VitaFer® K is an advanced potassium fertiliser enriched with nitrogen, phosphorus, and micronutrients (B, Cu, Mn, Mo, Zn), developed to support crop quality and plant tolerance to abiotic stress. The formulation provides comprehensive supplementation of key nutrients during critical yieldforming stages. The product is intended for agricultural, vegetable, and fruit crops, where potassium plays a key role in water management, assimilate transport, and the development of plant resilience.

Description

Key effects:

Optimisation of Water Management and Cell Turgor
The product regulates stomatal function and water transport, increasing drought tolerance and water use efficiency.

Improved Crop Quality and Market Parameters
Supports sugar transport to storage organs, increases sugar, vitamin, and dry matter content, improving crop storability and market value.

Strengthened Cell Walls and Plant Resistance
The product activates lignin and phytoalexin synthesis, reducing susceptibility to fungal and bacterial diseases.

Nutrient Synergy
The combination of nutrients helps eliminate hidden deficiencies and optimises photosynthesis, protein synthesis, and the activity of enzymes essential for plant metabolism.

Flexible Application in Intensive Programmes
The low pH (5.5–7.5) ensures stability in tank mixtures, enabling efficient combined treatments with NPK fertilisation and crop protection products.

The role of potassium in crops: 

  • is responsible for the quantity and quality of the yield 
  • participates in the regulation of nitrogen uptake 
  • is responsible for the water management in plants 
  • contributes to building resilience to drought conditions 
  • promotes the development of the root system and the uptake of other nutrients from the soil 
  • increases the frost resistance of plants 
  • is involved in the formation of starches and sugars. 

Potassium deficiencies result in:

  • Inability to defend themselves against drought stress: plants lose their turgor and start to wilt
  • Yellowing of leaves progressing from the edges. Over time, the leaves wilt, turn brown and die
  • The plants are smaller, with a shorter and more flaccid stem
  • Delayed flowering, flowers are noticeably smaller
  • Limited ear and cob formation, poor grain pouring

Dosage and timing of application:

Crop Rate (l/ha) Applications
Field crops 5 1–2 applications from the 4–6 leaf stage / tillering / initial stage of intensive growth
Fruit and berry crops 5 1–2 applications from the 4–6 leaf stage / tillering / initial stage of intensive growth
Vegetables 5 2–3 applications during the intensive growth stage
Vegetables 0,2-0,3% Depending on the needs of the crop
