Item Agregados do solo e índices de agregação em áreas de vegetação nativa, agricultura e pastagem no semiárido de Alagoas(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-06-06) Silva, Ayanna Araujo; Maia, Stoecio Malta Ferreira; http://lattes.cnpq.br/6110419050119583; Calheiros, Altanys Silva; http://lattes.cnpq.br/9353777923030637; Medeiros, Aldair de Souza; http://lattes.cnpq.br/7861355880079380The expansion of agricultural activities with conventional management in the semi-arid region of Brazil, associated with the intrinsic characteristics of the soil in this region, can directly or indirectly influence soil aggregation and, consequently, the storage of soil organic carbon (COS). Thus, the objective of this work was to evaluate the impacts promoted by conventional land use systems (agriculture and pasture) on the stability of aggregates of different types of soils in the municipalities of Traipu and Santana do Ipanema, located in the semi-arid region of the state. From Alagoas. Soil samples were collected in the municipalities of Traipu and Santana do Ipanema. In total, four areas were sampled. In each of the areas, samples were collected in three trenches (replications) at different depths. The stability analysis of aggregates in water was performed using Yoder's agitator equipment, and later, the soil aggregation indices were calculated: weighted average diameter, geometric average diameter, stability index and instability index. The results obtained were submitted to analysis of variance (ANOVA) using the F test. Differences between the means were tested using the Tukey test (p<0.05). The results showed that the pasture system with less time (4 years) presented smaller amounts of macroaggregates (diameter >2.00 mm), and greater distribution of mesoaggregates (diameter of 2.00 and 0.25 mm) and microaggregates (diameter < 0.25 mm) compared to native forest and other pastures. The IS values revealed that the agricultural system with 47 presents physical conditions of the soil closer to its natural form in the deeper layers of the soil.Item Análise do potencial efeito do extrato de urtiga no diâmetro e na altura da planta de milho no Município de Marechal Deodoro, AL(INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2025-04-16) Costa, Maisa de Araujo; Bastos, Adelmo Lima; https://orcid.org/0000-0001-6186-8856; http://lattes.cnpq.br/6125212623471598; Madalena, José Antonio da Silva; https://orcid.org/0009-0002-7289-7817; http://lattes.cnpq.br/1301228115317438; Gama, José Aparecido da Silva; https://orcid.org/0000-0002-9082-6564; http://lattes.cnpq.br/7413041757828843; Santos, Anselmo Lúcio Aroucha; http://lattes.cnpq.br/8873799404904994; Farias, Vera Nubia Carvalho de; https://orcid.org/0000-0001-6223-0942; http://lattes.cnpq.br/3867201737324584Nettle is a plant found in various regions of the world, including Brazil, where it can be found in abundance in the backlands of Alagoas. Some pharmaceutical industries use its extract in the production of drugs, thanks to its rich variety of substances. The objective of this study was to use nettle extract as a potential nutritive agent, capable of stimulating the growth of corn crops. The methodology used was, initially, planting plots of corn, which were sprayed for 75 days; then the aerial part was evaluated by measuring diameter and height, using a caliper. It was found that in the evaluation of plant diameter, in the period of 15 days, the best doses were between 200 and 800 g, and on the other days, the best dose was 200 g. For the height variable, in the 15-day period the best dose was 600 g, but it did not differ statistically from the results presented at 30 days, where the best doses presented were 200 to 600 g. In relation to 45, 60 and 75 days the best dose was 200 g of nettle. Thus, it is concluded that using nettle extract from the 200 g dose onwards caused a reduction, decrease in the diameter and aerial part of the plant.Item Estudo de caso: mapeamento dos fragmentos de Mata Atlântica na fazenda Bento Moreira em Boca da Mata - Alagoas(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-07-07) Lima, Alan Douglas Fernandes de; Silva, Pedro Guilherme Fernandes da; http://lattes.cnpq.br/3844758515992699; Bastos, Adelmo Lima; http://lattes.cnpq.br/6125212623471598; Souza, Felipe Carvalho Olegário de; http://lattes.cnpq.br/0755590702540629The Atlantic Forest Biome, according to the SOS Mata atlântica foundation, is largely degraded in Brazil, so it was necessary to apply this work in order to preserve and conserve this biome so rich in biodiversity. The theme of this work is: Case study: mapping of the Atlantic Forest fragments in the Bento Moreira farm - Boca da Mata - Alagoas. And as specific objectives, identify which areas are in balance (climax), Check for degradation in forest fragments and point out which are more degraded, detect which forest area has greater biodiversity and finally Implement good environmental practices on the farm. In order to put into practice, the objectives of this work, some technical visits were made to the study site to collect data and gather information about the Atlantic Forest fragments. Then, it was found that all forest fragments on the farm are in good condition. Finally, good environmental practices were put into practice on the farm to further conserve the natural resources of the location, since the farm carries out some economic activities that generate environmental impacts if carried out incorrectly.Item Implantação de um sistema de captação de águas pluviais para fins não-potáveis na escola municipal Rui Palmeira em São Miguel dos Campos – Al(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2021-05-25) Correia, Jefferson Kleyton dos Santos; Fiori, Ana Paula Santos de Melo; http://lattes.cnpq.br/2598153346850335; Machado, Bruna Maria Ferrari; http://lattes.cnpq.br/3612552671884286; Gama, José Aparecido da Silva; http://lattes.cnpq.br/7413041757828843The topic in question brings a project to implement a system for capturing and using rainwater, addressing two considerable factors, approaching the importance of preserving natural resources, in particular fresh and potable water and the importance of using rainwater for non-potable purposes, however this water has a low storage cost, making it useful for different functions, such as gardening, discharging and washing yards and vehicles. Therefore, the purpose of this study is to demonstrate the importance of water resources and the preservation of sources and streams, on which the beings of the terrestrial globe depend for their subsistence, informing about their distribution and capture in the world and in Brazil, and to present the main advantages of reusing rainwater for non-potable purposes, through a collection system implemented at the Rui Palmeira Municipal School - São Miguel dos Campos, in addition to serving as a basis for the creation of new systems.Item Programa merenda da terra em Marechal Deodoro – AL : perfil dos agricultores cadastrados(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2023-12-14) Fernandes, Gilmara Pereira; Lucena, Rodrigo de Melo; http://lattes.cnpq.br/6095168056343998; Bastos, Adelmo Lima; http://lattes.cnpq.br/6125212623471598; Santos, Geraldo Luiz Valle dos; http://lattes.cnpq.br/5316292387419022This research to conclude the Environmental Management course has as its methodology the study of an exploratory and investigative nature, where data were collected through a semi-structured questionnaire with the aim of analyzing the profile of farmers registered in the Merenda da Terra da Program. city of Marechal Deodoro in the state of Alagoas. A bibliographic review study was also used to better understand and analyze what was collected. The description of the context where farmers produce and sell enabled recommendations for the difficulties and limitations identified in the program. Therefore, there were 35 farmers interviewed from 37 active farmers, out of a total of 67 registered. Challenges to be addressed in the program were identified as an incentive to improve and increase production, requiring investments for this to occur; the lack of interest among young people in these families in current production and the continuity of agriculture in the family; the need for these families to organize themselves into associations or cooperatives, possibly gaining greater unity and robustness, thus assisting in the production/cultivation, sale and distribution processes; and implementation of the SAF’s Agroforestry System as a possible efficiency for recovering soil nutrients for the benefit of agricultural cultivation.Item Viveiro de plantas nativas: laboratório de vivências práticas em educação ambiental(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2023-06-15) Omena, Ana Paula da Silva Feijó; Dias, Sheyla Karine Barbosa de Macêdo; http://lattes.cnpq.br/2777322313238567; Santos, Maria do Socorro Ferreira dos; Gama, José Aparecido da Silva; http://lattes.cnpq.br/7413041757828843The Caatinga biome predominates in much of the northeast region of Brazil, comprising about 48% of the state of Alagoas, extending across several municipalities, including the municipality of São José da Tapera. The Caatinga has been suffering suppression processes that have put the diversity of forest and animal species in this biome at risk. Therefore, it is necessary to create alternatives to minimize the effects of human and natural actions. The native plant nursery can be assumed as an alternative to minimize such effects, in addition to serving as a laboratory for studies in the area. From this idea, the present work aimed to build a nursery of native plants in a participatory way, involving the residents of the Caboclo village community, located in the municipality of São José da Tapera, located in the backlands of the State of Alagoas. The methodology used in this study used a qualitative and quantitative approach, associated with an action research, as it is a participatory investigation. The study was subdivided into 6 stages, namely the presentation of the project, the beginning of conversation circles on fauna and flora themes, visiting existing nurseries, obtaining seeds, setting up the nursery and planting seedlings. The study sample included 54 students who attend the only public school in the village and were selected with the support of the school coordination. At the end of the stages, it became evident that the nurseries can be used as environmental education strategies, as they help to preserve the entire web and life cycles of a biome.
