The vermicompost began to expand around the world in the 70's, and it was studied by the scientific community. The objective of this work was to evaluate the reproduction and development of African giant earthworms on different substrates with manure of non-ruminant animals, common grass (Urochloa mosambicensis) and ear of jaguar. To evaluate the different substrates of non -ruminant animals with African giant worms (Eudrilus eugeniae). The work was carried out at the Federal Rural University of Pernambuco (UFRPE) -Academic Unit of Serra Talhada (UAST) -PE, being divided into two stages, in the first the substrates were produced and in the second the vermicompost was produced. After the end of the 35-day vermicompost, the counting of the worms, washing and weighing were carried out, where they had the in-natura weight of each repetition of the treatments, after being added in identified bags and taken to the final drying oven, at the end removed the bag and weighed again getting the dry weight. The variance analysis was performed for thefollowing variables: N, Ca, Mg, P, K, Zn, Cu, B, Fe, Mn, CTC, pH, and weight of adult worms. African giant earthworms showed better development on the substrate with rabbit manure.The vermicompost presented the best chemical composition and higher levels of macro and micronutrients with rabbit manure substrate.
Vermicompostagem como tecnologia aplicada no tratamento de resíduos da agroindústria de polpas de frutas tropicas: uma breve revisão

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.
