) Well, my friends, I have come to talk a bit about the geology of the fields. I was doing a little research and this is what I found. I hope you like it and the photo was taken by me with a sirago-5000 camera. I hope you like it and thank you for supporting me. @jesusalbertorios
The entire surface of the eastern plains is composed of alluvial sediments of Andean origin (Goosen 1964, Brunnsch-Weiler 1972), within the plains you can distinguish wide geological regions: to the north and west of the river Meta, there is marine deposit resent of age pleistocenica, and to the south and east lies the altillanura, expansive sediments of superior tertiary and lower quaternary origin (Ingeominas 1976.
The distribution of the soils is presented in accordance with the subdivision by large landscapes. The most important for their extension are Paleudutls - Paleustults, Haplorthox, Dystropept and Quatzipsamment, in well drained areas, and Plintaquept, Tropaquepts, Tropaquents and Umbraquox in areas with poor drainage. 
) - The polycyclic character of the materials from which the soils have been developed in the Llanos, is the main responsible for their mineral and chemical characteristics. In general, they are soils that present a high degree of evolution, which is manifested in the predominance of quartz in the sand and kaolinite fraction and iron oxides in the clay fraction; low base content, acidic pH, high levels of aluminum in the exchange complex. -
Four soil degradation processes have been described in the area, namely: surface compaction by trampling cattle, laminar erosion, in well-drained soils; reticular erosion, in the poorly drained soils of the basins in the alluvial overflow plain and solifluxion phenomena in areas covered by loess mantles (Botero 2003).
