What is Acidic Soil?

Acidic soil is defined as the pH level below 7. The closer you get to an acidic value, the more humus in your soil, and it becomes less nutrient-rich. Acidic soil is made up of a high percentage of organic matter, and many different things will affect the pH in your soil.

1 to 14 is the scale used to measure the acidity of soil and other things, too. Everything above is thought to be alkaline. Most plants in the garden like a pH between 6 and 7.5. People who want their garden plants to grow well need a pH level between 6 and 7.5. Between 6 to 7.5 soil ph, phosphorus in the soil is soluble, which means it can be absorbed by plant roots because it dissolves in water. All plants need phosphorus, one of the three macronutrients they need. In the NPK ratios you see on packaged fertilizers, phosphorus is the middle number. It helps the plant bloom and set fruit.

What Causes the Ground to Become Acidic?

Most wooded areas have acidic soil, as do many parts. As organic matter breaks down, the ground where this decomposition occurs tends to become acidic by itself.

However, there are a variety of other causes that might contribute to soil acidification, including:

  • The use of chemical fertilizers is not good for the earth.
  • When it rains, calcium and magnesium are washed away from the ground.
