Humic substances are complex organic compounds essential for soil health and plant vitality. Among these, Humic acid and Fulvic acid are the most prominent, though they differ significantly in their properties and applications. NINGBO INNO PHARMCHEM CO.,LTD. helps to clarify these distinctions for your benefit.

Humic acid, identified by CAS 1415-93-6, represents the larger, less soluble fraction of humic substances. It is typically a dark, amorphous powder. Its molecular weight is generally higher, and it remains insoluble in water, especially under acidic conditions. Humic acid's primary role is as a long-term soil conditioner, improving soil structure, water retention, and nutrient-holding capacity over time.

Fulvic acid, on the other hand, is the smaller, more soluble fraction of humic substances. It remains soluble in water across a broader pH range. This solubility allows Fulvic acid to be more readily absorbed by plants, acting as a potent bio-stimulant and nutrient transporter. Its smaller molecular size enables it to penetrate plant tissues more easily, offering rapid benefits for plant growth and stress resistance.

While both are beneficial, their applications often differ. Humic acid is excellent for foundational soil improvement and long-term fertility. Fulvic acid is often preferred for applications requiring rapid nutrient delivery and enhanced plant uptake, such as foliar sprays or hydroponic systems. Understanding these differences is key when deciding which product to buy Humic acid or Fulvic acid.
