Osmo Pro 9-3-3

Solid Fertilizer

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

The period of releasing nutrients is minimum 90 to 120 days. Osmo Pro 9-3-3 is especially suited in the vegetative growth phase. Due to the high amount of nitrogen the development of roots, leaves, stems and vegetative organs will be stimulated. Also a good fertilizer to start up the growing season or complementary with other fertilizers. The addition of seaweed has a positive effect on photosynthesis and plant stress. Osmo Pro 9-3-3 is certified for use in organic agriculture EC 834/2007 and EC 889/2008.
