NTS Soft Rock™

Full season phosphate supply without the lockups. NTS Soft Rock™ is a bio-friendly, colloidal clay-based rock phosphate. A colloidal calcium phosphate that can never lock up, in stark contrast to all other phosphate sources. This exceptional fertiliser includes 8 – 9% phosphorus, 19.3% calcium, a high analysis of silicon and a rich lode of trace elements. A microbe friendly bio-phosphate, which is an integral part of our soil regeneration program. This is one of the few phosphate sources that do not have problems with high levels of the heavy metal cadmium.
