Green manures are crops grown primarily for the purpose of improving soil fertility. They include legumes such as clover and vetch, which fix nitrogen from the atmosphere and enrich the soil. After a designated growth period, these crops are tilled back into the soil, contributing organic matter and nutrients. Cover crops also help prevent soil erosion and suppress weeds, making them a vital component of sustainable agricultural practices.

Sorbic acid occurs naturally in food, and—as stated above—potassium sorbate is the salt of sorbic acid. Sorbic acid is colorless and slightly water-soluble and originated as an organic matter, though it is often produced synthetically today.
Trichloroisocyanuric acid, commonly referred to as TCCA, is a versatile chemical compound widely used in various applications, primarily in swimming pool sanitation, water treatment, and disinfection. Its significance lies in its ability to provide a stable source of chlorine, making it an essential agent in maintaining cleanliness and safety in recreational water environments.
Sulfur dioxide has a long history of use as a food preservative. It was utilized by ancient civilizations, dating back to the Romans, who employed it to preserve wine. The rejuvenation of interest in food preservation techniques has seen a resurgence with the rise of industrial food production. SO2 helps to extend the shelf life of products by inhibiting the growth of spoilage organisms, such as bacteria and molds, and slowing the oxidation processes that lead to rancidity and discoloration.
