Flourish Nitrogen™ Is A Concentrated (15,000 Mg/L) Blend Of Nitrogen Sources. It Provides Nitrogen In Both The Nitrate Form And The Plant–Preferred Ammonium Form. However, No Free Ammonia Is Released Because The Ammonium In Flourish Nitrogen™ Is Complexed And Unavailable Until Utilized By The Plants. Ammonium Becomes Available After Conversion Of Urea (Carbamide). Flourish Nitrogen™ Also Provides Nitrate For Those Plants That Can Readily Utilize Nitrate As Well. For Maximum Benefit, Use With Flourish Phosphorus™ And Flourish Potassium™. Flourish Nitrogen™ Is Safe For Invertebrates Such As Shrimp. Sizes: 100 Ml, 250 Ml, 500 Ml, 2 L, 4 L.
