Soil pH or soil reaction is an indication of the acidity or alkalinity of soil and is measured in pH units. Soil pH is defined as the negative logarithm of the hydrogen ion concentration. The pH scale ...

The pH scale goes from 0 to 14 with pH 7 as the neutral point. As the amount of hydrogen ions in the soil increases the soil pH decreases thus becoming more acidic. From pH 7 to 0 the soil is ...

'If you need to make your soil more acidic and lower the pH, you can try adding organic matter such as pine needles or ...

Soil pH levels range from 0 to 14, with 7 being neutral. Levels below 7 are acidic, and those above are alkaline. Neutral soils are less common than either extreme and tend to cluster at the ...

Most plants thrive in soils with a slightly acidic to neutral pH of around 6.0 to 7.0. If you’re struggling with overly acidic soil, knowing how to raise pH in soil closer to that neutral range ...

Blue hydrangeas thrive in soil with a pH range of 4.0-5.0, while artichokes prefer a pH range of 6.5-7.0. If your soil is too alkaline, you can add organic material such as a compost enriched with ...

The team's results show that extensive overuse has caused the pH of soil across China to drop by roughly 0.5, with some soils reaching a pH of 5.07 (nearly neutral soils of pH 6-7 are optimal for ...

Proper pH level of the soil is also key to supporting a wide range of beneficial microorganisms such as bacteria, fungi, protozoa and nematodes, which are present in healthy soil.

Coffee grounds have a nearly neutral pH of 6.5- 6.8 (neutral is 7), but brewed coffee reportedly has a lower pH, ranging around 5.2 to 6.9 depending on the type of coffee and its strength.

Certain plants require specific soil pH ranges to do well, ... 14 being alkaline and 7 being neutral, or balanced. You don’t need to be a chemist to check your soil pH.
