This method gives a reliable, efficient, and practical way of measuring the soil nutrients nitrogen, phosphorus and iron. The kit also measures pH and texture. Another advancement is available with the potassium test, which uses a turbidity tube calibrated to read directly in pounds per acre for low to high values. Analyses of calcium and magnesium are conducted with Direct Reading Titrators. The LaMotte Turf Lab kit can be used efficiently and accurately in the field and in the lab.
