CalPhos is a true di-calcium phosphate based on the same proven process pioneered by Hatuma. Designed for local conditions, it delivers sustainable fertility, minimal leaching, and strong pasture performance across all farming systems — from hill country to dairy platforms.

CalPhos grows more grass, improves soil health and costs less than similar alternatives. 

Key Benefits:

• Boosts clover, nitrogen fixation, and pasture quality & amp; DM
• Minimises leaching and improves phosphate availability
• Promotes soil structure, root health, and microbial activity
• Supports animal health and reduces compaction
• Compatible with biological additives for enhanced performance

CalPhos and CalPhos-HP are designed to give farmers a stronger pasture response than superphosphate, without chasing high Olsen P numbers. 

Independent NZ trials on dicalcic-type fertilisers showed: 

• 10-20% more pasture grown than superphosphate
• Better clover activity
• More even seasonal growth
• Stronger response at moderate Olsen P levels 

CalPhos helps use P more efficiently. It also helps lift soil PH, reduce aluminium toxicity and reduce the risk of P loss to waterways.
