<abstract language="eng">The present research highlights the macronutrient abundance in the sediments of beaches and cliffs and cultivates in the river Purus and flowing, southwest of Amazon. The concentrations found in leaves and bean seeds and corn leaves reflect the mineralogical and chemical nature of those rich sediments in K2O and Na2O, which are formed by smectite, illite and K-feldspar. The factors of transfer of the elements in the corn leaves and bean (Ca>K>Na) and bean seeds (Na>K>Ca) demonstrate that the nutrient needs of the cultivate were found appropriately in the sediments (soils) of the beaches and cliffs.
