Identificación de suelos del orden Inceptisol

Abstract

The description of soil profiles (agrological, geological and pedological level) was held at the Agricola Farm St. Francis University Foundation Juan De Castellanos, as a reference point of the municipality of Soracá - Boyacá, in order to meet the classification, physical conditions - chemical, natural fertility and soil management. With the application of the methodology SMSS - SDSS (USDA) or Soil Taxonomy, adapted by IGAC two test pits (JDC-CB1 and CB2-JDC) taxonomically classified as Humic Dystrustepts and Typic Dystrustepts they were made. These are soils of low fertility, high contents of Ca, K, Fe and low contents of Na, CIC, Mn and Zn, which should be improved with applications of N, P, S and MO (organic matter), according to the particular requirements implement crop in the agricultural area Soracá. The Consociation Cabrera (CB-Cbs) and the Bogota River Association (Rb-a), two mapping units were identified. AMVF1 (mountain areas and hills) and AMHA (floodplain). In addition, two formations. Physically chemical laboratory tests were made to soils with high clay content of the medium, high soil moisture, but with aeration and drainage problems. Additionally, they present a moderate and compacted structural stability (problems for agricultural work soil and moisture it should be adequate to prevent the structure is lost, since the state of aggregation is very high and soils are susceptible to hardening (hardpan). With the regional and local geology two formations: Bogota (Tb) and Tilata (Tst) were identified. In addition, three stratigraphic units (N2Q1Sc, E1Sc and K1-K6 stm) were defined.
