| Abstract | The objectives of this study were to determine the chemical fractions of Fe, Cu, Mn, and Zn in soils of the upper Rio Negro Valley, and to analyze their relationships with some physical and chemical soils properties. Soil samples were taken at 0-25 cm depth in seven (Typic Torrifluvents) and seven (Typic Haplocambids). Through sequential extractions, the following micronutrient forms were quantified: exchangeable, bound to carbonates, adsorbed to organic matter (OM), residual, and total. Results indicated that 90% of the all studied micronutrients were bound to the least available fraction (residual). The increment of organic matter and phosphorus fertilization increased the more labile Zn, Mn, Cu and Fe forms. |
