Evaluation of Algae-Based Fertilizers Produced from Revolving Algal Biofilms on Kentucky Bluegrass

The revolving algal biofilm (RAB) system is a wastewater treatment method that effective at removing nutrients from wastewater, and as result produces algae could be used sustainable fertilizer source. A two-year greenhouse study was conducted to investigate if algae-based fertilizers produced the RAB an turfgrass fertilizer. Fertilizer treatments included pure (PA), + cellulosic filler (Blended), Milorganite, urea, nontreated control. Overall, in terms of percent green cover (PGC), Blended PA performed similar Milorganite outperformed urea At conclusion study, only have increased PGC relative which 29% increase. On average throughout duration resulted dark color index (DGCI) Blended, PA, 50% 111% greater total root length compared control, respectively. Furthermore, 107% 136% surface area volume, respectively, Pure 58% longest by 22% urea. Additionally, 114% 110% shoot biomass had or better growth, cover, color, rooting. Thus, (PA Blended) should considered effective,
