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 ...

Contour plot of soil pH across the study site, contour lines represent changes in soil pH across the study site to the nearest 0.5 pH unit. Crosses mark locations of sampled soil cores from the ...

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 ...

Adding organic matter to the soil improves its structure and nutrient content. Compost, leaf mold, or well-rotted manure are ...

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 ...

The Hslgove 2-in-1 soil tester will measure your soil's pH and moisture levels in minutes. As a rule of thumb, don't add wood ash to soil with a pH near 7.0 unless you're growing plants that ...

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 ...

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.
