These online courses at Open University are organized by linked and labeled sections and sub-sections in outline form. The course outline remains in view in a left sidebar, while the main content may be accessed and browsed on the rest of the page. How Do We Adapt Agriculture to Climate Change? discusses such topics as greenhouse gases, food security, and industrial agriculture, as well as a call for structural shifts in agriculture to account for climate change. A link is provided to a printable version that displays the full content of the course on one page. Social Issues and GM Crops addresses effects, implications, and ethical questions regarding genetically modified (GM) food and crops. Students will learn about GM food safety assessment, the experiments and findings of scientist Arpad Pusztai, and food production considerations, among other subjects. This class is also viewable in printable form.
Rather than college courses per se, these resources are written expositions that were researched, composed, or made with significant contributions by Purdue University faculty members. The articles listed here are only a few in a catalog of such resources with categories like agribusiness and farms, crops, and livestock. Agricultural Biotechnology gives an overview and definition of biotechnology, along with a discussion of its potential effects, uses, and implications in the contexts of food and agriculture. The document is viewable online but not available for download. Pesticides and the Environment addresses ways the interactions between pesticides and environmental factors influence the effect pesticides have on the ecosystems to which they are introduced. This article may be viewed online but is also not downloadable. Weed Control in No-Tillage Systems outlines strategies for establishing and maintaining weed control, incorporating issues such as weed identification, herbicide application timing, and postemergence procedures. This paper may be downloaded as a PDF file and includes a chart delineating weed types and the recommended herbicides for controlling them among different kinds of crops.
The University of Florida
These free courses are accessible online in audio format and include corresponding PowerPoint slides. Though each course may play as a single audio file, a list of the content areas is also viewable in a sidebar, so students may click on a link any time to go to a particular topic. Irrigation Components teaches students about controllers, electrical valves, backflow prevention implements, and sprinklers, among other subjects. In Soil Sampling and Testing, students receive instruction about soil nutrients, how to interpret soil test results, and fertilizer suggestions. Information on the materials and steps required to obtain a soil sample is also provided.
University of Nottingham
- Orchestrating Cell Separation in Plants: What Are the Risks and Benefits?
- Sustainability: The Geography Perspective
These University of Nottingham courses are available in various configurations of video, text, and audio formats. All files are accessible online or available for download.
