Geographic Soils Information (Chapter 19) Notes
Geographic Soils Information (Chapter 19) Notes
Did you know .... Did you know that almost every acre of soils in the United States has been mapped and characterized? Chapter 19 highlights graphical information from soils and how we can utilize it to better manage our resources.
Lecture content notes are accompanied by videos listed below the notes in each submodule (e.g. Geographic Soils Information Chapter 19) Videos A and B). Print or download lecture notes then view videos in succession alongside lecture content and add additional notes from each video. The start of each video is noted in parenthesis (e.g. Content for Video A) within each lecture note set and contains lecture content through the note for the next video (e.g. Content for Video B).
Figures and tables unless specifically referenced are from the course text, Nature and Property of Soils, 14th Edition, Brady and Weil.
