ZAV Zinc Shield is a highly concentrated, fast-acting liquid formulation designed exclusively to prevent and rapidly correct Zinc deficiencies in all agricultural crops. Zinc is one of the most critical micro-elements in plant nutrition, yet it is frequently locked up in cold, wet, or high-pH calcareous soils. This specialized liquid shield bypasses soil limitations, delivering pure, readily available Zinc directly through the leaf cuticle or root system. It is an absolute necessity for or chard growers and broadacre farmers aiming to maximize early season growth and prevent irreversible yield loss.
