This study aimed to determine the effects of chicken compost and KCl fertilizer application on the growth, yield, post-harvest quality of sweet corn (Zea mays L. var. saccharata), soil respiration and microbial population. The research was arranged according to a Factorial Random-Block Design consisting of two factors and three replications. The first factor was the dose of chicken compost (0 and 15 t/ha) and the second the dose of KCl fertilizer (0, 50, 100 and 150 kg/ha). The results showed that chicken compost stimulated the growth, yield, postharvest quality of sweet corn, respiration, and microbial activity of soil. KCl fertilizer increased SPAD values linearly and quadratically chlorophyll pigment, β-carotene, yield components, and yield. KCl fertilizer did not affect soil respiration, fungi, or bacteria populations. The use of chicken compost reduced the need for KCl fertilization by 25%. Therefore, the integration of organic and inorganic fertilizers are recommended to be applied by farmers in the tropics.

“…La contaminación de suelos por la introducción del Pb y Cd se debe principalmente a eventos relacionados a los procesos industriales como: derrames, transporte, pérdidas de mermas y generación de residuos sólidos (Prasetia et al, 2017), lo cual genera riesgos sobre la calidad de los recursos, los alimentos y la salud humana (Chabukdhara y Nema;Naveedullah et al, 2013). Al respecto, diversos estudios han demostrado la degradación de suelos por Pb y Cd (Mudd, 2010), debido al empobrecimiento de sus nutrientes lo cual dificulta la actividad microbiana, afectando negativamente a los cultivos (Upadhyay et al, 2016). Aunque existen diversos métodos para el tratamiento de estos suelos, muchas veces las interacciones de estos metales con otros componentes dificultan su limpieza haciendo el tratamiento más costoso (Cameselle y Gouveia, 2019;Delgadillo et al, 2011).…”

Con la finalidad de reducir la contaminación por metales pesados en suelos agrícolas, decidimos evaluar el efecto de las enmiendas orgánicas (compost y vermicompost). Se realizó el trabajo utilizando girasol como fitorremediadora. Para ello se emplearon los suelos agrícolas de las localidades Mantaro y Muqui del valle del Mantaro. Los resultados indican que los suelos de la localidad de Muqui, contienen la mayor cantidad de Pb y Cd, presentando efectos negativos en la producción de biomasa. La planta de girasol absorbe los metales pesados como lo demuestra la mayor acumulación de plomo y cadmio en la raíz de ésta, no se encontraron diferencias significativas entre la acumulación de plomo en tallos y flores, tallos y hojas, para cadmio en los tallos y hojas, confirmando que la aplicación de las enmiendas orgánicas contribuye a solubilizar el Pb y Cd del suelo, además de contribuir en un mayor desarrollo del cultivo. Los valores del Factor de Bioconcentración (FBC) de Cadmio (0,53-0,66) fueron mejores que el plomo (0,07-0,08), mientras que los valores del Factor de Translocación (FT) indicaron una capacidad del girasol como un fitoestabilizador, especialmente con el uso de vermicompost (Pb: 1

“…These activities are major causes of soil degradation and contamination and thus pose a great challenge for food safety and public health ( Qishlaqi and Moore, 2007 ; Tripathi et al, 2012 , 2015 , 2016b ). Soils of mining sites have extremely high percentage of heavy metals such as chromium, lead, cadmium, and arsenic which cause destruction of soil properties such as pH, nutrient content and quality ( Ladwani et al, 2012 ; Hansda et al, 2014 ); thereby, significantly affecting the fertility of surrounding soil, associated microbial community, vegetation status as well as pose several health risks at different levels of food chain through a well-established process of bioaccumulation ( Wuana and Okieimen, 2011 ; Upadhyay et al, 2016 ).…”

“…Hexavalent (Cr (VI)] is mainly released in environment through various anthropogenic activities and imparts toxic effects on microorganisms, human beings and soil fertility ( Oliveira, 2012 ; Tripathi et al, 2012 ; Ahemad, 2015 ). It is well documented that bacterial composition is greatly affected by soil type, its characteristics and stress factors which restrict the bacterial growth in soil ( Upadhyay et al, 2016 ). Only a few bacteria may adapt to these stressed environments and proliferate.…”

Tolerance and Reduction of Chromium(VI) by Bacillus sp. MNU16 Isolated from Contaminated Coal Mining Soil

et al. 2017

The bacterium MNU16 was isolated from contaminated soils of coal mine and subsequently screened for different plant growth promoting (PGP) activities. The isolate was further identified by 16S rRNA sequencing as Bacillus subtilis MNU16 with IAA concentration (56.95 ± 0.43 6μg/ml), siderophore unit (9.73 ± 2.05%), phosphate solubilization (285.13 ± 1.05 μg/ml) and ACC deaminase activity (116.79 ± 0.019 μmoles α-ketobutyrate/mg/24 h). Further, to evaluate the metal resistance profile of bacterium, the isolate was screened for multi-metal resistance (viz. 900 mg/L for Cr, 600 mg/L for As, 700 mg/L for Ni and 300 mg/L for Hg). Additionally, the resistance pattern of B. subtilis MNU16 against Cr(VI) (from 50 to 300 mg/L) treatments were evaluated. An enriched population was observed at 0–200 mg/L Cr(VI) concentration while slight reductions were observed at 250 and 300 mg/L Cr(VI). Further, the chromium reduction ability at 50 mg/L of Cr(VI) highlighted that the bacterium B. subtilis MNU16 reduced 75% of Cr(VI) to 13.23 mg/L within 72 h. The localization of electron dense precipitates was observed in the TEM images of B. subtilis MNU16 which is might be due to the reduction of Cr(VI) to Cr(III). The data of fluorescence microscopy and flow cytometry with respect to Cr(VI) treatments (50–300 mg/L) showed a similar pattern and clearly revealed the less toxic effect of hexavalent chromium upto 200 mg/L Cr(VI) concentration. However, toxicity effects were more pronounced at 300 mg/L Cr(VI). Therefore, the present study suggests that the plant growth promoting potential and resistance efficacy of B. subtilis MNU16 will go a long way in developing an effective bioremediation approach for Cr(VI) contaminated soils.
