Fosto is a liquid fertilizer suitable for usage during the entire vegetation of the plant. Phosphorus,
Magnesium, Zinc and Manganese fertilizer with amino acids has a complex effect on plants and soil. It is a
source of energy, a connection between a plant and soil, water retention in a plant and soil.
Phosphorus is responsible for nutrient uptake, photosynthesis and energy metabolism, strengthens immune
system of a plant. Phosphorus pentoxide is effective against diseases caused by Oomicetes fungi (mold,
Phytium, Phytophthora). Phosphorus is energy, which is part of the phospholipids of cell membranes. It is
especially important that there would not be deficiency of phosphorus in plants in the early stages of growth.
Magnesium stimulates carbohydrate metabolism, accelerates maturation, and increases the amount of dry
matter in the seeds. It decreases the efficiency of nitrogen and phosphorus fertilizers.
Manganese stimulates development of the root system, formation of new shoots, sugar production in leaves
and transportation to roots, improves assimilation of iron from the soil and reduces the likelihood of chlorosis.
Zinc, like phosphorus and manganese, is very important at the beginning of vegetation. Zinc is an essential component of enzymes in photosynthesis, significant for grain formation. There is usually lack of it in soil with a pH below 6.5 and when a pH is above 7.
L-amino acids provide the plant with the energy needed to restore photosynthesis, metabolic processes, promote growth and development.

Fosto can be used in mixtures with many fertilizers and pesticides (insecticides, fungicides). Do not use with products
containing high amounts of copper (Cu), sulphur (S), mineral oils and with alkaline products (pH > 8), with herbicides and
with seed treatment where the label states “do not mix with fertilizers“. Before mixing it is recommended to make a small
amount of the mixture in order to check whether there is no sediment. It is recommended to spray in a small area in
order to check whether there are no phytotoxic effects on plants.
