If you do not believe in Albrecht's theory, believe what nature is telling us.
Can you relate a beneficial change in plant species to increasing levels of calcium in the soil?
For example the following plants are acting as "index" plants to general soil calcium
levels.
Moss, Sorrel, Sweet Vernal, Capeweed, Fog Grass, Sub clover, Cocksfoot,
Ryegrass*, White clover, Lucerne
LOW CALCIUM SOILS HIGH CALCIUM SOILS |
[ * Ryegrass will also grow in low calcium soils provided the phosphorous levels
are high]
As the succession from weeds to highly productive pasture can be directly related to calcium levels so can
different plants' needs also be related to different calcium levels.
- There is a relationship also between calcium levels and different agricultural crops.
- For example lower calcium levels can favour higher starch producing plants.
- For example higher calcium levels can favour higher protein producing plants
- Albrecht's 60-70% *available Calcium range can be related to the following

The above information is a general guide only and should not be taken
as fact as there are other variables to consider.
Please note that soil pH and soil Calcium levels are two different issues and should not be confused. This topic will be covered in the preceding pages.
What calcium do your plants need?
Calcium levels must meet the requirements of beneficial soil life and plants. Calcium levels are often the dominating cation [+] which influences the chemical [pH], physical and biological nature of the soil.
