Voga organic fertilizer is made from active silicon and other high quality organic materials including manure, high quality rock phosphate, high magnesium dolomite and high potash ashes. It also includes other trace elements such as boron, zinc, iron and others.  Our silicon minerals contain high amount of plant available silicon or active silicon. It helps improve soil’s physical and chemical structure, increase soil’s beneficial microbes, and soil’s capacity to retain nutrients and slowly release them to plant’s roots.  Silicon when absorbed by plants helps improve plants’ resistance against pests and diseases.  Silicon on leaves make them more shiny and thus reflect more sunlight and reduce transpiration rate. It can reduce water usage by as much as 30% resulting in more drought tolerant.  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. Produce with silicon will taste better and stay fresh for longer time.


  • Contain macro-, micro-nutrients, trace elements and active silicon
  • High amount of organic matters and humus
  • Improve soil conditions, physical and chemical structure. Increase organic matter content in soils. Alleviate acid and saline soils.
  • Increase soil’s cation exchange capacity (CEC),  the capacity of soils to retain beneficial nutrients around plants’ roots. Reduce the use of chemical fertilizers.
  • Strengthen plant’s cell walls. Improve plants’ resistance against pests, fungal and other diseases. Suitable for organic farming.
  • More drought tolerant. Silicon accumulated on leaves help reduce water loss by up to 30%.
  • Help fruits and vegetables taste better and last longer


  • Apply 125-250 kg Voga fertilizer per acre
  • For short season crops, apply when seeding
  • For fruit trees and other trees, spread Voga organic fertilizer around canopy area

Benefits of Voga Silicon Fertilizer in Various Plants

ซิลิคอน กับต้นข้าว

Rice: Strengthen root systems, Increase root mass, larger shrub, no lodging, erect growth thus better light distribution within the canopy, better air circulation preventing from the accumulation of plant diseases and pests.  Silicon helps strengthen leaves resulting in better resistance to pest damage. Lacking of silicon in rice, corn, cucumber, or tobacco results in decrease of growth, plants losing more water, less resistance to powdery mildew in cucumbers, tomatoes, beans, and tobaccos. 

Sugarcane: Silicon helps loosen up hard soils, neutralize acid soils, prevent from toxicities of manganese and iron.  Silicon helps elongate and increase number of roots, increase sprouts. Leaves are more erect resulting in more sunlight reception, and better photosynthesis. Sugarcane can accumulate more sugar contents,thus higher sweetness. Sugar yield can be increased by 55%

Silicon promotes sugarcane tolerance capacity against stress from environment or organisms. It prevents leaf fleckle, sugarcane rust and ringspot. Silicon can improve soil physical and chemical properties better than calcium carbonate or dolomite do.

Cassava: Silicon improves soil structure, loosen up hard soils, as a result, cassava’s tubers can grow better, easier to harvest. Soil can better hold nutrients, less leaching. Help stabilize pH, since cassava is not tolerable of alkaline soils. Cuttings can root out more easily with a lot of roots. Roots can grow deeper into soils. More drought tolerant, better photo-synthesis, better starch accumulation. This results in high yielding by upto 100%. Silicon also strengthen cell walls, hence more tolerance to pests, aphids, and diseases.

Corn: Using silicon in growing sweet corn, no trunk rot and corn rust are found. Corn ears are nice without fungal spots. Ear sizes are large with 2 ears per kilogram. Corns are bright glossy yellow.

Rubber Tree: Silicon in rubber tree increases concentration of rubber juice by over 40%. It helps soften barks, prevent fungal infections, and prolong production life.  Rubber tree is more resistant to phytophthora infections. Rubber production can be increased by 20-30%

Oil Palm:  Silicon helps increase palm fruits, and also oil percentage.  Palm fruits production is increased by 20-30% while oil percentage is increased from 17% to 20%.  Oil palms are also more resistant to pests.

Coconut: In the past 2-5 years, Thailand experienced outbreak of coconut hispine beetle and coconut black-headed caterpillar due to prolonged drought. However, coconut orchards using silicon fertilizer were not affected.  An orchard in PrachubKirikan which has 598 coconut trees, normally has 1,600 coconuts per year with small sizes. A year after using silicon , production increased to 4, 000 coconuts with large A size.

Vegetables: Silicon support organic safe vegetable farming. It prevents pests, bacteria and fungal diseases. Also products have longer shelf life.
