This zone has specific characteristics, such as low altitudes, high temperatures, and, in some parts, restricted water regimes. The soils are highly weathered and acidic, with low buffering capacity, low organic matter (OM) content, and considerable occurrence of sandy or gravelly soils. The combination of these edaphoclimatic conditions results in low capacity to retain nutrients and water.  aClimate  aCultivation area  aEdaphic factors  aSoil classification  aSoil fertility  aSoil water characteristic  aClima  aConsorciação de Cultura  aGlycine Max  aMilho  aPlanta de Cobertura  aSoja  aSolo  aZea Mays  aCultura de cobertura  aDesenvolvimento da agricultura  aFronteira agrícola no Brasil1 aSOUZA, H.
