High N

For your crops that need a nitrogen boost








Agroleaf® Liquid High N is a high-quality NPK liquid foliar fertilizer, with a higher proportion of nitrogen to prevent and/or correct any deficiency. Enriched with a consistent package of chelated trace elements, Liquid High N is especially designed for vegetative growth. Agroleaf® Liquid High N is powered by ICL’s one-of-a-kind F3 SurfActive technology, which increases the efficiency of each foliar application in three ways: for better spreading, adhesiveness, and retention. F3 works by lowering the surface tension of the droplets, so nutrients can be better spread over the leaves; this results in greater coverage and improved nutrient uptake. Plus, more nutrients are retained rather than running or bouncing off waxy leaves. What’s more, the F3 technology allows small nutrient deposits to form on the leaf surface, which are re-activated after rewetting; this prevents evaporation, thereby prolonging nutrition for improved foliar application.

  • Delivers nitrogen to crops for enhanced growth

  • Also contains chelated trace elements

  • Better spreading, adhesiveness, and retention

* Use lower dosages in lower volume of water/ha and higher dosages when the water volume is increased. Trail first on a small scale before changing the rate, or any other variables, As circumstances can differ and the application of our products is beyond our control, ICL cannot be held responsible for any adverse results.

  • ICL's F3 SurfActive Technology is a surfactant blend enhancing foliar nutrition efficiency, particularly beneficial when root uptake is compromised. This technology ensures improved nutrient spreading, adhesion, and retention on leaves, reducing runoff and maximizing nutrient availability. It can even reactivate under high humidity for sustained nourishment, optimizing foliar feeding in diverse crop conditions.
