What is one of the main uses of ammonia?

Ammonia is primarily recognized for its role in the production of nitrogen-based fertilizers, which is crucial for agriculture. Nitrogen is an essential nutrient that plants need for growth, and fertilizers containing ammonia or its compounds provide a readily available source of this nutrient. When applied to the soil, ammonia helps increase crop yields by supplying the nitrogen necessary for processes such as protein synthesis and chlorophyll production, which are vital for plant health and productivity.

While ammonia is also used in cleaning agents, as a refrigerant, and in the manufacturing of plastics, its most significant and widespread application remains in agriculture as a key component of fertilizers. This agricultural use highlights the importance of ammonia in supporting food production and enhancing soil fertility, making it a fundamental chemical in the field of food security.
