In many countries, color additives are subject to strict regulations to ensure their safety for consumption. In the United States, the Food and Drug Administration (FDA) oversees the use of color additives, requiring rigorous testing and evaluation before approval. Each additive is assigned a designation, with some being approved for food use, while others are restricted or banned due to potential health risks. Similar regulatory bodies exist in other regions, such as the European Food Safety Authority (EFSA) in the European Union.

Therefore, soil testing and precise application methods should be integrated into fertilization practices to ensure that KNO3 is used efficiently and effectively.
