Phosphorus (P) is considered a primary crop nutrient, along with nitrogen and potassium. Phosphorus is involved in photosynthesis, respiration, energy storage and transfer and many other processes in the plant. Phosphorus improves the quality of fruit, vegetable, and grain crops, and is vital to seed formation. Phosphorus uptake is a continuous process during the active growth period of plants. Phosphorus is absorbed by plants throughout the growing season, with much of the plant’s phosphorus need occurring during periods of fast vegetative growth and fruit production. Since phosphorus is needed at all stages of plant growth it is imperative that the nutrient be in a plant available form throughout the growing season.
Most phosphate fertilizers combine, or complex, with other minerals in the soil to create compounds that are not usable to plants. This can happen in as little as 4 to 8 days. Pro-Germinator™ contains both orthophosphate, which is immediately available to the plant, and long-chain polyphosphates that are protected by flavonol chelation technology resulting in season long phosphorus availability.
The combination of ortho- and polyphosphates, along with its flavonol chelation technology allows Pro-Germinator™ to provide more nutritional performance per gallon than conventional fertilizers. That results in having excellent crop nutrition at lower application rates than other phosphate products. When applied at recommended rates, Pro-Germinator™ is cost effective, on a per acre basis. Pro-Germinator™ should be the backbone of all crop fertility programs, potentially providing the greatest return on phosphorus investment.
An experiment was conducted at the AgroLiquid North Central Research Station to determine phosphate availability of Pro-Germinator™ compared to other liquid phosphate fertilizers. Pro-Germinator™, 9-18-9 orthophosphate, and 10-34-0 ammonium polyphosphate were applied at 20 lb P2O5 per acre. Plant usable phosphorus in soil solution was measured at various times throughout the growing season.
