Global Ammonium Sulphate Fertilizer Market Strategic Research Report

Scope of the Report

The global Ammonium Sulphate Fertilizer market size is predicted to grow from US$ 6,072 million in 2025 to US$ 7,676 million in 2032; it is expected to grow at a CAGR of 3.4% from 2026 to 2032.

Ammonium sulphate [(NH4)2SO4] is one of the earliest and most widely used nitrogen fertilizers for crops, primarily serving to supply the nitrogen and sulfur nutrients required for plant growth. Its active ingredients are nitrogen and sulfur. Proper application helps maintain optimal nitrogen levels in the soil and—in the case of alkaline soils—helps preserve a favorable pH balance. However, excessive application can lead to adverse effects, such as excessive leaf growth, plant weakening, and the accumulation of excessive thatch in turfgrass. This fertilizer can be applied alone or in combination with other fertilizers; it is water-soluble—allowing for application via soil drenching or irrigation systems—and can also be sprayed as a foliar fertilizer. In 2025, global sales volume for ammonium sulphate fertilizer reached 29.459 million tons, with a production capacity of approximately 42 million tons, an average selling price of $210.7 per ton, and an average gross profit margin of 15%–20%.

According to the 2025 Statistical Yearbook of the United Nations Agricultural and Food Organization, over 800 million people worldwide are engaged in agriculture—representing more than a quarter of the global workforce—and generate over $3 trillion in value-added output. Analytical data indicates that in 2025, North America was the region with the highest fertilizer consumption, accounting for 32% of the global market. In terms of demand, the adoption rate of micronutrient fertilizers has reached 45–60% in many European countries and as high as 60–70% in the United States.

Global agricultural subsidy policies and food security strategies continue to underpin the demand for ammonium sulfate; government price interventions for nitrogen fertilizers have bolstered demand resilience, particularly in India, Brazil, and Southeast Asia. Meanwhile, environmental regulations have driven an increase in ammonium sulfate production—a byproduct of flue-gas desulfurization in the steel and coking industries—introducing a degree of "industrial byproduct volatility" to the supply. Recent geopolitical tensions and fluctuations in energy prices have also indirectly impacted the stability of the sulfur fertilizer supply chain.
