IN3 /NPK 4-21-29 + 25SO3

Liquid fertilizer, containing nitrogen (N), phosphorus (P), potassium (K), sulfur (S). Phosphorus is very important for plant vegetation, it is an element which regulates vital processes and growth. Strengthens natural immunity of plants, affects formation and accumulation of sugar. It is especially important that plants do not experience phosphorus deficiency in the early stages of growth. Potassium increases resistance to low temperatures, controls function of stoma in leaves and thus reduces loss of water in plant. Sulphur stimulates photosynthesis, chlorophyll production, respiratory processes, metabolism of nitrogen and carbon, the formation of many vitamins, enzymes and essential oils. Oilseeds in particular have a higher need for sulfur.

IN3 /NPK 4-21-29+25SO3 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). 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.
