Best Soil pH Tester

Soil Health
4 min read

Without the right soil pH, you are wasting between 20% and 70% of your lawn fertilizer nutrients.  Take advantage of the best soil pH tester from Jonathan Green and MAG-I-CAL® to adjust the pH and optimize your lawn’s growth and color.

Jonathan Green has been growing great looking lawns since 1881.  We supply genetically superior cool season grass seed and other lawn and soil care products to commercial sod growers and independent retailers in all areas of the United States where cool season lawn grasses – Kentucky Bluegrass, Tall Fescue, Perennial Ryegrass and Fine Fescues – are grown.

Importance of Soil pH

The “p” in pH stands for “potential. The “H” stands for hydrogen. It’s a mathematic symbol that represents the logarithmic scale of the hydrogen ion.

On a scale of 1 to 14, a pH of 1 is very acidic and a pH of 14 is very alkaline (or basic), while a pH reading of 7 is neutral.  Lawns grow best in a soil that is slightly acidic to neutral (between 6.2 and a 7.0 on the pH scale).

Soil pH is a very important factor in lawn health – if the soil is too acidic or too alkaline, your grass will be unable to absorb nutrients properly. Highly acidic soil can also damage grass plant roots.

Soil Testing

A soil test kit will let you know if your soil has a low or high pH.

Jonathan Green’s easy-to-use Soil pH Test Kit for Lawns determines pH levels in just five minutes. The kit includes one test tube, one capsule of powder, and one pH range color chart to help you identify the results.

It is important to use either distilled water or rainwater when using this test kit in order to get accurate pH readings. Tap water has been pH-adjusted by municipal water authorities and will affect the reading.

Another great option is Jonathan Green’s Pro pH & Moisture Soil Tester, which accurately measures soil pH and moisture levels to within 0.2 pH and a 10% moisture level in just two minutes. This high-quality professional tool is used by sod growers, golf course superintendents, sports field managers, and landscapers to determine the right time to add fertilizer and lime.

How to Change the Soil pH

If the soil pH reading is not between 6.2 and 7.0, use Jonathan Green MAG-I-CAL® or MAG-I-CAL® Plus to rapidly balance the pH and help the lawn grow greener and healthier.

  • If severely acidic (pH of 3.0 to 5.0) – Spread three bags of MAG-I-CAL® on the lawn
  • If very acidic (pH of 5.0 to 6.0) – Spread two bags of MAG-I-CAL® on the lawn
  • If slightly acidic (pH of 6.0 to 7.0) – Spread one bag of MAG-I-CAL or MAG-I-CAL Plus
