If you're just starting to learn about agriculture, biology, or human environmental sciences, it can be a bit daunting. There are hundreds of online resources dealing with such matters, and separating the wheat from the chaff can be taxing and time-consuming. Valerie Perry and Jo Staggs-Neel at the University of Kentucky Library's Agricultural Information Center have created these three excellent research guides to the aforementioned subjects. The guides contain seven or eight separate subsections, including "Electronic Resources", "Best Databases", and "Frequently Cited Journals". Each guide also contains a "New Resource" area which profiles a newly added resource that complements the existing set of resources. A number of the links lead to resources that require a password or subscription, but there are enough here with open access to pique the interest of persons new to the field. Overall, it's a good way to get a basic grounding in the important online and offline resources in these three scholarly subjects.
