Brazilian sugarcane growers apply relatively few industrialized fertilizers, especially when compared to other crops. Brazilian sugarcane makes widespread use of organic fertilizers obtained as part of sugarcane processing. Mills recover residues called filter cake (which is rich in phosphorus) and vinasse (loaded with potassium, organic matter and other nutrients), which they then use in replacement of traditional fertilizers.
Vinasse and filter cake are one of the natural and circular solutions to promote improved soil health and reduce reliance on chemical fertilizers.
