Students experiment with easy-to-use soil test procedures to determine soil pH, nitrogen, phosphorus and potassium concentrations. Chemicals and materials are provided so each test can be performed 50 times. Each test is separately packaged so several teams of students can work simultaneously. Each kit contains materials and instructions to conduct the four tests mentioned above, a soil texture and classification unit, soil sampling tube, soil sample bags and the book A Study of Soil Science. Materials are conveniently packaged in a polypropylene case.
