Deluge of dog pee and poo harming nature reserves, study suggests

Urine and faeces creating nitrogen and phosphorus levels that would be illegal on farms, scientists calculate

The analysis found that the resulting overfertilisation of the ground with nitrogen and phosphorus by footpaths could reach levels that would be illegal on farmland.
