The study addresses soil contamination by hydrocarbons and the need to find effective remediation methods. The objective is to evaluate the efficacy of urea addition technique in contaminated soils. The study methodology was experimental and quantitative, utilizing the nutrient degradation method (urea) and landfarming. Five cells with 15000 grams ...
The study of the freshwater-saltwater interface zone (FWSWI) is fundamental for the characterization of coastal aquifers and the evolution of freshwater reserves. In this work we study the factors that condition the dynamics of the IADAS in the locality of Pinamar. To carry out this task, a monitoring borehole was drilled on the coastal front, elec...
Resumen: Dado la presión por urbanizar áreas con presencia de suelos salino-sódicos (SSS) alrededor del ex lago de Texcoco, México, es importante encontrar estrategias para arborizarlas. El objetivo del estudio fue determinar la respuesta de cinco especies arbóreas; Pinus greggii, P. pseudostrobus, P. ayacahuite, P. leiophylla y como especie de ref...
Resumen: En un invernadero de la costa de Oaxaca, se evaluó la tolerancia de los pastos híbridos del género Brachiaria: Cobra (BR02/1794), Cayman (BR02/1752), Camello (GP 3025) y Mulato II (CIAT 36087) a condiciones salinas inducidas por NaCl, MgCl2 y NaHCO3 y siete niveles de salinidad: 0, 1.13, 2.48, 3.84, 5.19, 6.40 y 9.60 g L-1.

Stingless bees play an important role in maintaining the balanceof the ecosystems they inhabit by actively participating in the pollinationof most flowering plants. The objective of this study was to characterizephysicochemically honey from the stingless bee speciesScaptotrigonamexicanafrom Fortín de las Flores, Cañada Blanca, and Manuel León, inVe...
The presence of groundwater chemical zonation related to Chebotarev sequence in general is presented in lateral dis-position from the recharge to the discharge zone. In the coastal aquifer in the Partido de La Costa, Buenos Aires, a vertical chemical zonation was detected. The aim of this work was to evaluate the behavior of the interface in the ve...
The use of mathematical models to study complex systems such as physical and biological phenomena allows understanding their behavior, specifically regarding variables and parameters that are difficult to obtain. Additionally, studying optimization techniques has made it possible to approximate the characteristics of these systems by correlating nu...
Resumen: El aprovechamiento de los residuos en los sistemas de producción agrícola, exige el utilizar diferentes abonos orgánicos para encontrar los niveles de aplicación y sus posibles combinaciones que produzcan cultivos de calidad. El objetivo de este estudio fue evaluar los efectos del estiércol bovino (EB) y vermicompost (V) en el suelo, así c...
Introduction. In carrot cultivation direct sowing is practiced because the seedling cannot resist the stress of transplanting. It is essential to use seeds that germinate in a maximum of seven days and uniformly. Seeds vigor is associated with yield performance in the field and, at the international level there are different test to measure it. How...
