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 soil pH is important because it affects the availability of nutrients in the soil. Most nutrients needed by plants are most available in the soil at a pH between 6 .0 to 7.5.

With municipal watering restrictions in effect and heat stress accumulating in root zones, Yieryi is encouraging home growers ...

Soil pH is measured on a scale of 0 to 14. The lower the pH value is on the scale, the more acidic soils are, while higher soil pH values correspond to more alkaline conditions. When to Raise pH ...

"To noticeably shift the flower colour, gardeners typically need to adjust the soil pH more deliberately using soil ...

Soil pH is a scale of acidity-alkalinity that ranges from 0 to 14, with the most common levels found between 4 and 8. Seven is neutral. Readings above 7 show alkalinity; readings below, acidity.

A pH of 7 is neutral; below 7 is acidic, and above 7 is alkaline. Most plants including flowers, vegetables, trees and shrubs grow best when the soil pH ranges from 5.8 to 7.0.

Depending on soil conditions about 30 to 100 pounds of limestone is commonly added to 1,000 square feet of garden. Because wood ash particles are much smaller than limestone particles, only about ...

Irises can be dramatic when they're not exposed to the perfect conditions, but this simple trick might be all that your ...

A pH test is part of every soil test we found, and you can also buy a pH test separately, from soil-test-kit manufacturers or your local hardware store. (We did not test these individual options.) ...
