“…The locations of the field tests are shown in Figure 2A, while Figure 3 shows the map with the reclassified data according to Table 1. The values of the magnitude of the soil parameters are similar to Aoki and Sereno (2005) and White and Sully (1987), who worked with pressure 1 cm in a loam soil, obtaining values of hydraulic conductivity (Ko) of 12.6 m h -1 ). Smettem et al (1994), estimated a Ko of 56 mm h -1 using a sandy loam soil, with a water application pressure of 2 cm.…”

“…Metodología de clasificación de la permeabilidad (Cisneros, 2001). We collected infiltration information by using a minidisc portable tension infiltrometer, The minidisk allows the quantitative identification of the relative contribution of the key hydrodynamic parameters that depend on the flow of infiltrated water and pressure during the water application, which is the unsaturated hydraulic conductivity (Angulo-Jaramillo et al, 2000;Aoki & Sereno, 2005;Wilson & Luxmoore, 1988). The infiltrometer is fixed to the ground with a ring to create tension between the soil and the water in the tank so that measurements can be performed based on the time elapsed to infiltrate all water contained in the tank, The potential is controlled by a cylinder bubbler connected to the reservoir (Ruiz Sinoga et al 2003).…”

“…This is a very important advantage on hillsides or where the slope is high, approximately 20 %. Fieldwork using the minidisc has been successfully carried out by Zhang (Aoki & Sereno, 2005;Ruiz Sinoga et al, 2003;Zhang, 1997;Zhang et al, 1999).…”

The generation of permeability maps is based on the analysis and interpretation of geology, environmental morphology, land use, and slope, which enables the selection of sampling areas with similar characteristics. The method represents the integration of the physical characteristics of the study area and then determines the infiltration capacity differences in the most representative geopedologic units. In determining the basic data, minidisc infiltrometers were used to perform seventy-two infiltration tests in different types of soils with varying organic matter content, texture, soil structure, and vegetation cover, which showed the spatial variability that exists in two cantons of Loja province, Ecuador. In addition, it was observed that the infiltration rate depended mainly on the content of the organic matter in the soil and is consistent with information collected on permeability worldwide. In this study, generated pedotransfer function (FTP) coefficient of determination R2 0.78, the determination of the coefficient indicates a satisfactory estimate of the permeability with the variables that were analyzed; in addition, the methodology for assessing the permeability was suitable for the conditions of this investigation. For this reason, the method described here should be tested in other areas of the country with a greater number of field trials and with more variable contents of organic matter and soil textural classes.

“…La infiltración fue medida por duplicado en cada una de las 18 parcelas experimentales con un infiltrómetro de disco. Se reguló la presión del infiltrómetro a -2 cm de presión (Aoki y Sereno, 2005). Se tomaron mediciones de infiltración hasta incluir intervalos de tiempo en los que el sistema se situó en un estado estacionario.…”

Se evaluó sobre el suelo el efecto de diferentes compost, obtenidos mediante igual metodología de compostaje, después de dos años de aplicados. Sobre un suelo Haplustol típico se aplicaron 40 Mg ha-1 de cada compost, conformando los siguientes tratamientos: CBIO con compost de biosólidos, CF con compost residuos de estiércol bovino, CG con compost de guano de gallina, CROU con compost de residuos sólidos urbanos. También se incluyó un tratamiento con fertilizante inorgánico (FI) y un suelo no tratado o control (C0). El pH del compost afectó ligeramente el pH del suelo, según las características del compost usado. CROU y CBIO incrementaron y disminuyeron el pH, respectivamente (R2=0,98). Se observó un cambio en la distribución de la materia orgánica del suelo CG, sin incremento en el carbono orgánico total (COT). En CG aumentó un 85 % el Cfraccion>53um y creció en 24 % el C extractable en álcali, respecto al control. Finalmente, se observó un enriquecimiento de CuM y ZnM en CROU. Los resultados muestran que una única adición de compost puede modificar las propiedades del suelo dado los múltiples materiales compostados. Se debe monitorear tempranamente las condiciones del suelo para identificar tendencias y evitar efectos ambientales negativos.
