B 2.5. Is there any regulation controlling the use of vinasse as a fertilizer for the crop?
Vinasse is a sub-product of the sugarcane distillation. Many years ago it was recognized that vinasse could be a valuable organic fertilizer (replacing potassium) and an important source of replacement water for the soil. Hence it has been used by the sugarcane industry in fertirrigation, replacing salts and other nutrients extracted by the sugarcane during growth and maturing. Fertirrigation, besides offering great benefits by reducing the need to use water and chemical fertilizers, is also an economical and sustainable way to recycle this sub-product.
