Innovative way to use silicic acid to improve growth and chemical composition of cucumber transplant

Do You know the silicic acid methodology to increase the growth and chemical composition of cucumber transplants?

I have tried to grow cucumber transplants using followed innovative treatment:

There were two treatments: 1. stabilized silicic acid treatment; 2. control.

Cucumber seeds were sown on 21 of March 2014 in plastic trays and seedlings were grown in a heated glassgreenhouse. Seedlings were transplanted once into individual pot (9 cm diameter), (10 of April 2014). Seedlings and transplants were grown in Novarbo B2 Organic Biolan substrate (lime content 6 kg/m3, fertilizer content 1.0 kg/m3, fertilizer N-P-K 12-6-22, pH neutral) for organic cultivation. Silicic acid treatment was carried through as followed: First spray, when plants were growing and when 1 real leaf was present (7.04.14); second spray was 2 weeks after spray 1 (21.04.14); third spray as 2 weeks after spray 2 (05.05.14). Sprays were followed: First spray: 1ml silicic acid was solved in 0,5 liter clean (demineralized water, pH neutral) water; second spray: 2 ml silicic acid was solved in 1 liters clean (demineralized water, pH neutral) water; third spray: 2 ml silicic acid was solved in 1 liter (demineralized water, pH neutral) water. pH of spray solution was 5,5. Control plants were untreated.


Cucumber transplants were taller and stem diameter was greater in silicic acid treatment compared to control. The content of N, P and Mg were higher in Si treated plants.
