Efeito da aplicação de vinhaça nas propriedades do solo e a produtividade da cana-de-açúcar

Abstract

Sugarcane cultivation has high economic and energy relevance in Brazil, especially due to ethanol production, which generates large volumes of vinasse as a byproduct. In this context, this study aimed to analyze the influence of vinasse application on soil properties and sugarcane productivity. The research was conducted through a qualitative bibliographic review, based on scientific articles, dissertations, theses, and technical documents published in recognized databases. The results indicate that vinasse application promotes significant changes in the chemical, physical, and biological attributes of the soil, highlighting the increase in nutrient availability, especially potassium, as well as improvements in organic matter, water retention, and soil structure. On the other hand, continuous use or high application rates may cause negative effects, such as increased salinity, changes in soil microbiota, and compaction in subsurface layers. Regarding productivity, an increase in stalk yield was observed, mainly associated with improved soil fertility. It is concluded that vinasse can be an efficient input in sugarcane production systems when properly managed based on technical criteria, contributing to agricultural sustainability.
