Product Description
Iron Lignosulfonate (Fe LS) is a water-soluble anionic polyelectrolyte polymer derived from the sulfite pulping process of wood, complexed with iron (Fe). It serves as a biodegradable micronutrient fertilizer and industrial additive, enhancing soil fertility, nutrient availability, and acting as a dispersant or binder in various applications.
