Short summary
The study refers to a survey of the attributes of the main soil classes of the state of Pará, an eastern Amazon region in Brazil. These soils have good potential for agricultural use under natural conditions. In this study we observed that the soils are predominantly kaolinitic, but have relatively low aluminum and organic matter contents, with huge textural variability. The results enable a better understanding of eastern Amazonian soils, whose area reaches more than 1.2 million km2.
