First genomic evidence of inbreeding in South American pumas and the role of Andean climate history in shaping genetic diversity

Imported phosphate for fertiliser is expensive – could this homegrown alternative be a solution?

Research shows a phosphorus-rich compound found in wastewater raises uptake by plants and reduces discharge to waterways.

• Struvite, phosphorus-rich compound, recoverable from wastewater
• Field trial showed 30% increase in plant phosphorus absorption
• Struvite could replace conventional fertilizers partially in NZ
