Calcium in the Soil

High calcium levels in the soil:

  • Help correct soil acidity
  • Help improve soil structure
  • Help the soil overcome the harmful or toxic effects of excess soluble salts of magnesium, sodium and potassium
  • Help provide proper conditions for microbiological growth
  • Help regulate nutrient absorption into the plants.

Calcium is non poisonous, essential to life and of all the mineral elements necessary for plant growth, calcium is the only one responsible for so many different functions in the soil surrounding the plant root. An alkaline metal of Group IIA on the periodic chart, calcium is the fifth most abundant element in the earth's crust and is widely distributed in nature. The electronic structure of the calcium cation makes it ideal for plant growth.

One of our founders and the developer of Growers Mineral Solutions (GMS), Dr. V. A. Tiedjens studied and verified early basic research from around the world. One was the work conducted by K. K. Gedroiz, who found that "After the practically complete replacement from the soil of all exchangeable calcium, the plants required for their development the introduction into the soil of calcium fertilization, without which they would not grow at all."


Dr. Tiedjens believed that the industry's standard pH test was not a true measure of calcium availability. Consequently, he abandoned the pH test, and in his search for a more accurate measure of soil calcium, he developed his own test. This he coordinated with the results of yield trials to fine tune and give reliability to his testing procedure.

Using basic scientific research and his years of field research, Dr. Tiedjens was able to determine the soil calcium levels necessary for maximum plant productivity at the least expense. Testing for the amount of available calcium in various soils was, and continues to be, an important service Growers provides to customers at no charge.
