Abstract In comparison of modified nanoscale zero-valent iron (NZVI), bare NZVI used to remediate deep contaminated groundwater source areas has more advantages. However, the influences of injected bare NZVI deposition on the permeability of aquifer remain unclear, which are still the key factors of engineering cost and contamination removal. Hence, this study sought to assess method of measuring hydraulic conductivity with constant head device and examine the permeability loss mechanism of NZVI injected into different saturated porous media, using column tests. The results showed that it was feasible to determine hydraulic conductivity by the constant head device. The permeability loss caused by NZVI injection increased with a decrease in grain size of porous media, and was determined by the amount and distribution of NZVI deposition. NZVI distribution area had a good linear correlation with dispersivity of the porous media. Additionally, although surface clogging occurred in all porous media, the amount of NZVI deposition at the injection point in fine sand was largest, so that its permeability loss was the most, which was more likely to cause hydraulic fracturing and then expand the area of contaminant source zone. These results have implications for NZVI field injection to successful groundwater remediation.

Objetivo: Evaluar el desarrollo de plántula de tomate indeterminado bajo condiciones protegidas, aplicando  tres enraizadores  y un testigo para aumentar la producción del cultivo en la región. Diseño/metodología/aproximación: se utilizó bajo un diseño experimental en bloques completamente al azar, el cual consistió de cuatro tratamientos correspondiendo a cada uno de los bloques, donde cada bloque pertenecía a cuatro charolas de unicel de 200 cavidades con sustrato de BM2, con cuatro repeticiones cada uno, teniendo 15 unidades experimentales por tratamiento, sumando un total de 60 unidades experimentales, teniendo un total de 240 plántulas de tomate por todo el experimento. Resultados: Como resultado se obtuvo que el enraizador de Phyto Root  tuvo un gran efecto en cuanto al desarrollo de altura, grosor de tallo, numero de hojas, biomasa aérea y peso del cepellón, parámetros importantes que debe tener una plántula para su desarrollo y crecimiento al momento de trasplante a campo. Limitaciones del estudio/implicaciones: El manejo agronómico desde la siembra en charolas, es necesario que sea uniforme en todos los tratamientos y las repeticiones para tener mejores resultados en cuanto el efecto de los enraizadores. Hallazgos/conclusiones: Para obtener plántulas de buena calidad en el momento de trasplante a campo se le recomienda a la empresa y a los productores de plántulas utilizar el tratamiento de Phyto Root, ya que fue la que mejor respuesta tuvo.
