“…As the DFAA has the above two periods, it demonstrates the yield reduction effects of extreme climate change. In the SJS, the yield was larger with the longer drought duration in the DFAA events, which can be explained as: (i) the drought has less impacts on the seeding period compared to other periods, which promotes root growth during the long-term drought, and in turn the deep roots can resist the drought [46]; and (ii) the root surface was larger in the moderate DFAA, which promotes nutrient absorption [47]. Previous studies showed that yield would slightly increase when the drought occurred in the seeding period [48].…”

Climate change, especially precipitation change, will significantly change soil moisture, which then influences root growth, further affecting yield and grain quality. Previous studies focused on the drought or flood effects on summer maize growth. However, few studied the effects of drought-flood abrupt alternation (DFAA) on the growth of summer maize. We explored the DFAA impacts on the roots, leaf area index (LAI), yield, and grain quality in field. The main results show that DFAA had different impacts on the summer maize growth in the seeding-jointing stage (SJS) and tasseling-grain filling stage (TGS). In general, the DFAA reduced the yield. Roots at the depth of 40 cm had obviously positive impacts on the yield. The DFAA reduced the LAI and promoted the maximum LAI achieving in advance. The grain crude protein augmented under DFAA. The drought had evidently negative impacts on the grain crude fat in the TGS, while it had no obvious influence in the SJS. DFAA had no apparent impact on the grain crude starch. These results could provide some references for the effects and adaptation-strategies study of extreme climate events and their impacts on growth of summer maize.

“…En la tabla 6, se muestra la concentración del ARA suelo impactado por 37620 ppm de ARA remanente de la BIO, luego mediante la FITO con S. vulgare potenciado con A. niger y P. chrysogenum que estimularon el sano crecimiento de las raíces, sugiere la conversión de los exudados radicales en fitohormonas 11,17,30, que aumentaron la cantidad de los pelos radiculares, para ampliar el área de exploración y absorción mineral, y con ello aumentaron la tolerancia de S. vulgaris al ARA 10 . Además de que existe la evidencia de que tanto A. niger como P. chrysogenum tienen la capacidad de degradar aromáticos del ARA 12,14,20,31 , y facilitaron la eliminación del ARA hasta una concentración de 3400 ppm, valor inferior al máximo establecido por la NOM-138, con lo que se logró la recuperación del suelo para su reutilización en la producción agrícola.…”

En México, un suelo agrícola pobre en nitrógeno (N) contaminado por un derivado de hidrocarburos como el aceite residual automotriz (ARA), con una relativa alta concentración de 100000 ppm, es un problema ambiental, pero también porque afecta drásticamente las propiedades del suelo asociadas con la mineralización de la materia orgánica y la pérdida de fertilidad, ya que sobrepasa el límite máximo aceptado de 4400 ppm de la norma mexicana llamada, NOM-138-SEMARNAT-2012 (NOM-138). Una alternativa de solución es tratarlo con acciones ecológicas para eliminar el ARA y recuperar esa fertilidad. Por lo que los objetivos de esta investigación fueron: i) biorremediación de suelo contaminado por 100000 ppm de ARA ii) fitorremediación mediante Sorghum vulgare con Aspergillus niger y Penicillium chrysogenum para decrecer el ARA a un valor inferior a 4400 ppm de la NOM-138. Para ello la recuperación de suelo se realizó mediante la variable-respuesta: desaparición del ARA por Soxhlet al inicio y después de la biorremediación y al final de la fitorremediación con S. vulgare con la fenología y biomasa a plántula. Todos los datos experimentales se validaron por ANOVA/Tukey HSD P<0.05%. Los resultados indicaron que la biorremediación y la fitorremediación del suelo contaminado por 100000 ppm de ARA, la decrecieron hasta 3400 ppm, valor inferior al máximo establecido por la NOM-138, suficiente para la recuperación del suelo en la producción agrícola, en 120 días un periodo de tiempo relativamente corto. 2020.

Global change refers to anthropogenic and climate pattern modification. The consequences of these changes are outstanding on aboveground biodiversity. Soil microbiota are key actors in soil processes, contributing significantly to numerous ecosystem services provided by soil. They are involved in the processes of nutrient cycling, organic matter decomposition, or pollutants degradation. Microorganisms are also able to synthesize volatile organic compounds that are secondary metabolites with multiple ecological roles and mechanisms of action—generally contributing to plant development. Changes in soil microbiota community could modify either negatively or positively their contribution in soil-provided ecosystem services through their involvement in soil functions that they mediate.
