Description :
The chemistry of soils on the main channel and tributary floodplains are distinctly different. But the concentrations of basic cations and pH in these alluvial soils were always higher than those in the more common high-land (terra firme) soils. The main channel samples showed a decrease in cation concentration downriver. From the point of view of soil fertility, the Amazonian varzea show a high potential for agricultural development.
