description |
The aim of this study was to evaluate the Bouyoucos method, at different stirring times and using two chemical dispersants, for particle size determination and distribution in slightly alkaline soils of Córdoba, Colombia. Eight soils were mechanically dispersed applying a slow stirring; 60 rpm with five stirring times as follows: 2, 4, 6, 10 and 16 hours and a control experiment at 0 h. Chemical dispersion of samples was performed using two dispersants: Calgon (0.058 molL-1 (NaPO3)6 + 0.075 molL-1 Na2CO3) and a mixture of Calgon and 0.1 molL-1 Na4P2O7 at pH 9.1, which was proposed by authors. In addition, particle size distribution was determined by Pipette method, which was used as reference method. Tests of means and regression models were performed for sand, silt and clay contents using SAS statistical software. According to the results, significant differences were not found between 10 and 16 h of stirring, therefore maximum state of dispersion had achieved at stirring time of 10 h. Content of sand fraction showed an exponential decreasing which can be described following model given by y=a+be^(((-x)⁄c)), with determination coefficients higher than 0.90. Clay fraction showed exponentially increasing behavior of first order given by y=a-be^(((-x)⁄c)) with determination coefficients greater than 90%. Soil textural classification was performed by Bouyoucos method using the proposed dispersant at 10 h of stirring was 75% similar to that determined by Pipette method whereas for Calgon, was 62.5%. |

Para ello, ocho suelos fueron sometidos a un proceso de dispersión mecánica, que consistió en una agitación lenta, en un equipo tipo Wagner a 60 rpm con cinco tiempos de agitación 2, 4, 6, 10 y 16 horas y un testigo a 0 h. La dispersión química de las muestras se realizó utilizando dos dispersantes; Calgon ((NaPO3)6 0.058 M + Na2CO3 0.075 M) y una mezcla compuesta de Calgon más pirofosfato ((NaPO3)6 + Na2CO3) + (Na4P2O7)) 0.1 M a pH 9,1. Además, a las muestras se les determino la granulometría por el método de pipeta. Las pruebas de medias y modelos de regresión de los contenidos de arena, limo y arcilla fueron analizados usando el software estadístico SAS. De acuerdo a los resultados obtenidos, no se encontró diferencias significativas entre las 10 y 16 h de agitación, por lo tanto 10 h son suficientes para obtener un máximo estado de dispersión. El contenido de la fracción arena presentó un decrecimiento exponencial que siguió el modelo y=a+be^(((-x)⁄c)), con coeficientes de determinación superiores a 0.90. La fracción de arcilla presentó un comportamiento exponencial creciente de primer orden, y=a-be^(((-x)⁄c)) con coeficientes de determinación mayores del 90%. La clasificación textural por Bouyoucus con el dispersante propuesto a 10 h de agitación fue 75 % similar al determinado por el método de pipeta, y para el Calgon fue 62.5%.application/pdfspaUniversidad Nacional de Colombia Sede Palmirahttps://revistas.unal.edu.co/index.php/acta_agronomica/article/view/60762Universidad Nacional de Colombia Revistas electrónicas UN Acta AgronómicaActa AgronómicaCombatt-Caballero, Enrique Miguel and Palencia- L., Manuel and Borja-M, Katerine (2018) Particle size distribution by Bouyoucos in slightly alkaline soils from department of Cordoba, Colombia.
