Conteúdo:	Farmers in the Manaus region prefer concentrated fertilizer sources to minimize the high transportation costs from southern Brazil. Ordinary superphosphate, therefore, has seldom been used on these acid Oxisols, despite indications that the gypsum in this P source effectively reduced subsoil acidity and promoted deeper root growth in strong ustic soil moisture regimes. An ongoing study in the Typic Acrothox has compared the acid-ameliorating effects of lime and gypsum for com, cowpea and soybean for three consecutive years.
