Abstract	Because soils provide water, minerals, and a medium to anchor the roots of plants, measuring the basic physical/chemical components of soils is important to maintaining healthy garden plants and agricultural crops. Historically, soil analysis has been practiced to determine fertilizer and lime applications, soil fertility, and soil improvement practices. However, since it can be expensive to test soils through soil analysis labs, the authors wanted to determine if commercially available soil test kits were accurate enough to use in the classroom. Many of these test kits are inexpensive and would be ideal for use by teachers with a limited budget. The purpose of this paper is to compare soil test results using a variety of commercially available test kits with results from a soil testing laboratory. Recommendations for basic soil testing in the classroom are given. (Contains 4 tables.) (ERIC).
