Boost your crops with nitrogen-rich liquid










Stimulate vegetative growth with Agroleaf® Liquid Booster, our outstanding liquid foliar fertilizer. It supercharges your crops with nitrogen and comes with a full package of chelated trace elements. Booster contains 25% nitrogen, plus water-soluble trace amounts of magnesium oxide, iron, manganese, boron, copper, molybdenum, and zinc. The trick behind Agroleaf® Liquid Booster is ICL’s unrivalled F3 SurfActive technology, which we designed specifically to make each foliar application more efficient. It does so in three ways, improving spreading, adhesiveness, and retention. F3 technology reduces the surface tension of the droplets, allowing nutrients to distribute over the leaves more evenly for greater coverage and better nutrient uptake. It also retains more nutrients, preventing them from running or bouncing off waxy leaves. F3 aids nutrients in forming small deposits on the leaf surface, which are re-activated after rewetting; since this prevents evaporation, the nutrients stick around for longer, improving foliar application.

  • Delivers a punch of nitrogen to crops that need it

  • Packed with 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.
