Market Size
The global magnesium nitrate market size was valued at USD 526.80 million in 2023 and is estimated to grow in 2024 and 2025 in line with rising industrial and agricultural demand.
The market is projected to reach USD 736.92 million by 2032, expanding at a CAGR of 3.8% during the forecast period (2024–2032).
Market Overview
Magnesium nitrate is a hygroscopic salt commonly produced by reacting magnesium oxide or magnesium hydroxide with nitric acid. It is primarily used as a fertilizer additive, chemical reagent, oxidizing agent, and catalyst in industrial processes. Its high solubility in water and compatibility with other nutrients make it suitable for fertigation and foliar applications in agriculture.
Straits Research indicates that the market is supported by the increasing focus on improving crop yields, growing industrialization in emerging economies, and rising demand for specialty chemicals. Magnesium nitrate is also used in the manufacture of pyrotechnics, explosives, ceramics, and pharmaceutical formulations, further broadening its end-use base.
The market is benefiting from advancements in chemical processing technologies and improved logistics infrastructure, which are enabling efficient large-scale production and distribution.
Market Drivers
Rising Demand for High-Efficiency Fertilizers
One of the primary drivers of the magnesium nitrate market is the growing demand for high-efficiency and water-soluble fertilizers. Magnesium is an essential secondary nutrient required for chlorophyll synthesis and enzyme activation in plants, while nitrogen supports vegetative growth.
Straits Research highlights that magnesium nitrate is increasingly used in fertigation systems and greenhouse cultivation due to its rapid nutrient availability and compatibility with drip irrigation technologies. The rising adoption of precision agriculture practices is further driving demand for magnesium nitrate-based fertilizer formulations.
Expansion of the Chemical and Industrial Sector
The expanding chemical manufacturing sector is another major growth driver for the magnesium nitrate market. Magnesium nitrate is used as a precursor in the production of catalysts, specialty chemicals, and laboratory reagents.
Its application as an oxidizing agent in pyrotechnics and explosives is also contributing to market growth, particularly in defense and mining-related activities. Straits Research notes that rising industrial output and infrastructure development in Asia-Pacific and Latin America are supporting increased consumption of magnesium nitrate.
Growing Use in Wastewater Treatment and Environmental Applications
Magnesium nitrate is used in wastewater treatment processes to control hydrogen sulfide formation and reduce odors in sewage systems. It also plays a role in nutrient removal and sludge stabilization.
The increasing emphasis on environmental protection, stricter wastewater discharge regulations, and rising investments in municipal water treatment infrastructure are driving demand for magnesium nitrate in environmental applications.
