ACID SOIL

pH & Fertilizer Soil Analyzer

Soil pH is referred to as the acidity of the soil and is measured by the number of Hydrogen ions present in the soil solution. When the soil pH is too low(acid) or high(alkaline), nutrients present in the soil become locked-up or unavailable. Correcting the pH has the same effect as applying fertilizer since it releases plant nutrients already present.

Acid soils have a pH of 7.0 or lower when tested. And testing is important when attempting to do any adjustments to the soil's pH. Acid soil, you will find are mainly eastern states of the U.S.A.

When the soil is too acid problems may occur like interveinal chlorosis and making the essential nutrients unavailable to the plants. And you will have to be very selective about the plants you use.

Easy-to-use test strips reliably analyze pH, nitrogen, phosphorus, potassium. Click here.

LIST OF SOIL pH

4.0 to 5.5 is strongly acid

5.5 to 6.0 is medium acid

6.0 to 6.5 is slightly acid

6.5 to 7.0 is very slight acid

7.0 to 7.5 is very slight alkaline

7.5 to 8.0 is slightly alkaline

8.0 to 8.5 is medium alkaline

8.5 to 10.0 is strongly alkaline

On a scale of 1 to 14 is the range for the level of acidity and alkalinity with 1 being highest acidity and 14 being the highest alkalinity. Examples of each are:

vinegar is a mild acid

battery acid is very acid

baking soda is a mild base(alkaline)

Drano is a stong alkaline

Water that is purified is neutral(pH 7.0)

The uptake of nutrients from the soil to the plants relies on the pH of the soil and the nutrient being transferred to the plant. Some nutrients do better at acid levels and some do better at alkaline levels. A reason, I believe, to use organic materials in gardening. Organic methods can adjust the intake to suit the plant.
