The global Ammonium Phosphite Fertilizer market size is predicted to grow from US$ 574 million in 2025 to US$ 822 million in 2032; it is expected to grow at a CAGR of 5.3% from 2026 to 2032.

Ammonium phosphite fertilizer is a water-soluble phosphorus fertilizer in which phosphorus is present in the phosphite (PO???) form rather than the conventional phosphate form, typically produced by neutralizing phosphorous acid with ammonia to form mono- or diammonium phosphite salts; it is primarily used as a foliar spray or fertigation input to stimulate plant metabolic activity, enhance phosphorus uptake efficiency, and induce plant defense responses against certain pathogens, rather than serving as a direct bulk phosphorus nutrient source. The supply chain begins upstream with elemental phosphorus production (from phosphate rock) and ammonia synthesis (via the Haber-Bosch process), followed by midstream conversion of elemental phosphorus to phosphorous acid, controlled neutralization with ammonia, formulation into liquid or soluble powder products, and blending with adjuvants or micronutrients. Downstream, products are distributed through agricultural input distributors, specialty fertilizer suppliers, and crop-protection channels, with end users including horticulture, fruit and vegetable growers, turf management, and high-value crops where foliar efficiency and stress resistance are critical. In 2025, the global ammonium phosphite fertilizer market recorded an annual production volume of approximately 390,000 tons against an estimated global production capacity of about 470,000 tons per year, with average unit prices ranging from USD 1,150 to 2,100 per ton, while the industry maintained an average gross margin of around 27%.
