The Diverse Effects Of Continual Organic Inputs On Soil Biogeochemical Properties And Microbial Communities In Sandy Ultisols Under Organic Production, Zhine Wang Dec 2024

The Diverse Effects Of Continual Organic Inputs On Soil Biogeochemical Properties And Microbial Communities In Sandy Ultisols Under Organic Production, Zhine Wang

All Dissertations

The objectives of this study were to understand how continual organic amendment inputs improve Nitrogen (N) cycling, microbial diversity and functional traits. Fully crossed factorial experiments were designed to test four cover crop treatments (cereal rye, hairy vetch, mixture of the rye and vetch, and no cover crop fallow) and two levels of manure compost application (with manure application and blank control) in organic vegetable production from 2020 to 2023. Cover crop biomass, soil chemical and biological properties were analyzed for the distribution and availability of soil labile N (Chapter 2), the abundance of N-cycling genes (Chapter 3), the structure …


Enhancing Crop Resilience: Physiological And Omics Approaches For Drought And Heat Stress Tolerance In Soybean And Peanut, Jyoti Prasad Kakati Aug 2024

Enhancing Crop Resilience: Physiological And Omics Approaches For Drought And Heat Stress Tolerance In Soybean And Peanut, Jyoti Prasad Kakati

All Dissertations

Soybean and peanut are two major crops globally grown for oil and protein. Climate change-associated factors like drought and increased temperature (heat stress) challenge the global production of soybeans and peanuts. Though the United States is the second-largest producer of soybean and the fourth-largest producer of peanuts, it still faces production constraints associated with drought and heat stresses. In the present study, we have examined the responses of soybean and peanut plants to drought and heat stresses during germination and reproductive phases. We conducted field and controlled environmental studies to elucidate the impact of drought stress on germination and seedling …


Integrating Sensor Development, Risk Assessment, And Community Engagement To Support Environmental Justice In The Rural Community Of El Tiple, Colombia, David Bahamon Pinzon Aug 2023

Integrating Sensor Development, Risk Assessment, And Community Engagement To Support Environmental Justice In The Rural Community Of El Tiple, Colombia, David Bahamon Pinzon

All Dissertations

In Colombia, ethnic communities have traditionally been responsible stewards of natural resources. They recognize the importance of these resources for their livelihood, as well as their ancestral and cultural heritage. El Tiple, a rural Afro-Colombian community, has been affected by the incursion of private corporations that promoted the expansion of sugarcane monocrops in their territory. Since the introduction of the monoculture industry, local freshwater sources have been depleted due to intensive water use for irrigation of the sugarcane crops. Additionally, the intensive usage of agrochemicals has been linked with loss of native flora, damages to family farms, and pollution of …


Laser Inscribed Graphene Aptasensor For Detection Of Apple Stem Pitting Virus, Yifan Tang May 2023

Laser Inscribed Graphene Aptasensor For Detection Of Apple Stem Pitting Virus, Yifan Tang

All Theses

Apple stem pitting virus (ASPV) is a latent RNA virus that could cause significant loss to apple production; early-stage field diagnosis could reduce the economic loss caused by ASPV infection. Biosensor is a promising user-friendly detection tool that could transduce biological or chemical interactions into electric signals. Among various types of biosensors, aptasensor, which use aptamers as recognition elements show potential as a high throughput, in-field test. The goal of this thesis is to develop an electrochemical aptasensor testing system for ASPV detection. The quality control study of laser inscribed graphene (LIG) based working electrode of the biosensor was conducted …


Northern Giant Hornet (Vespa Mandarinia) And Yellow-Legged Hornet (Vespa Velutina), Potential Pests Of Honey Bees, Benjamin Andrew Powell Nov 2020

Northern Giant Hornet (Vespa Mandarinia) And Yellow-Legged Hornet (Vespa Velutina), Potential Pests Of Honey Bees, Benjamin Andrew Powell

Agricultural Education

Exotic hornets present a significant threat to apiculture. Recent introductions of the yellow-legged hornet to Europe and the asian giant hornet to North America have made it critical that regulators, beekeepers and the general public be able to detect and identify these exotic hornets and to understand their biology to minimize the potential impacts to apiculture in South Carolina were they to be introduced.
