Enrollment by students in degree programs other than traditional horticulture, agronomy, and soil science has increased in basic plant and soil science courses. In order to broaden the appeal of these courses to students from majors other than agriculture, we developed a hands-on laboratory exercise relating the basic concepts of a soil energy…

In order to keep the land productive, a good conservation program is imperative. The primary purpose of soil and water conservation is to prevent soil erosion and heal its scars. This handbook explains the causes, processes, and consequences of soil erosion and depletion, and describes major soil- and water-conservation measures. This book was…

Evaporative cooling systems are commonly used in controlled environment plant and animal production. These cooling systems operate based on well defined psychrometric principles. However, students often experience considerable difficulty in learning these principles when they are taught in an abstract, verbal manner. This article describes an…

Environmental Sciences Technology T272 is a course with a laboratory addressing problems in soil and water quality and organic wastes utilization to serve students from associate degree programs in laboratory science and environmental resources management at a 2-year technical college. Goals are to build basic lab skills and understand the role…

Describes a laboratory exercise for undergraduate science students in which they evaluate soil samples for various parameters related to suitability for crop production and capability for retention of contaminants. (Contains 18 references.) (WRM)

The advantages and disadvantages of poster sessions vs. oral talks are reviewed. Front-end and secondary planning, materials, and follow-up needed for poster sessions are outlined. An example session and a check list are included. (Author/CW)

Presented is a successfully implemented active learning project and results of a survey to assess the success of the project. Materials and methods are discussed, and an example of one project is provided. (Author/CW)

Described is a technique for taking a large monolith for the purpose of teaching soil structure. Materials and procedures are detailed. A survey of 93 students indicated that the larger monolith was preferred over the commonly used narrow ones. (CW)

Compared are the estimates of students and professional field soil scientists. Results indicate that with three weeks of practice and the availability of good reference samples, students can attain a level of proficiency comparable to professional soil scientists. Suggestions for grading evaluations are provided. (Author/CW)

A peer review process similar to that used by scientific journals which can be applied to class work is presented. Stressed is the advantage of using peer review when writing skills are a priority but instructor time is limited. Guidelines and examples of comments are provided. (CW)

Describes how teachers can improve introductory soil science courses by applying concepts taught in the classroom to actual field situations. Presents a specific example of a field exercise designed to illustrate soil properties and processes with respect to their environmental settings. (11 references) (Author/MCO)
