Production And Characterization Of Twelve Different Biochars And Evaluating Their Effects On Soil Health And Plant Growth, Shagufta Gaffar Nov 2020

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 …


Inoculating Rhizobium And Arbuscular Mycorrhizal Fungi On Snap Bean Under Salinity Stress To Study Plant Growth And Glomalin Production Effects, Claudia Lyl Garcia Jun 2019

Inoculating Rhizobium And Arbuscular Mycorrhizal Fungi On Snap Bean Under Salinity Stress To Study Plant Growth And Glomalin Production Effects, Claudia Lyl Garcia

FIU Electronic Theses and Dissertations

Groundwater salinization from saltwater intrusion threatens Southeastern Florida’s commercially important snap bean (Phaseolus vulgaris) production because of the crop’s low salt-tolerance threshold. The present study was carried out to determine if co-inoculating salt-stressed snap beans with beneficial microbial symbionts (i.e., Rhizobium and arbuscular mycorrhizal fungi) can mitigate growth reductions. Additionally, the study also assessed whether co-inoculation had an effect on the production of glomalin, a protein secreted by arbuscular mycorrhizal fungi that improves soil aggregation. Snap beans were inoculated (-AMF/-Rhizobium, +AMF/-Rhizobium, +AMF/+Rhizobium) and irrigated with varying salinity levels (0.6, 1.0, 2.0 dS …
