Caracterización de las propiedades físicas del suelo en un transecto altitudinal del refugio de vida silvestre Yankay

Abstract

The objective of the present investigation was to characterize the physical properties of the soil in an altitudinal transect of the Yankay wildlife refuge. The methodology implemented had a mixed approach with a descriptive and exploratory level, for sampling the area was subdivided into 6 sample units and the stratified method was used randomly, carrying out 15 subsamples for each sample unit, a documentary and field investigation was carried out to obtain the respective information through methods, techniques and instruments, among which were pits, laboratory, manual for visual evaluation of soil quality and the use of geographic information systems (GIS). Once all the characterization techniques were applied, it was obtained that the horizons that predominate in the study area are A and E, according to the physical properties, the predominant structure was granular, they have a sandy loam and silty loam texture, their porosity is medium high, the depth found is shallow soils with low resistance to penetration, finally, the color identified was 10YR which indicates humic, fulvic and quartz minerals, presenting a moderate to good soil quality. It was concluded that, despite human intervention in certain sample units, the physical properties of the soil have been adequately preserved, which demonstrates its ability to maintain quality despite changes in use.
