Ferasium is a highly concentrated solution made from phosphorus and potassium, which all phosphorus comes from phosphite anion (H2PO-3). Ferasium acts as an activator of plant defense against possible diseases caused mainly by fungi and bacteria. It strengthens the stem,roots, and leaves, and decreases the damage caused by pathogens. It also also prevents rotting in high-humidity conditions. Potassium intervenes in the water regulation mechanisms of the plant, in the formation of proteins and the synthesis of carbohydrates (starch and cellulose). It serves as an activator in the processes of cellular respiration and enables the active formation of many enzymes involved in metabolic processes. Moreover, it also regulates the transportation of products derived from the photosynthesis by phloem. Enhances plant resistance to drought, frosts, and fungal diseases by increasing the mechanical resistance of the stems and by strengthening the root system. It also participates in the development and ripening process of the fruits. Ferasium is a fertilizer that promotes the natural defenses of the plant against diseases and climate conditions
