VitaFer® Si is a new suspension fertilizer, characterized by anti-stress properties. It stimulates the plant's immune system, growth and development.

VitaFer® Si contains 25,6% of easily assimilable silicon (SiO2) that forms the cell wall (”protective filter”) reinforcement and inhibits microbial penetration. Additionally, it prevents evaporation of water from plants, what has a direct impact on the improvement of the photosynthesis process and absorption of nutrients.

VitaFer® Si is environment-friendly and fully biodegradable.

Key advantages of VitaFer® Si

  • Increased tolerance of plants to unfavorable crop conditions (eg drought and other abiotic stress),
  • limited impact of biotic stress caused by pathogens and / or pests,
  • higher resistance to unfavorable weather conditions (drought, inadequate salinity of the soil, low temperatures)
  • stimulation of root growth,
  • reinforced plant cell walls, increasing resistance to mechanical damage (eg during harvest),
  • less evaporation of plant water,
  • increased photosynthesis,
  • stimulation of the absorption and utilization of nutrients from soil,
  • improvement of yield, quality and storage properties of crops.
