Nutri Gold K 4-21-28


Nutri Gold K (4-21-28) is an innovation in liquid foliar fertilizer. Produced using Potassium in Organic salt (Acetate) form, which is a natural plant metabolite. This Potassium form, plants can easily absorb through the leaves, faster than other forms of Potassium fertilizers that are common in the market. This is due to the smaller molecular size. Nutri Gold K (4-21-28) is also chloride-free and has a very low salt index. Therefore, it is very safe when applied using foliar fertilizer. When applied by foliar spray, there is no burning effect on the leaves and soft plant tissues.


  • Increase starch accumulation to promote flowering and flower bud formation
  • Increases yield, promotes translocation of starch and sugars
  • Maintains quality parameters such as size, shape, color, taste, and shelf life


  • Absorbs much faster than other forms of Potassium fertilizers due to its smaller molecular size.
  • Safe for crops due to low salt index.
  • Rapid absorption rate in the leaves, especially during dry weather and strong sunlight.
  • Reduces rain-washing due to rapid absorption
