High-phosphorus NPK compound fertilizers are specifically designed to meet the phosphorus demands of crops during critical reproductive growth stages (flowering/fruiting/root system development).

For Phosphorus-Deficient Soils: Select ultra-high phosphorus formulas (e.g., 13-40-13) to rapidly correct phosphorus deficiency disorders.

Energy Transfer: Phosphorus is a key component of ATP/nucleic acids, promoting flower bud differentiation and cell division.

Root System Development: Stimulates feeder root growth, increasing nutrient uptake efficiency by >30%.

Stress Resistance Enhancement: Reinforces cell membrane stability, reducing damage from frost/drought stress.

Critical Warning:

After 3 consecutive years of high-P fertilizer application, conduct soil phosphorus testing to prevent:

Zinc/iron deficiency (due to phosphorus-induced antagonism)

Water eutrophication (from phosphorus leaching).
