The effect of K fertilization on quality of sugarcane
juice is ambiguous, some authors reported that the
addition of K to the soil does not significantly affect
the technological characteristics of sugarcane (Uchôa et
al., 2009; Silva, 2010), and others indicate significant
effects of K fertilizer on the technological characteristics
of sugarcane (Orlando Filho et al., 1993; Silva, 2010).
Since it is not possible to generalize, it is necessary to
generate experience to K managing for each sugarcane
region.
