Simplot Triple Superphosphate 0-45-0 Fertilizer 50 lb bag

Simplot Company Simplot (TSP) Triple Superphosphate 0-45-0 Fertilizer 50LB Bag Part# 12030 * Simplot (TSP) Triple Superphosphate (0-45-0) is a fertilizer rich in phosphorous and calcium. This product can be mixed into the soil before planting or used as a top dress. * TSP has several agronomic advantages that made it such a popular P source for many years. It has the highest P content of dry fertilizers that don’t contain nitrogen (N). Over 90 percent of the total P in TSP is water soluble, so it becomes rapidly available for plant uptake. As soil moisture dissolves the granule, the concentrated soil solution becomes acidic. TSP also contains 15 percent calcium (Ca), providing an additional plant nutrient. * A major use of TSP is in situations where several solid fertilizers are blended together for broadcasting on the soil surface or for application in a concentrated band beneath the surface. It’s also desirable for fertilization of leguminous crops, such as alfalfa or beans, where no additional N fertilization is needed to supplement biological N fixation. Management Practices: - The popularity of TSP has declined because the total nutrient content (N + P?O?) is lower than ammonium phosphate fertilizers such as monoammonium phosphate, which by comparison contains 11 percent N and 52 percent phosphorous pentoxide (P?O?). Costs of producing TSP can be higher than ammonium phosphates, making the economics for TSP less favorable in some situations. - All P fertilizers should be managed to avoid losses in surface-water runoff from fields. Phosphorus loss from agricultural land to adjacent surface water can contribute to undesired stimulation of algae growth. Appropriate nutrient management practices can minimize this risk. Non-Agricultural Uses: - Monocalcium phosphate is an important ingredient in baking powder. The acidic monocalcium phosphate reacts with an alkaline component to produce carbon dioxide, the leavening for many baked products. Monocalcium phosphate is commonly added to animal diets as an important mineral supplement of both P and Ca.
