The location and venue of a supervised internship (ESO) was located in the city of Taquaritinga do Norte, Pe, Brazil on the Farm Varzea da Onca under the sponsorship of Yaguara Ecológico/Augusta Internacional. The intern, Eduardo Gonçalves de Oliveira, a member of the Xukuru indigenous community, worked on the farm during the months of August and September 2019. The farm is located within the Borborema regional mountain range, where altitudes range from 700 to 1000 meters above sea level. The terroir is characterized by a remnants of a native forest called the Mata Atlântica, wherein since 1750 small family farms have cultivated coffee within a policulture of biodiversity. The farm, Varzea da Onca, has aggregated over 30 parcels of traditional small family holdings into a single hydraulic micro basin. This land pattern guarantees that there is an ecological conservation and protection zone to pursue the farming practice called “Ecoagriculture” wherein the biological systems of nature are valued, preserved, and predominate in the daily work routine. The internship focused on the value chain of coffee production, processing, and marketing of the specialty coffee brand “Yaguara Ecológico”. This practical experience included a range of activities from seed selection, planting, germination, pruning, harvesting, processing, and roasting. In addition, the principles and practices of Ecological Agriculture were discussed and examined on a daily basis, so that the theoretical and conceptual foundations of practical options were understood. The farm as an biological ecosystem whose purposes and practices focus on sustainable development was the the primary takeaway of the internship.

(2019-12-11) Maia, Hermógenes Bezerra; Nunes, Ramom Rachide; http://lattes.cnpq.br/6182302726895126; http://lattes.cnpq.br/1881302618582553
The low natural fertility of Brazilian soils is due, in the most part, to their high acidity and nutrient levels below those needed for cropproduction. This problem is more accentuated in the interior of the Brazilian Northeast, due to its edaphoclimatic conditions, characterized by their dry climate and irregular rainfall pattern. In another context, fish farming is becoming moreprominent and growing in the region, as aquaculture demands less water than conventional livestock, with an average of 800 L of water per kg of fish produced. Even in its importance, fish farming is considered an activity that generatespotentially toxic effluents, because it has a high content of organic matter (OM) and nutrients. Taking both issues as a challenge — the problem of poor soil fertility and effluent generation by aquaculture — the implementation of an integrated agriculture-fish farming system would be an interesting alternative as it would aim at reusing water from fish farms through enhancement of OM and nutrient recycling through irrigation, promoting benefits for crop production and agrarian development. Part of these benefits is imputed to the hormone-like activity, attributed to the presence of organic molecules that make up the OM fractions. In this sense, the present work aimed to conduct a chemical study of water from fish ponds for use in irrigation of plants of economic interest, besides evaluating the hormone-like activity of OM present in the analyzed samples. Fish farming water samples (FFW) were collected from the Cooperativa dos Produtores do Vale do Itaparica (COOPVALE), in the municipality of Itacuruba (PE) and their characteristics (pH, EC, turbidity, nutrients and TOC) were determined. To evaluate hormone-like activity, bioassays were performed with cucumber (Cucumis sativus) seeds, with different carbon concentrations, present in the FFW. According to the results obtained in the characterization of pisciculture water, it is considered that its chemical characteristics allow the use in irrigation ofplants of economic interest. In the bioassays it waspossible to observe the biostimulant action of FFW at concentrations from 5.0 mg C L-1. Furthermore, it is considered that the higher the carbon concentration in the FFW sample, the greater the biological response, as observed in the increase of C. sativus root growth index. Thus, it is concluded that it is possible to recycle and reuse the OM and nutrients of fish water in cropproduction,in favor of agrarian development within the NE Region, in an integrated system, agriculture-fish farming, in an organic farming system. agroecological, mimicking a cultivation in a family nucleus system, in the interior of the Northeast, in the Pernambuco hinterland.

The constant search of people for a healthier life has put in evidence the organic agriculture that consists of a balanced way of production, which dispenses the use of substances harmful to the human health and the maintenance of the natural ecosystems. This has meant that the interest of farmers in entering this niche market is increasing, especially by those who belong to the class of small family farmers, who are attracted by the possibility of acquiring a better quality of life through of this system of production, which also constitutes a good alternative for income composition. In the light of this, this work sought, through field research, to identify the main characteristics of the producers of Triunfo -PE, in order to obtain data that allowed to draw the profile of the current situation experienced by them in the production and commercialization of their products. Where, through the obtained results, it was possible to verify the relevance that the gains derived from organic activities play in the income composition of the families, occupying the second place in degree of importance with respect to the income of the family nucleus.

(2025-03-21) Silva, Mikaely Cássia da; Evangelista Júnior, Walter Santos; http://lattes.cnpq.br/6728342264331935; http://lattes.cnpq.br/8343521710997865
O presente trabalho teve como objetivo fortalecer a fiscalização e o controle do uso de agrotóxicos na Região Metropolitana do Recife, garantindo a segurança alimentar e a conformidade com as normas ambientais. O estudo foi conduzido no âmbito do Estágio Supervisionado Obrigatório (ESO), abrangendo atividades internas e externas relacionadas ao monitoramento de resíduos de agrotóxicos em produtos agrícolas comercializados em feiras orgânicas e à rastreabilidade dos produtores. As atividades internas incluíram a análise de legislações e acordos institucionais, revisão bibliográfica, seleção de produtores com resultados insatisfatórios em fiscalizações anteriores e a elaboração de um questionário para aplicação em campo. A escolha dos produtores baseou-se na identificação de resíduos de agrotóxicos acima dos limites permitidos, na localização das feiras e na viabilidade logística das visitas. As atividades externas envolveram fiscalizações presenciais nas feiras, entrevistas com os produtores e visitas às propriedades rurais para verificar a rastreabilidade dos produtos e a conformidade das práticas agrícolas. Durante essas inspeções, foi constatada a persistência de irregularidades no uso de agrotóxicos por alguns produtores, indicando desafios na fiscalização e na adesão às normas vigentes. Além disso, a participação em reuniões do Grupo Condutor da Vigilância em Saúde de Populações Expostas a Agrotóxicos (GC-VSPEA) possibilitou a troca de conhecimentos e a formulação de estratégias para aprimorar a fiscalização e a conscientização sobre os impactos dos agrotóxicos na saúde pública e no meio ambiente. Os resultados evidenciaram a necessidade de um monitoramento mais rigoroso e contínuo, bem como do fortalecimento de ações educativas junto aos produtores. Conclui-se que a fiscalização, aliada a um trabalho de conscientização e ao uso de ferramentas de rastreabilidade, pode contribuir significativamente para a redução do uso inadequado de agrotóxicos, promovendo uma produção agrícola mais segura e sustentável.
Vermicompostagem como tecnologia aplicada à valorização da matéria orgânica de resíduos do milho, nas condições edafoclimáticas do sertão pernambucano
(2019-12-11) Siqueira, Andreza Jayane Nunes de; Nunes, Ramom Rachide; http://lattes.cnpq.br/6182302726895126; http://lattes.cnpq.br/5272674335190028
This research presents the vermicomposting as an environmental technology applied in the recycling and treatment of waste obtained in the maize production, taking into consideration the edaphoclimatic conditions of the Pernambuco Backwoods, under the perspective of the Environmental Chemistry. In addition, a physical and chemical study of vermicomposting were carried out. Vermicomposting is a process of biological transformation, as well as bio-oxidation and stabilization of organic matter (OM), turning it into a fertilizer of high agricultural potential. In this study, the vermicomposts were produced adding residues of corn, straw and cob, also adding goat manure and sawdust as organic substrate. In each vermicompostor 250 Eisenia fetida earthworms. were added. During the 120 days of the experiment, the following chemical attributes were analyzed: total solids (TS), pH, total organic carbon (TOC), organic matter (OM) and cation exchange capacity (CEC). The pH, TOC and OM results showed a decrease in their values during the vermicomposting process; while the CTC content increased. Both trends indicated that vermicomposts reached stability and maturity desired. In addition, worms showed good adaptation to vermicompostors. Thus, it was concluded that vermicomposting can be used as an effective technology for corn waste treatment and production of agricultural inputs. In the future, it is expected to apply the composed of new corn crops, renewing the cycle of the production chain, under conditions of cycling its organic matter and nutrients in favor of the agrarian and social development of the interior of the Brazilian Northeast.
Vermicompostagem como tecnologia aplicada no tratamento de resíduos da agroindústria de polpas de frutas tropicas: uma breve revisão
(2024-03-01) Silva, Almir Mendes da; Nunes, Ramom Rachide; http://lattes.cnpq.br/6182302726895126; http://lattes.cnpq.br/0859445695330939
Vermicomposting is an environmental technology applied to the treatment of organic waste, converting it into an agricultural input with high agronomic potential, produced from the combined action of earthworms and the microorganisms that live in their digestive tracts. In this process, earthworms feed on organic waste and excrete a material called vermicompost, rich in nutrients and microorganisms beneficial to the soil-plant system. The chemical attributes of vermicompost improve soil structure, increase its water retention capacity and promote microbial activity. This environmental technology has several advantages, as it is an efficient and sustainable way of recycling organic matter and nutrients, as well as mitigating the environmental impacts caused by waste that ends up in landfills or is abandoned in the field. Among the waste that is a cause for environmental concern, specifically tropical fruits: yellow mombin, Guarani cherry, and Brazilian cherry (main Brazilian native tropical fruits). Furthermore, by-products from fruit processing are not reused due to their lack of commercial value and can cause several environmental problems when disposed of inappropriately. Thus, this work aimed to carry out a bibliographical review on the originality of the project, as well as the possibility of vermicomposting the by-products of fruit pulp processing, comparing this study with others found in the literature. As a result, no studies were found in which yellow mombin, Guarani cherry, and Brazilian cherry waste are vermicomposted, giving originality to the proposal. Furthermore, studies with similar fruits, reported in the literature, indicate the possibility of vermicomposting the aforementioned residues, producing an input with high agronomic potential, suitable for use in organic and ecologically based agricultural systems.
Vermicompostagem de resíduos de milho nas condições culturais e edafoclimáticas do sertão brasileiro
(2022-12-14) Silva, Jefferson Campos da; Nunes, Ramom Rachide; http://lattes.cnpq.br/6182302726895126; http://lattes.cnpq.br/6584309908538134
A vermicompostagem tem sido reportada como uma importante tecnologia para reciclar matéria orgânica e nutrientes de resíduos agrícolas. No entanto, as condições edafoclimáticas são obstáculos no semiárido, pois as altas temperaturas e a baixa umidade podem interferir negativamente na adaptação das minhocas e na produção de vermicomposto. Assim, neste estudo, a vermicompostagem foi aplicada no tratamento de resíduos de milho (sabugo e palha), sob condições culturais (utilizando resíduos locais e condições de campo replicáveis) e edafoclimáticas do sertão brasileiro. Durante 120 dias foi realizado um monitoramento químico. Os resultados mostraram um aumento na estabilidade da matéria orgânica (MO), além de um aumento considerável no potencial agrícola do vermicomposto: a CTC aumentou de ~37 para 649 cmolc kg-1 ; MO e TOC reduziram de ~83 para 49% e ~43 para 27%, respectivamente. Por fim, os vermicompostos produzidos são considerados adequados para melhorar a qualidade do solo e promover uma agricultura moderna, aumentando a produtividade e a geração de renda no campo.
