The pH range of soil typically falls between 4.5 and 8.5.
Soil pH is a measure of its acidity or alkalinity. A pH of 7 is considered neutral. A pH below 7 is acidic, and a pH above 7 is alkaline or basic.
The pH of soil is influenced by a variety of factors, including:
* **Parent material:** The type of rock from which the soil is formed.
* **Climate:** Rainfall and temperature can affect soil pH.
* **Organic matter:** Decomposed plant and animal material can make soil more acidic.
* **Fertilizers:** Some fertilizers can make soil more acidic or alkaline.The pH of soil is important because it affects the availability of nutrients to plants. Most plants prefer a soil pH between 6.0 and 7.0.
Soil that is too acidic can make it difficult for plants to absorb nutrients like calcium, magnesium, and phosphorus. Soil that is too alkaline can make it difficult for plants to absorb nutrients like iron, manganese, and zinc.
To determine the pH of your soil, you can use a soil test kit, which is available at most garden centers.
You can adjust the pH of your soil by adding amendments like lime (to raise pH) or sulfur (to lower pH).
