Ferro Silicon (FeSi)
Super Silicon Voga are natural silicon rich minerals that contain high amount of active silicon and other beneficial nutrients. Super Silicon Voga contains over 5,000 ppm of plant available silicon, 20 times higher than other brands. Silicon is known to be absorbed by plants and transported to plants' cell walls. It helps strengthen cell walls, as a result, more tolerance of pests and diseases. It also has high cation exchange capacity (CEC) which helps improve soil�¢??s physical and chemical structure and soil's capacity to retain nutrients and slowly release them to plant's roots.�?� In soils, it helps loosen up hard soils resulting in better root growth.�?� Not only preventing loss of nutrients,�?� it also makes them more readily available to plants. Silicon also helps release fixed phosphate from soils resulting in better flowering. Silicon accumulated on leaves make them more shiny and help reduce transpiration rate. It can reduce water usage by as much as 30% resulting in more drought tolerant. Produce with silicon will taste better and stay fresh for longer time. Super Silicon Voga can be used in a variety of ways. Mix with chemical fertilizers, it will help prevent loss of nutrients and provide source of silicon to plants. Mix when spaying fungicides or insecticides, it will enhance and prolong the substance's efficacy. It can also be used to cure fungal diseases on trunks. Benefits: - Enhance efficacy of chemical fertilizers, prevent leaching - Prevent fungal and other diseases - Strengthen plants, improve resistance against pests and diseases - Enhance efficacy of chemical fungicides and pesticides�?� - Absorb toxins from soils, fruits, and vegetables Usage: - Mix with chemical fertilizer, manure or organic fertilizer before applying to soils. Use 1 kg of Super Voga for 50 kg of fertilizers. - Mix with small amount of water to make paste. Apply paste on plant's trunk infected by fungi. - Spread small amount around canopy to prevent root rot. - Mix 1 teaspoon of Super Voga in 20 liter spraying tank when spray fungicides or pesticides to increase their effectiveness - Mix 1 teaspoon Super Voga in 5 liter water. Use it to clean vegetables or fruits to clean chemical residues and help prolong freshness.
