    (Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-04-11) Jesus, César Marcelino de; Leitão, Ana Laura Oliveira de Sá; Leitão, Ana Laura Oliveira de Sá; Santos, Taciana do Nascimento; Santos, Wellinghton
    Green manure has aroused the interest of farmers, as it has been standing out as a strategy for sustainable agriculture, since it allows the recovery and maintenance of soil productivity and reduces the cost of using large amounts of chemical fertilizers. This practice consists of improving the physical, chemical and/or biological characteristics of the soil, it functions by replenishing nutrients, such as nitrogen, which is the main nutritive element and is supplied from legumes, in addition to supplying organic matter to the area being applied. Thus, this study aims to present, in the form of a literature review, the benefits of applying green manure in sugarcane cultivation. For this, the context about the importance of sugarcane for its industry was made, as well the definition of green manure and its effects on soil characteristics, beside highlighting some of the most used species for nutrition and atmospheric nitrogen fixation. Therefore, green manure is a vegetative practice that makes it possible to reduce the amount of chemical fertilizers.

    The production of sugarcane has been an agricultural activity that faces several challenges, from those related to environmental issues, including economic ones, among others. This article aims to discuss and analyze the challenges related to environmental and economic aspects faced by sugarcane producers in recent times. The study is contextualized by a methodology that includes theoretical and field research. In the first one, we sought to identify theoretical aspects that deal with the panorama of this agriculture, referring to some points that deserve to be highlighted. In the field research, which is a case study, the vision oftwo sugarcane producers regarding the topic under discussion was evidenced. The methodology, already mentioned as theoretical and field, included the recording and analysis of ideas from theorists who deal with this topic and a questionnaire carried out with the two collaborators, through a Google form. The results obtained with this study were satisfactory, as many aspects of the context related to the panorama of sugarcane in Brazil were perceived, as well as the main challenges highlighted by the two producers regarding economic and environmental issues. The acquired knowledge was important to understand the subject in a deeper way.
