Literature review evaluates vinasse effects on soil quality in fertigation, suggesting sustainable applications.
Vinasse is a liquid effluent generated as by-product of the fractional distillation of fermented sugarcane juice during ethanol production. When properly managed, vinasse can be used in fertigation, offering significant benefits to agricultural production. This review aims to evaluate the effects of vinasse application on fertigated crops and soil quality. This exploratory study involved a literature review of scientific articles and books using the keywords “fertigation” and “vinasse”. When applied as a fertilizer, vinasse can positively influence the physical, chemical and biological properties of soil. The results indicated that vinasse contains essential nutrients that contribute to plant growth. To support its appropriate application, a general equation for calculating the fertigation rate is also presented. The Vinasse Application Plan should include a descriptive report outlining the fertility characteristics of both the soil and the vinasse, along with the calculated application rate. Literature indicates that the use of irrigation equipment for vinasse fertigation in sugarcane cultivation is a technically and economically viable practice. When applied judiciously, this strategy supports the sustainable management of vinasse while minimizing potential environmental impacts.
