","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}
