Synopsis

Synopsis

The following sequence of 10 most important topics, with the number of schools teaching each topic, was stressed: texture—65, moisture—60, soil reaction (pH) and limestone—58, rocks and minerals—56, structure-55, profile study-54, classification and survey—54, soil testing—51, microorganisms and organic matter—50, and fertilizers—47. Almost two-thirds of the instructors provided at least as many hours in the laboratory as in the lecture. General chemistry was the most common prerequisite for the introductory soil science courses.
