Used primarily as a fertilizer in agriculture due to its high phosphorus and nitrogen content, supporting root development and early plant growth. Commonly applied in blends for lawns, gardens, and crops where controlled release of nutrients is needed. Also serves as a flame retardant in textiles and wood-based materials by promoting char formation and reducing flammability. Utilized in some food products as a leavening agent in baked goods. Plays a role in laboratory settings as a buffering agent in analytical chemistry and in the preparation of nutrient media for microbial cultures.
