Spatial variability of pH and Fe2O3 content in soils of the basin Tabure river in Lara State
The pH is a chemical property of the soil that represents, in general terms, its self- reaction, while iron in the form of Fe2O3 sets up a fraction related to the evolution degree of soils. With the purpose of knowing the variability of two chemical properties of the soils of Tabure river b...

| description | The pH is a chemical property of the soil that represents, in general terms, its self- reaction, while iron in the form of Fe2O3 sets up a fraction related to the evolution degree of soils. With the purpose of knowing the variability of two chemical properties of the soils of Tabure river basin in Lara state, namely pH and Fe2O3, a systematic soil survey was made in a grid of 100mx100m and classic statistic parameters were studied and one semivariography analysis with raw data. An omnidirectional semivariogram fitting to a spheric model with a range of 580m was obtained for pH and for Fe2O3 the best fit for an omnidirectional semivariogram was an exponential model with a range of 283m. In the case of pH a light anisotropy in direction nw-se was observed, while Fe2O3showed isotropic behavior. In conclusion the maximum variation distance of studied properties of soil was determined and a minor anisotropy of pH was recognized. These results are useful for future investigations about pH and Fe2O3spatial variability of soil in the studied basin. |

Con el fin de evaluar la variabilidad de dos propiedades químicas de los suelos de la cuenca del río Tabure del estado Lara, en especial el pH y el Fe2O3 se realizó un levantamiento de suelo sistemático en una malla de 100mx100m, y se estudiaron los parámetros estadísticos clásicos y un análisis de semivariografía con los datos brutos, obteniéndose un semivariograma omnidireccional ajustado a un modelo esférico con un rango de 580m; para el Fe2O3 se obtuvo el mejor ajuste para un semivariograma omnidireccional un modelo exponencial de 283 m, en el caso del pH se observó una ligera anisotropía en la dirección nw-se, mientras que el Fe2O3 tuvo un comportamiento isotrópico. En conclusión se logró determinar la distancia máxima de variación de las variables estudiadas y se reconoció la leve anisotropía del pH, éstos resultados son útiles en futuras investigaciones sobre la variabilidad espacial del pH y del Fe2O3 del suelo en la cuenca estudiadaUniversidad Técnica Estatal de Quevedo2018-07-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.uteq.edu.ec/index.php/cyt/article/view/21710.18779/cyt.v11i1.217Ciencia y Tecnología; Vol. 11 No. 1 (2018): Science and Technology Journal - January - June 2018; 19-27Ciencia y Tecnología; Vol. 11 Núm. 1 (2018): Revista Ciencia y Tecnología Enero - Junio 2018; 19-27Ciencia y Tecnología; v. 11 n. 1 (2018): Revista Ciencia y Tecnología Enero - Junio 2018; 19-271390-40431390-405110.18779/cyt.v11i1reponame:Revista Ciencia y Tecnologíainstname:Universidad Técnica Estatal de Quevedoinstacron:UTEQenghttps://revistas.uteq.edu.ec/index.php/cyt/article/view/217/215https://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccess2020-06-30T21:09:40Zoai:revistas.uteq.edu.ec:article/217Portal de revistashttps://revistas.uteq.edu.ec/index.php/cytUniversidad públicahttps://www.uteq.edu.ecEcuadorCiencia y tecnología1390-40431390-4043opendoar:2020-06-30T21:09:40falsePortal de revistashttps://revistas.uteq.edu.ec/index.php/cytUniversidad públicahttps://www.uteq.edu.ecEcuadorCiencia y tecnología1390-40431390-4043opendoar:2020-06-30T21:09:40Revista Ciencia y Tecnología - Universidad Técnica Estatal de Quevedofalse |
