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 and meaningful measure of
soil calcium he developed a sodium acetate extraction 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 our customers at no charge. There is a $10.00 per soil sample charge to non customers.
This charge is refundable on the first order.
