Soils Laboratory Manual
Moorberg and Crouse, 2017
The Soils Laboratory Manual, K-State Edition is designed for students in undergraduate, introductory soil science courses, and highlights the many aspects of soil science, including: soil genesis and classification, soil physical properties, soil-water interaction, soil biology, soil chemistry, and soil fertility. The lab manual includes 15 different laboratories, each one starting with an introduction and pre-lab assignment, followed by in-lab activities, and complimented by post-lab assignment. In-lab activities involve field trips, experiments, observation stations, or problem sets. Post-lab assignments include online quizzes, problem sets, or laboratory summary reports.

Soil and Water Conservation: An Annotated Bibliography
Moorberg and Others, 2019
Soil and Water Conservation: An Annotated Bibliography highlights freely-available online resources covering various aspects of soil and water conservation, and is designed to be a resource for conservation students and practitioners. The thirteen chapters cover history and fundamentals, conservation practices, conservation implementation, and careers. Cited resources are generally concise, easily read, and meant for general audiences. Annotations and images are used to provide context for each resource. Many contributors made Soil and Water Conservation: An Annotated Bibliography possible through their assistance with technical edits, outline development, identifying resources, or writing annotations. Chapter authors are experts and practitioners of soil and water conservation, or students of soil and water conservation who worked under the supervision of the editor, Colby Moorberg. The annotated bibliography is used as the primary text for Kansas State University’s AGRON 635 – Soil and Water Conservation, which is taught by Moorberg.
