Summary
The effects of Huma Gro® Turf SUPER PHOS® were compared with competitive phosphorus fertilizers on the shoot biomass of Bermuda grass, a common warm-season turf grass species.
Bermuda grasses were grown in Hoagland solution prepared without phosphorus or nitrogen. The treatments, replicated four times, consisted of the following fertilizers at 10% and 25% phosphorus:
SP: Huma Gro® SUPER PHOS® solution (0-50-0)
AP: Ammonium polyphosphate solution (10-34-0)
MAP: Monoammonium phosphate granular (11-52-0)
TSP: Triple superphosphategranular (0-45-0)
Control: Untreated control
Nitrogen was added to SP and TSP to ensure a uniform amount of nitrogen throughout the treatments. Grasses were grown for approximately two months and shoots were harvested weekly. Fresh and dry weights were measured and recorded over eight weeks.
Results
Bermuda Shoot Fresh and Dry Weights at 10% and 25% Phosphorus
-
Bermuda Shoot Fresh Weight at 10% Phosphorus -
Bermuda Shoot Fresh Weight at 25% Phosphorus -
Bermuda Shoot Dry Weight at 10% Phosphorus -
Bermuda Shoot Dry Weight at 25% Phosphorus
Huma Gro® Turf SUPER PHOS® contributed to a higher Bermuda grass shoot biomass than the competitive products at the same reduced rate of applied phosphorus. The beneficial effect on shoot fresh and dry weights was classified as follows: SP> TSP > MAP > AP > control.
