Mixture of Trace Elements

Speedfol Combine is a crystalline fertilizer contains mixture of trace elements like boron, copper, iron, manganese, molybdenum and zinc. Product focused on to prevent or treat micro nutrient deficiencies.With the special additives inside plants absorb nutrients faster and easier. Speedfol Foliar range phytotoxicity, scorching risk and possibility of leaf damage is very low compared to other foliar products. When it is applied, it prevents plant nutrition deficiencies and corrects deficiencies quickly if exists.

Micro nutrients inside Speedfol Combine are essential elements for plants and their roles are critical for many different plant metabolic processes. Boron is taking role at pollination. Copper is taking role at respiration. Iron is taking role at energy cycles and chlorophyll synthesis. Manganese is taking role at chloroplast synthesis and respiration. Molybdenum is taking role at protein synthesis and biological nitrogen fixation. Zinc is taking role at plant hormones synthesis.


  • Suitable for both soil and foliar application
  • All six essential micro elements inside
  • Contains adjuvants for better absorption
  • Very low scorching risk
  • Not phytotoxic between recommended dosage
  • Prevent micro nutrient deficiencies with regular use
