Lindsey, Alexander J.; Barker, David J. – Natural Sciences Education, 2023
In spring 2016, a course at Ohio State University (OSU) was introduced to teach advanced agronomic concepts and included the option to prepare students for the Certified Crop Adviser (CCA) exams offered by the American Society of Agronomy. From 2019 to 2021, revisions in instructional methods were implemented that introduced the use of pretests…

Basche, Andrea; Carter, Angie – Natural Sciences Education, 2021
The landowner-tenant relationship is important to the implementation of conservation on agricultural lands. Women own or co-own a significant portion of U.S. farmland yet are underrepresented in conservation research. The next generation of agriculture professionals can benefit from first-hand experience in assisting women landowners and their…

Moorberg, Colby J.; Howe, Sarah; Donnelly, Kevin J.; Min, Doohong – Natural Sciences Education, 2021
The COVID-19 pandemic required changes in college course delivery, which may influence student perceptions of their education. We examined those perceptions among Students of Agronomy, Soil, and Environmental Sciences (SASES). The goals were to determine how changes in education during the COVID-19 pandemic (a) changed student perceptions of…

Lynagh, Peter – Natural Sciences Education, 2013
Hypoxic and anoxic stresses on mesophytes cause a waste of plant productivity. Many phenotypic responses of roots to hypoxia have long been known, and now genotypic and biochemical responses are being elucidated. Hypoxia causes activation of dozens of specific genes that help the plant to survive hypoxia. It is now clear that mesophytes actively…

Thun, Tim Von – Natural Sciences Education, 2013
Arbuscular mycorrhizae fungi (AMF) play a large role in the current understanding of the soil ecosystem. They increase nutrient and water uptake, improve soil structure, and form complex hyphal networks that transfer nutrients between plants within an ecosystem. Factors such as species present, the physiological balance between the plants in the…
