| Abstract/Contents: | "Revolving algal biofilm can be used to harvest nutrients, which produces algae that could be a fertilizer. A randomized complete block design study with five replications in a greenhouse was conducted for 120 days at Iowa State University to test the performance of algae produced from sewer sludge on a revolving algal biofilm on turfgrass growth in rooting tubes. Fertilizers tested included: urea, pure algae, pure algae + bacteria (blended algae), pure algae + urea, blended algae + urea, Milorganite, a synthetic slow-release fertilizer, and a non-treated control all applied at 24 kg N ha-1 every 30 days. Turfgrass performance was evaluated based on the following parameters at the conclusion of the study: longest root and shoot length, shoot biomass, root biomass, total root length, root surface area and root volume. All data were subjected to analysis of variance and mean comparisons with Fishers protected least significant difference at p =0.05. All treatments receiving fertilizer had greater total root length than the non-treated. Blended algae increased longest root length (129% and 152%), total root length (162% and 290%), root surface area (171% and 358%), and root volume (180% and 441%) compared to urea and the non-treated. Pure algae, Milorganite, and the slow release treatments all had a longest root measurement greater than the non-treated control. Pure algae (142%) and Milorganite (148%) also offered greater total root length than urea. Applications of the pure algae and blended algae increased root growth, but did not improve the root growth when urea was added to the fertilizer. Shoot growth was similar to commercially available fertilizer for the pure algae and blended algae fertilizers. Further research should focus on the timing of applications to better develop a release curve and should incorporate more turfgrass species to test for safety." |
