Calcium nitrate (Norway, Portugal)
The only source of water-soluble calcium for hydroponic systems, and an essential component of a balanced soil fertigation program.
Nitrate nitrogen ensures the complete absorption of calcium by the root system of the plant. Prevents the development of tomato blossom end rot, lettuce leaf scorch and other physiological disorders associated with calcium deficiency. Optimal for foliar application. Granular calcium nitrate is not hygroscopic, does not cake, and is easy to use.
