Resumo: | ABSTRACT: This paper presents the strategic importance of potassium (K) in Brazil, focusing four aspects: the function in the plant; the K content of Brazilian soil; the different K forms; and its demand in the Brazilian agricultural system. The K is not a structural element of plants, but it participates in many biochemical plant processes, like carbohydrates and proteins synthesis, showing its economical importance in terms of production. A major problem in Brazilian soils is the leaching process due to the rain regimes. Since k is a very soluble ion in the soil profile, it must be replaced in regular basics to the culture. There are five sources of K, all them of high solubility. Less soluble K compounds have been studied as a way to minimize the leaching problem. Brazil imported 88,5% of the K consumed in 2002, coming from Canada, Germany, Russia and Israel. The organic agriculture and pasture reclamation are rising as potential markets for new forms of K.
