TEXT OF THE ABSTRACT (NO
MORE THAN 400 WORDS).
Brazilian soils are very contrasting in
relation to fertility and the main soil classes have low levels of K.
Agricultural activities, mainly grains production in Brazilian Cerrado, demand
high amounts of K. The most K fertilizers are imported playing important role
in crop production costs. Although is common the inadequate use of K
fertilizers that may result in environmental contamination. Thus, since 2001
Embrapa and the International Potash Institute (IPI) have kept collaboration to
study K behavior to optimize potassium fertilizers application in
