Bio-Friendly Phosphate & Calcium for Soil Regeneration
NTS Soft Rock™ is a colloidal calcium phosphate fertiliser designed to provide a long-term source of phosphorus, calcium, silicon and trace elements without the lock-up issues commonly associated with conventional phosphate fertilisers.
This naturally occurring soft rock phosphate contains plant-available phosphorus, approximately 20% calcium, beneficial silicon and a broad range of trace elements to support soil health and plant performance. Its colloidal structure helps maintain nutrient availability while supporting beneficial soil biology.
Suitable for regenerative agriculture, landscaping, tree planting and soil improvement programs, Soft Rock™ helps re-mineralise depleted soils and build long-term fertility.
