IN TRO DUC TION
The importance of phosphorus to plant life has been outlined in the
accompanying handbook, A Study of Soil Science. In this exercise the
student will:
A. Study the color reaction of High Fertility Soil (5724) which contains
a high potassium content.
B. Test a soil sample of unknown value to determine if potassium is
present and if so, determine the relative level of potassium that is
contained in the sample. The soil sample used may be furnished by
the instructor, or may be collected and prepared by the student.
