Preservative, mineral, or synthetic, used in meat-based products.

Magnesium sulfate, also known by its chemical formula MgSO4 (anhydrous) or MgSO4·7H2O (heptahydrate), is a versatile compound widely used across various industrial and food sectors. With a molecular weight of 246.47 g/mol (heptahydrate) or 120.37 g/mol (anhydrous), it plays a critical role in numerous applications.

These are general aspects of iron, and its significance varies across scientific, industrial, and nutritional contexts.

Urea contains 46% nitrogen in the chemical form of urea CO(NH2)2, making it a nitrogen fertilizer. Urea is in organic form, requiring transformation before it can be assimilated by the plant

Potassium Sulfate (K₂SO₄) is an inorganic salt commonly used in the fertilizer industry. It is available as a white crystalline powder, odorless, non-flammable, and sparingly soluble in water.

Calcium nitrate appears as white crystalline granules or powder, odorless, and highly soluble in water. It is hygroscopic, readily absorbing moisture from the air, requiring storage in dry conditions.

Manganese is a transition metal with a silvery color, typically found in powder or granular form. It is relatively hard and lightweight, with a strong affinity for oxygen, forming oxides in the presence of air.

Monoammonium Phosphate (MAP) appears as a white, odorless crystalline powder, highly soluble in water. 

Monopotassium phosphate (MKP) appears as a white, crystalline, odorless powder, highly soluble in water. 

Zinc is presented as a silver-gray, crystalline, and odorless powder. It is combustible but minimally flammable and insoluble in pure water, though it dissolves in acids and alkalis

Boron is a chemical element that appears as a white crystalline powder and is odorless, with low flammability and low solubility in water. It is slightly soluble in organic solvents

Molybdenum is a gray-silver, metallic powder that is odorless and non-flammable. It is chemically stable at room temperature, insoluble in water, and soluble in strong acids.
