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…

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…

Background/purpose: Teaching complex concepts in STEM areas has led education researchers to innovate in teaching models. In this report, we present a study of engineering teaching on the geotechnical structure of Mexico City, which is characterized by highly compressible clayey soils and significant seismic activity, which, for the discipline,…

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…

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-…

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…

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…

Undergraduate institutions serve as stepping stones to students' careers. Teaching and learning in science classrooms require quality and integrated teaching-research learning experiences that prepare students to advance their careers. Using publicly available data sets and open-access data analyses software can be impactful for engaging students…

We implemented research-based learning (RBL) as an alternative to traditional frontal classroom lectures and laboratory sessions to impart knowledge on the emerging topic of microplastics in soil to students. The RBL module aimed at studying how microplastics (MPs) affect soil processes. We designed low-cost, small-scale and simple experiments for…

Purpose: Declining soil fertility is worrying in sub-Saharan Africa. Various technologies serve to mitigate or rebuild soil fertility, but uptake by farmers, especially smallholders, is low. The study addresses this adoption problem in a novel way, assessing empirically many factors from various domains (economic, socio-demographic, individual,…

To create opportunities for meaningful applications of data science for diverse students, we developed and implemented an online learning module focused on engaging students at a Hispanic Serving Institution (HSI) in an analysis of authentic soil data. Development of the module occurred over three design iterations involving interviews with 10…

Laboratory experience is an integral part of the undergraduate curriculum in most engineering courses. When physical learning is not feasible, and when the demand cannot be met through actual hands-on laboratory sessions, as has been during the COVID-19 pandemic, virtual laboratory courses can be considered as an alternative education medium. This…

Current models of best practice in science education advocate for students to learn science by engaging in applied contexts that integrate the various science disciplines. Permaculture offers one such integrated context for elementary science. Although permaculture is relatively new in PK-12 education, the broader practice of school gardening has…

This academic inquiry examines the efficacy of virtual reality (VR)-based pedagogy for higher learning, specifically analyzing immersive digital instruction for rural agriculture undergraduates studying soil science in Colombia. The investigation tests two hypotheses: first, simulated learning situations improve academic achievement and student…

Flexible, accessible course delivery modalities with enhanced virtual components are a common component of post-pandemic university-level goals and policies across the United States. From the Spring 2023 to Spring 2024 academic semesters, curriculum overhaul facilitated a more flexible modality structure in the introductory-level Crop Science…
