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 …

Roadside Integrated Vegetation Management Bmps: Right Tool For The Right Job, Cheryl Daniels, Davey Resource Group, Inc.
Purdue Road School
Based on a 3-year ODOT IVM research project, lessons learned and techniques for innovative and adaptive IVM for diverse midwestern landscapes will be presented that can increase Indiana DOTs’ efficiency and cost-effectiveness and simultaneously improve worker safety, foster safe highway use, improve roadside aesthetics, and promote environmental stewardship.
Utilizing Gis To Locate Endangered Gravel Hill Prairies Of The Wabash River Valley, Ryan W.R. Schroeder
Utilizing Gis To Locate Endangered Gravel Hill Prairies Of The Wabash River Valley, Ryan W.R. Schroeder
Engagement & Service-Learning Summit
The Gravel Hill Prairies (GHP’s) of the Wabash River Valley are an endangered ecosystem in the state of Indiana and provide optimal growing conditions for a number of state endangered plants. Currently only four remnants are known to exist near Lafayette, IN, found by a previous study conducted in 1980 by Post, Bacone, and Aldrich (Proceedings of the Indiana Academy of Science, 1984, vol. 94: 457-464). These unique ecosystems have been found to occur almost exclusively on soils classified as Rodman Gravelly Loams and Strawn-Rodman complexes which occur predominantly along the outwash terraces of the Wabash River and its tributaries. …

Using Stable Isotopes To Quantify Nitrogen Fates In Container Plants, Sam Raimann, Greg Michalski, Michael V. Mickelbart
Using Stable Isotopes To Quantify Nitrogen Fates In Container Plants, Sam Raimann, Greg Michalski, Michael V. Mickelbart
The Summer Undergraduate Research Fellowship (SURF) Symposium
Currently, in the agriculture field, it is not yet known the accurate amount of Nitrogen in fertilizer that plants take up. This statistic, known as the Nitrogen Use Efficiency is currently known to be within the 30-50% range (Lea-Cox and Ross, 2001). This is very important figure to know and it is a figure that can be improved, and therefore much time, energy, and resources can be saved. This research project will use concepts involving stable isotopes to examine red maple plant material and the soilless media that the plants were grown in. Three different isotope-labelled fertilizer treatments will be …
Evaluating Contaminants Of Emerging Concern In Commercial Biosolid-Based Fertilizers, John Hemmerling, Michael L. Mashtare, Linda S. Lee
Evaluating Contaminants Of Emerging Concern In Commercial Biosolid-Based Fertilizers, John Hemmerling, Michael L. Mashtare, Linda S. Lee
The Summer Undergraduate Research Fellowship (SURF) Symposium
The production and popularity of commercially available biosolid-based fertilizers are increasing because of their economic, environmental, and plant nutrition benefits, particularly in urban and suburban areas. Because biosolid-based fertilizers are derived from waste water treatment plant residuals, we hypothesized that there is the potential for micropollutants to persist in these products. Their presence would be of particular concern due to their potential impact on human and ecological health and risk of bioaccumulation. This study involves quantifying contaminants of emerging concern in three biosolid-based fertilizers, and 2 non-biosolid-based fertilizers, a composted animal manure and an organic compost. Our extraction method employed …
