Nutrient Management Planning
The Importance of Soil pH
(2013-07-29) In the soil pH scale of 1 to 14, a pH of 7 is neutral and a pH of 5 is considered very acidic. A soil pH of 6.0 to 6.5 is usually considered to be a good indicator of a productive field. PEI soils are naturally acidic, this is because of the material from which our soil was formed and our relatively high rainfall. The use of commercial fertilizer also has a considerable effect on lowering soil pH.
The use of agricultural lime is the most effective way to increase soil pH. As the calcium and magnesium in the aglime becomes part of the soil solution the soil pH increases and provides the following crop production benefits.
The best way to find out if your land requires lime is to have your soil analyzed. Soil testing will be our fall topic.
