RealStrong N-Bio contains a free-living nitrogen-containing bacterium, Bacilus sp. which is capable of converting nitrogen gas in the atmosphere (insoluble) to ammonia (NH3), nitrite (NO-2) or nitrate (NO-3) or nitrate (NO -3), which can be absorbed by plants and converted to protein and nucleic acids for plant growth. Therefore, nitrogen-binding bacteria are one of the main functional bacteria in the bio-fertilizer formula. This fertilizer has been tested and suitable for fruit trees and vegetables with leaves.
