Sarah A. Uschold – Natural Sciences Education, 2025
Enhanced efficiency nitrogen fertilizers (EENFs) are modified forms of nitrogen fertilizer used to reduce nitrogen loss such as ammonia and nitrous oxide. While these EENFs aim to combat nitrogen loss, environmental impacts, such as moisture, may still influence nitrogen loss through ammonia volatilization. This study aims to further understand…

R. J. Goos; T. M. DeSutter – Natural Sciences Education, 2025
Determining cation exchange capacity (CEC) is a foundational procedure in soil science education. Traditional introductory soil science CEC laboratory methods, both qualitative and quantitative, vary in complexity, resource requirements, and time constraints. Qualitative methods often rely on visual indicators such as cloudiness in solutions or…

Vanesa Santás-Miguel; Manuel Arias-Estévez; Daniel Arenas-Lago – Journal of Chemical Education, 2022
The phytotoxicity of metals is established as a function of soil content; however, their potential negative effect is dependent on the type of soil and fundamentally on the presence of colloids in the soil, mainly of the organic type. For this reason, an experiment on the influence of Zn on the germination of Lepidium sativum L. in two acid soils…

DeSutter, Thomas M.; Derby, Nathan – Natural Sciences Education, 2022
Millions of ha of sodic soils exist around the world and the movement of water through these soils is most directly dictated by the concentration of Na and overall electrical conductivity of the soil, and minerology of the clay. Helping farmers, land managers, crop advisors, and students better understand why water moves or does not move in these…

Cardenas, Alejandra G. – Natural Sciences Education, 2023
As our population continues to grow, the demand of a more efficient agriculture system heightens. We work to produce the highest yield possible to cover demands. Are we compromising our water quality for mass food production? In past years, the West Coast growers had been facing increasing struggles to farm with their allotted water often turning…

Mara R. Fink; Tyler Z. Sodia; Kevin J. Cash – Journal of Microbiology & Biology Education, 2024
Winogradsky columns were invented by Sergei Winogradsky in the 1880s and have commonly been used as a microbiology classroom learning tool in K-12 and collegiate education. However, they can be challenging to examine with microscopy. We scaled down Winogradsky columns into nuclear magnetic resonance (NMR) tubes and replaced the natural sediment…

Barron, Christopher – Natural Sciences Education, 2022
Agriculture in much of Uganda is struggling, especially in Soroti District. Many of the issues are linked to the poor soils that are present in this region. Farmers in Soroti District will need to adopt various soil conservation techniques and practices to improve their soils over time and increase production.

Gabor, Donna Hembra – Journal of Science Learning, 2023
Experimentation is a contributing factor to the interest and meaningful learning of Science. In Geology and Earth Science, the effects of soil textures, settlements, and water-holding capacity are parameters for landslides in Barotac Viejo and other flooded areas. Landslides are triggered during heavy rainstorms, causing severe property damage and…

Diego Corrochano; Daniel Zuazagoitia; Marcia Eugenio-Gozalbo; Lidón Monferrer; Inés Ortega-Cubero; Aritz Ruiz-González; Lourdes Aragón – Journal of Biological Education, 2025
Pre-service teachers' mental models of the nature of soil were investigated in a sample of 181 students from four different Spanish universities, using three different methodological approaches: a phenomenographic analysis of definitions, a categorisation of labelled-drawings and the analysis of answers to a questionnaire consisting of both open-…

Jamie Loizzo; Sadie Hundemer; Gabriel Spandau; Samuel Smidt; Alice Akers; Jehangir Bhadha; Young Gu Her – International Journal of Science Education, Part B: Communication and Public Engagement, 2025
Scientists' social responsibilities can include ethical research conduct, transparent public communication, and accountability to society to develop solutions. Scientists describe mounting pressure to advocate for their work amidst political, financial, religious, misinformation, lack of public trust, and other influences. The purpose of this…

Joseph Meinert; Kerry Clark; Stephen Anderson – Natural Sciences Education, 2025
One-quarter of households in the state of Missouri are connected to an onsite sewage treatment system. These systems are necessary due to the risks human effluent poses to public health and our states' aquifers and waterways. For these systems to function correctly, a thorough and accurate evaluation of the soils and landforms onsite must be…

Robert L. Mahler – Natural Sciences Education, 2023
Enrollment in soil science courses at land grant universities in the United States has been stagnant or declining for the last 20 years and this trend is expected to continue in the foreseeable future. The purpose of this paper is to evaluate a newly developed course in drinking water and human health (DWHH) that was designed to widen soil science…

Bethany Wolters; Hannah Angel; Isaac Lepcha – Natural Sciences Education, 2023
During the COVID-19 pandemic, preexisting soil science laboratories were redesigned for self-guided learning (SGL). The SGL laboratories occurred on-campus during the fall 2020 semester in two introductory soil science courses at the University of Tennessee at Martin and Virginia Polytechnic Institute and State University. Students carried out the…
