Resumo: Samples of a savannah dystroferric Oxisol were collected from three management systems, incubated with lime to 0%, 60% and 100% base saturation, and with agricultural gypsum to 0 kg ha-1, 500 kg ha-1, 1,000 kg ha-1 and 2,000 kg ha-1. A completely randomized 3x3x4 factorial experimental design was used, with four replications. After lime and gypsum application, soil samples were incubated for 45 days. Afterwards, physical and chemical analyses were performed. Independently of the soil management system, a close inverse correlation (r = -0.9801; p < 0,01) between water dispersed clay content (WDC) and flocculation degree was observed. In soil samples collected from annual crops without liming WDC values were higher than for forage and native savannah vegetation. Soil liming for forage, at 60% base saturation, promoted increase in aggregates greater than 1.0 mm. Gypsum increased flocculation, no matter rates or soil use. KEY-WORDS: Soil management; liming; gypsum.

Amostras de um Latossolo Vermelho Distroférrico, coletadas sob três condições de uso, foram incubadas com calcário, em doses para a obtenção de 0%, 60% e 100% de saturação por bases, e com gesso agrícola, nas doses 0 kg ha-1, 500 kg ha-1, 1000 kg ha-1 e 2000 kg ha-1. Utilizou-se o delineamento experimental inteiramente casualizado, em esquema fatorial 3x3x4, com quatro repetições. Após a aplicação dos corretivos, as amostras de solo foram incubadas por um período de 45 dias. Em seguida, procederam-se as análises físicas e químicas especificadas. Observou-se que, independentemente do uso do solo, houve uma correlação inversa (r = -0,9801; p < 0,01) entre os valores de argila dispersa em água (ADA) e o grau de floculação. Em solos submetidos a culturas anuais, sem o uso de calcário, obtiveram-se maiores valores de ADA que naqueles submetidos à pastagem ou sob vegetação nativa. A calagem em solos sob pastagem, com doses para elevação da saturação de bases a 60%, proporcionou aumentos nos valores de agregados maiores que 1,0 mm. O gesso induziu aumentos no grau de floculação, independentemente da dose ou do tipo de uso do solo. PALAVRAS-CHAVE: Manejo do solo; calagem; gessagem.
