In order to correct the increasing S deficiencies and bridge projected S gaps, there is a need to identify, develop, evaluate, and transfer fertilizer S technology and strategies that would be appropriate, technically and economically, for tropical countries of the world. Alternative S supply strategies include conventional S-containing fertilizers, modified S-containing fertilizers, and indigenous S supply sources such as native S, gypsum, phosphogypsum, and pyrites. The purpose of this chapter is twofold: (1) to briefly discuss various S supply sources, including S-containing fertilizers and soil amendments and (2) to discuss appropriate S supply strategies in the context of developing tropical countries.
