It is mainly located in the center of Brazil and corresponds to the whole Central Plateau. About 49% of the soils are Ferralsols and approximately 79.106 ha of these soils are dedicated to agriculture. The main characteristics of Ferralsols are a poor horizonation, a weak development of the macrostructure, and a strong submillimetric granular microstructure. specialized BRESIL 068 World Congress of Soil Science, 18., Philadelphie (USA), 2006/07/09-15 369 1IUSS/2International Union of Soil Sciences/5AUS ed. edt IRD Philadelphie IUSS 2006 https://www.documentation.ird.fr/hor/fdi:010072618 [F B010072618] https://www.documentation.ird.fr/hor/fdi:010072618 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers18-07/010072618.pdf IRD - Base Horizon / Pleins textes 2009-05-13 2018-08-09 fdi:010072618 fre
