A Fork In The Road: Uncovering The Impact Of Industrial Animal Agriculture On The Physical Health Of Communities Of Color, Mariana Zepeda

Population Health Research Brief Series

Nearly all (99%) farmed animals in the U.S. come from Concentrated Animal Feeding Operations (CAFOs). CAFOs are industrial agriculture facilities defined by the U.S. Environmental Protection Agency (EPA) as operations where animals are raised in confinement and meet animal size and waste material thresholds. Communities located near CAFOs, which tend to have high shares of low-income and racial/ethnic minority residents, are at risk of exposure to CAFO-related air and water pollutants. This brief summarizes the health risks for communities located near CAFOs. Additionally, it calls for government regulations that improve transparency, management, and consumer empowerment.

Department of Horticulture & Landscape Architecture Faculty Publications

Black soldier fly larvae (Hermetia illucens; BSFL) composting is biotechnology used for organic waste management and an alternative to traditional composting. We designed a two-phase experiment to evaluate the effect of BSFL composting on the emergence of the following six weed species: barnyardgrass (Echinochloa crus-galli), common ragweed (Ambrosia artemisiifolia), giant foxtail (Setaria faberi), ivyleaf morningglory (Ipomoea hederacea), redroot pigweed (Amaranthus retroflexus), and velvetleaf (Abutilon theophrasti). The first experiment phase was in the laboratory (laboratory composting phase), which consisted of 100 seeds of each weed species subjected to five composting treatments [two controls (nontreated and standard Gainesville diet alone) and three …

Investigating The Accuracy And Comparability Of Various Lime Prediction Methods For Irish Grassland Mineral Soils, F. Mackessy, E. Mccarthy, E. Broderick, B. O'Donnell, Patrick Quille

Publications

Soil pH is a foundational element of agronomy, profoundly influencing biological, chemical and physical soil processes. Adjusting soil pH is a paramount factor for enhancing soil health and productivity with far-reaching environmental benefits. Over time soil naturally tends towards acidity, a process expedited by intensive agriculture practices. To determine the extent of necessary pH corrections, precise soil pH testing is imperative. Various methods including buffer systems, titrations, lime incubations and algorithms considering soil texture are used to assess a soil's lime requirement and each method carries distinct advantages and disadvantages. The Shoemaker–McLean–Pratt (SMP) buffer method is extensively used in Ireland …

Graduate Industrial Research Symposium

In 2015, the corn-infecting pathogen Phyllachora maydis (causal agent of tar spot disease) was reported for the first time in the United States. The disease has since spread across the US, causing major yield losses. In 2021 alone, 5.88 million metric tons (231.3 million bushels) of US corn yield were lost to this disease, costing an estimated US$1.25 billion. Though fungicides can protect against these agroeconomic losses, application timing can be difficult to optimize because our understanding of tar spot dynamics is still evolving. The current view is that tar spot typically develops bottom-up through a repeating infection cycle. Because …

Evaluating The Environmental Impacts Of U.S. Historical Oil Spill Incidents, Yiming Liu, Hua Cai

Graduate Industrial Research Symposium

Exposure to risks associated with the production and usage of products, particularly oil, poses significant threats to both ecological systems and human health. Notable examples include the Gulf War Oil Spill (1991) and the Deepwater Horizon Oil Spill (2010). However, numerous smaller-scale oil spills, which collectively contribute to substantial oil releases, often remain overlooked. To fill this gap, our study first developed a detailed oil spill incidents database, covering 1967 to 2023. We quantified the released amount (RA) of oil spills recorded by the National Oceanic and Atmospheric Administration (NOAA). Subsequently, we utilized life cycle impact indicators in ReCiPe to …

Anti- Transpirants Impact On Pepper Cultivated Under Different Drought Stress Levels, Ola Alnaddaf, Elien Abo Saeb, Ayman Abo Assi

Jerash for Research and Studies Journal مجلة جرش للبحوث والدراسات

Drought is one of the most limiting factors for agricultural productivity worldwide (Hamdi et al., 2020). Drought stress can be simply defined as a shortage of water that causes significant changes in plant morphology, physiology, and biochemistry (Liang et al., 2020), and the most environmental stress that affect both crop production and quality (Biareh et al., 2022). Approximately, 95-98% of the water absorbed by the plant is lost via transpiration (Singh et al., 2021), so that reducing the transpiration rate could be considered as an important strategy for combating with drought conditions. This could be achieved by using compounds called …

Managing Saline And Sodic Soils And Irrigation Water, Burdette Barker, Grant Cardon, Matt Yost, Melanie Stock, Earl Creech, Jody Gale

All Current Publications

Salt is an important factor in plant and soil management. Excessive salt concentrations in soil can cause water to be less available to plants because of the osmotic forces of salt in the soil water. Excessive concentrations of different ions can also be toxic to plants. In agricultural soils and irrigation water, salts are typically described in two ways: (1) total salt concentration or salinity, and (2) sodicity, or the concentration of sodium relative to other cations (positively charged atoms or compounds). Understanding the effect of both total salinity and sodicity on plants and soils, along with management and reclamation …
