Use of Recovered Struvite and Ammonium Nitrate in Fertigation in Tomato (<i>Lycopersicum esculentum</i>) Production for boosting Circular and Sustainable Horticulture

Struvite and ammonium nitrate are products obtained from widely studied processes to remove phosphorus (P) and nitrogen (N) from waste streams. To boost circularity in horticulture, these recovered products should be applied to edible crops. Particularly, struvite has not been implemented in fertiga...
