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.
Bermuda Shoot Fresh and Dry Weights at 10% and 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.
SUPER PHOS® (0-50-0) complexed with Micro Carbon Technology®* can be applied by foliar application, according to label directions, without the risk of phytotoxicity and keeps phosphate available and soluble in the soil solution for rapid uptake by plant roots without being blocked by clays, metal ions, or organic matter. Phosphate encourages the production of amino acids, proteins, and carbohydrates necessary for cellular division.
* Huma Gro® Turf products with Micro Carbon Technology® rapidly deliver essential nutrition to crops for optimal growth, fruiting, and vigor. The results are higher quality harvests, increased crop yields, and maximum profit.
