IN2 /NPK 13-13-13+TE

NPK 13-13-13+TE is a liquid trace element fertilizer also containing nitrogen (N), phosphorus (P), and potassium (K) intended for foliar spraying of plants.
Nitrogen is imperative for plants to ensure their good development and growth. It stimulates and regulates many vital and growth-related processes of the plant. It is very important for protein formation too. Nitrogen majorly contributes in the formation of protein molecules in plants and is an important component of chlorophyll, without nitrogen photosynthesis is impossible. The rich green color of the leaves and fast-growing shoots indicates sufficient nitrogen. When there is a lack of nitrogen, leaves turn yellow and plants grow more slowly.
Phosphorus is essential for plant vegetation; it is an element that regulates vital processes and growth. It strengthens the plants’ natural immunity and affects the formation and accumulation of sugar. There mustn’t be a phosphorus deficiency in the plants in the early stages of growth. The roots of young plants are particularly sensitive to the deficiency of phosphorus. Poorly developed roots do not absorb other nutrients (e.g. nitrogen) well enough. In the absence of these substances, the aerial parts of the plant also grow poorly.
Potassium increases resistance to low temperatures, controls the function of the stomata in the leaves, and thus reduces the loss of water in the plant. The optimal amount of potassium forms a strong root system, which ensures good absorption of other nutrients and improves tillering.

  • increases the uptake of nitrogen fertilizers,
  • ensures the nutrient balance in a plant,
  • improves germination and tillering of a plant,
  • improves the formation of roots and inflorescences,
  • improves the quality of the yield,
  • improves resistance to drought, frost, and diseases.

NPK 13-13-13+TE can be used in mixtures with many fertilizers and plant protection products. Do not use with products containing high amounts of copper (Cu), sulfur (S), mineral oils, and with alkaline products (pH>8). Before usage, it is recommended to make a small amount of the mixture to check if the sediment does not form, then spray in a small area and observe whether it does not have phytotoxic effects on plants.
