Product benefits
- Australian Certified Organic (ACO) Registered Farm Input 456AI.
- All elements are in colloidal form. This provides ongoing plant availability.
- NTS Soft Rock™ is an unprocessed phosphate; Nutri-Tech notes processed phosphate fertilisers can contain high levels of the heavy metal cadmium.
- Exceptional trace element levels.
- Helps re-mineralise soils.
- Colloidal calcium component (approx. 20%) is much more plant available than limestone.
- High in silicon. Research suggests increased brix levels in plants are related to the presence of silica.
