Efecto De La Adición De Biochar Como Enmienda De Un Suelo Degradado, Sobre Microorganismos Relacionados Con El Ciclo Del Carbono, Johan Alejandro Burbano Chinchajoy

Biología

Actualmente, la fuerte demanda agrícola y las malas prácticas han alterado el equilibrio natural del suelo, así como las interacciones físicas, químicas y biológicas, ocasionando su degradación del suelo; por tanto, los índices de calidad del suelo son considerados como herramientas para evaluar el estado de este sustrato en condiciones naturales o el utilizado para la producción agrícola.

Una de las prácticas utilizadas para mitigar su degradación es el uso de enmiendas orgánicas, como el biochar, a nivel mundial se ha evaluado su adición como medio para mejorar la fertilidad del suelo y mitigar el cambio climático, además, sus efectos …

Production And Characterization Of Twelve Different Biochars And Evaluating Their Effects On Soil Health And Plant Growth, Shagufta Gaffar

FIU Electronic Theses and Dissertations

Biochar has been a topic of growing interest in the scientific community. It is a product derived from carbon rich organic materials through the process of pyrolysis. It has received wide attention as a means to improve soil fertility and crop productivity, absorb pollutants in soil, and sequester carbon to mitigate climate change. Recent research on biochar explores its impacts on the environment with particular focus on use as a soil amendment in agriculture. Biochar produced from different biomass and under different production process effects the environmental and agronomic impacts of its application in different ways. This means biochar can …

Evaluation Of The Symbiotic Relation Between Endophyte And Poplar Trees Exposed To Landfill Leachate, Catalina Vega Hurtado

Masters Theses

“The contamination of soil and groundwater from leachate leakage from landfill has turned, nowadays, into a global public issue. One of the main concerns about this pollutant is the potential threat to human and ecosystem health. The current research studied endophyte bacteria in association with poplar trees (Populus sp.), as a method of bioremediation of landfill leachates. The objective of the project was to identify treatment strategies that may improve plant performance (survival rates, plant fitness, and degradation efficacy) with the purpose of being implemented in phytoremediation plots, aimed to intercept and treat landfill leachate, before the contamination of watershed. …

Biochar And Vermicompost Amendments In Vegetable Cropping Systems: Impacts On Soil Quality, Soil-Borne Pathogens And Crop Productivity, Nathan Lee Shoaf

Open Access Theses

Amending soils with biochar and vermicompost has the potential to provide multiple benefits for specialty crops including pathogen suppression and increased crop productivity. Oomycete pathogens such as Phytophthora capsici can devastate crop fields and they are difficult to control presenting significant management challenges for Midwestern growers. Soils amended with a microbially-inoculated softwood biochar increased carrot root growth relative to the control and corn stover biochar in 2011, while the corn stover biochar also increased carrot root growth relative to the control, but only in two varieties. Neither biochar treatment influenced carrot growth in 2012. In greenhouse trials, vermicompost amendments provided …
