Enhancing phosphorus phytoremedation potential of two warm-season perennial grasses with nitrogen fertilization
Phytoremediation or use of plants to extract soil nutrients is a practice used to ameliorate the impacts of excessive soil nutrients. Pensacola bahiagrass (Paspalum notatum Flügge) and ‘Floralta’ limpograss [Hemarthria altissima (Poir.) Stapf & Hubb] were grown in a P-impacted Immokalee fine sand (Mehlich-1 P 30 mg P kg–1) to evaluate increasing N levels on dry matter yield (DMY), forage P ...
