Aspectos hídricos de alguns solos da Amazônia - Região do baixo rio Negro

Abstract: ResumoNo presente trabalho, é feito um confronto entre os dados clímatológicos, a água disponível e a conduti· vidade hidráulica saturada de nove perfis de solos da região do baixo rio Negro, no Estado do Amazonas. Os resultados tendem sugerir a presença de uma relativa. mente baixa capacidade de armazenamento de água disponlvel nos perfis de solo estudados. Em média a condutlvldade hidráulica saturada é representada por 35 mm; hora, concluindo-se que chuvas com intensidade igual ou maior do que 35 mmj hora pr… Show more

“…Considerable annual variation has been noted in rainfall and in total solar in solation and net radiation, both of which accent the variability of rainfall (Salati et al 1978;UNESCO 1978, p. 43). Unpredictable periods of water deficiency occur in the humid tropics in part resulting from the rapid water percolation found in some tropical soils, and in part due to the high rate of rainfall per hour (Reichardt et al 1980). High levels of solar radiation may also be partly responsible for seasonal deficiencies in water supply to plants.…”
