Despite the growing importance of agricultural microbiology at the applied, productive and ecological levels, undergraduate degrees in Agronomy generally do not feature much microbiological experimentation. To address this deficiency, we have designed an experimental programme that evaluates the potential of plant growth-promoting rhizobacteria…

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,…

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…

International Extension experiences can provide valuable outcomes to clientele. Careful planning is necessary to maximize the benefits to participants and the potential impacts of the tour. International agricultural sciences students can benefit from participating in these tours and greatly add to their success. In this article, we describe the…

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…

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…

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…

Purpose: There is inconsistency in the design, understanding, implementation and monitoring of soil health programmes. Despite mounting scientific evidence for the credibility of certain soil health indicators, an increase in the reporting of programme benefits, and progress in communicating these benefits, many farmers remain hesitant to…

Understanding plant breeding as well as procedures and issues of seed companies are skills students studying agronomy need to acquire. Simulation games can be effective teaching tools in developing higher-order thinking skills of students. The "Fantasy Seed Company" game was developed to create motivated learners by allowing students to run a mock…

Some soil and crop science university programs undergo curricula revision to maintain relevancy with their profession and/or to attract the best students to such programs. The Department of Soil and Crop Sciences at Texas A&M University completed a thorough data gathering process as part of its revision of the undergraduate curriculum and…

Copper fungicides and bactericides are often used in tomato cultivation and can cause toxic Cu levels in soils. In order to combat this, organic matter can be applied to induce chelation reactions and form a soluble complex by which much of the Cu can leach out of the soil profile or be taken up safely by plants. Organic acids such as citric,…

It is difficult to demonstrate the soil water retention relationship and related concepts because the specialized equipment required for performing these measurements is unavailable in most classrooms. This article outlines a low-cost, easily visualized method by which these concepts can be demonstrated in most any classroom. Columns (62.5 cm…

Purpose: This article investigates the extent of multiple knowledges among smallholders and connected non-farm agents around Mount Elgon in Kenya and Uganda in order to build the communicative competence needed to scale up conservation agriculture production systems (CAPS). Design/methodology/approach: Our methodological approach examines local…

Integrating livestock into a cropping system by allowing ruminant animals to graze cover crops may yield economic and environmental benefits. The effects of grazing on soil physical properties, soil organic matter, nitrogen cycling and agricultural production are presented in this literature review. The review found that grazing cover crops…

Opportunities for farmers to participate in greenhouse gas (GHG) credit markets require that growers, students, extension educators, offset aggregators, and other stakeholders understand the impact of agricultural practices on GHG emissions. The Farming Systems Greenhouse Gas Emissions Calculator, a web-based tool linked to the SOCRATES soil…
