Soil pH Meter

About soil pH meter: keeping your soil balanced

pH

In soil, pH extremes limit biological activity, humus formation, and plant growth. Frequent monitoring is essential, as soil pH changes rapidly during fertilization, irrigation, and even the phases of the moon. Effective pH monitoring of spray solutions will maximize pesticide effectiveness and nutrient uptake in foliar feeds.

Reference solutions

Reference solutions are not included with most meters, although they are necessary to calibrate your meter. For pH, the 7.0 solution is the solution to use for primary calibration. If accurate readings below pH 6.0 are consistently needed, the 4.0 solution is also recommended. For best calibration and accuracy, use both the 7.0 and 4.0 reference solutions.
