Areas constituted by sandy sediments, near Iquitos, have been studied extensively, these geological materials, originated different soils taxonomically, depending on the biophysical conditions in which they were developed. Four soils of the zone of Zungarococha, located to the south west of the city of Iquitos were studied. The present work was based on the identification and characterization of the diagnostic horizons of the indicated soils, in order to explain their nature and properties. The descriptions of the soils were carried out following the guidelines of the Soil Survey Manual (1993). Also, the mineralogy was determined using the technique of X-Ray Diffractometry. The results found, show the existence of soils with deep profiles and presence of albic diagnostic horizons overlapping the spodic diagnostic horizons. The spodic horizons present an accumulation of organic matter and iron, whereas in the albic horizons the organic matter contents are below those that present the spodic horizons, these characteristic found, indicate that the dominant process in these soils, was the Podsolization, which allowed them to be classified in the order Spodosols (Soil Taxonomy, 2014). Mineralogically the horizons of albic and spodic diagnosis presented quartz as the dominant mineral, and within them cristobalite and silicon oxides, which are related to the genesis of Spodosols developed in the humid tropics rich in quartz. In conclusion, the diagnostic horizons of the soils characterized and identified, meet some of the physical and chemical conditions that allow us to know the soil variability and to have elements of judgment to support the nature and properties of the spodosols developed under conditions of the Peruvian humid tropic.
