We’re working with Ostara to solve one of the world’s biggest challenges: conserving our natural resources while producing more food. 

Ostara produces a phosphate material, both manufactured and recovered from waste-water streams, which allows growers to apply the most efficient source of phosphorus – a finite global resource and essential plant nutrient – that is always available, minimally water soluble and which improves yields as well as reduces pollution. 

Unlike conventional fertilisers, the nutrients in Ostara’s Crystal Green products are only released when triggered by natural chemical reactions in the growing roots of plants, increasing phosphate uptake. 

This is proven to improve crop performance, increasing yields, while reducing nutrient run off, protecting our waterways from pollution by up to 75%. Applied to turf, such as at English Premier League side Southampton Football Club, studies by Cornell University showed it continuously releases essential nutrients to develop denser roots, improving wear and stress tolerance, while also lowering the risk of phosphorus leaching and runoff.

Ostara’s Pearl technology is rooted in the circular economy (reducing waste and pollution, keeping resources in use and restoring natural systems) by recovering phosphorus from wastewater treatments sites in cities, on farms and from industry. Its technology transforms essential nutrients into crystallised granules which are harvested, dried and bagged, ready for distribution as environmentally responsible fertiliser. Ostara is the world’s leader in nutrient recovery with 22 commercial installations worldwide.
