Uso da manipueira na agricultura: uma revisão bibliográfica

Abstract

This undergraduate thesis aims to explore the use of cassava wastewater in agriculture, addressing its various applications as soil fertilizer, foliar fertilizer, and in the control of nematodes, insects, and mites. This study was conducted through a comprehensive and detailed literature review of articles and journals that covered this topic and demonstrated how this by-product derived from cassava has various other uses. This work explains how cassava wastewater is a yellowish liquid by-product resulting from cassava processing, essential for the production of starch and other derived products. Historically considered waste, recent studies have revealed its potential as a valuable resource in sustainable agriculture, distinguished by its richness in essential nutrients and bioactive compounds. Through a detailed literature review, this study examines the nutritional properties of cassava wastewater, its chemical composition, and its effectiveness in improving soil fertility. Cassava wastewater is recognized for containing high levels of potassium, calcium, magnesium, nitrogen, and other essential nutrients crucial for the healthy growth and development of plants. Additionally, it contains important micronutrients that can be crucial for increasing agricultural productivity and crop quality. In the context of integrated pest management, cassava wastewater has shown promising results in controlling nematodes, root parasites responsible for significant economic losses in important crops. Studies have indicated that the application of cassava wastewater to the soil can reduce the population of these nematodes, possibly due to its bioactive compounds that interfere with the life cycle of these organisms. In addition to nematode control, cassava wastewater also has potential in managing insects and mites that negatively affect agricultural crops. Through critical analysis of scientific studies and empirical data, this undergraduate thesis seeks not only to expand knowledge about the potential of cassava wastewater but also to provide practical information for farmers and researchers interested in promoting more efficient and environmentally responsible agricultural practices. This research aims to significantly contribute to the development of agricultural strategies that value available natural resources, promoting food security and environmental sustainability in agricultural communities. By exploring the multiple facets of cassava wastewater use in agriculture.
