Economical Test Kits for Soil Education and Fertility
These Soil Test Kits provide rapid test procedures for quick determinations of pH, nitrogen, phosphorus and potassium. Diagrammed instructions and laminated color charts are used to measure each concentration. Each kit contains "A Study of Soil Science" and the "LaMOTTE Soil Handbook" to provide in-depth background information and data for interpretation of test results.
The Model EM provides 60 tests for pH, 30 for nitrogen, 40 for phosphorus and 30 for potassium. Model EL provides 30 tests for pH, 15 for nitrogen, 20 for phosphorus and 30 for potassium. Range: pH 4.0-8.0. All other elements from Low-High.
