Poly-Feed™ Stim ARMOR

NPK fertilizers enriched with micro-nutrients and readily available silicon – for foliar application 

Positively affecting plant growth and health, silicon benefits for growing crops is well established. 
The silicon added to Poly-Feed™ Stim ARMOR formulae is in the form of fully soluble stabilized silicic acid, which ensures availability for plant uptake, and high efficiency. The silicone in Poly-Feed™ Stim ARMOR features neutral pH and it is free of sodium, which makes it superior to other silicon products.  Poly-Feed™ Stim ARMOR is so efficient, that it needs only small amount to strengthen the plant and to improves its growth.
