A Sustainable Path to Maximize Yield and Protect the Environment

Phosphate is a Critical Nutrient–In the Right Amount and the Right Place 

Phosphate is an essential nutrient and a building block of life. Conventional sources of phosphate fertilizer are highly inefficient and water soluble. Every growing season, over 80% of applied phosphate is lost to soil tie-up, nutrient runoff and leaching. If mismanaged, it can cause nutrient overloads in waterways, contributing to toxic algae blooms harmful to aquatic life.

Keep Phosphate Where It Counts 

Due to its unique solubility, Crystal Green fertilizers are only available to growing crops, so nutrients don’t leach into the ground or runoff into waterways. The nutrients remain available in the soil all season to meet your crops demand for nutrients. 

Reclaim Phosphate 

Wastewater streams can contain high amounts of phosphate and nitrogen that are available to be reclaimed and developed as a high-efficiency fertilizer with our nutrient recovery solutions.

Sustainable Results

Our sustainable nutrient solutions reduce the amount of phosphate in the environment by helping to preserve our global reserves of this finite, yet critical, nutrient while delivering nutrients back to crop roots and keeping them out of global water systems.

Make the Sustainable Fertilizer Choice

Crystal Green fertilizers remain crop available to prevent soil tie-up and avoid nutrient runoff and leaching for maximum efficiency and uptake, resulting in maximum yield potential. 

Avoid Runoff and Leaching

Crystal Green fertilizers reduce nutrient runoff and leaching back into the environment — they are only activated by roots. 

Reduce Phosphate Applied

Driven by Crystal Green’s high efficiency, farmers have the potential to reduce P2O5 application rates.

Grow Crops Sustainably

Apply phosphates that can produce more with less and protect our environment.

Recover Nutrients from Wastewaters

Ostara’s nutrient recovery technology transforms excess nutrients in wastewater into a revenue-generating source of sustainable phosphate fertilizer. 

Protect Waterways

Ostara’s nutrient recovery solutions reduce the cost of meeting wastewater discharge limits, while also improving water quality by producing a high-efficiency phosphate fertilizer that reduces nutrient runoff and leaching. 

Reduces Use of Water Treatment Chemicals

When treatment facilities use our sustainable solutions to remove nutrients, they can also reduce chemical usage and sludge volumes. 

Reduces Excess Phosphate in the Environment

Our nutrient recovery technology removes and reuses phosphate from wastewater to develop Crystal Green Pearl. With Crystal Green’s unique solubility, phosphate is only available to growing roots instead of ending up in nearby waterways.
