Osmo Pro 9-3-3 is an organic fertilizer that contributes to soil organic matter and soil fertility. The mix of organic raw materials makes for a sophisticated compound fertilizer with a controlled release of nutrients over time.

The period of releasing nutrients lasts from a minimum of 90 up until 120 days. Osmo Pro 9-3-3 is especially suited for the vegetative growth phase. Due to the high amount of nitrogen, the development of roots, leaves, stems and vegetative organs are stimulated. This is also a good fertilizer to start the growing season with or to be used complementary with other fertilizers. The addition of seaweed has a positive effect on photosynthesis and plant stress.
