Detail Information

What is Fulvic Acid？

Fulvic Acid is a naturally occurring, low-molecular-weight organic acid derived from the advanced decomposition of plant and animal matter through microbial action over centuries. It is the most active and bioavailable fraction of humic substances, characterized by a yellow to brown color and high water solubility. Unlike its larger cousin humic acid, fulvic acid boasts a small molecular size and a high density of oxygen-containing functional groups (e.g., carboxyl, phenolic), enabling it to readily chelate nutrients, enhance soil biology, and dramatically increase nutrient uptake and plant stress tolerance. It is a cornerstone of modern, sustainable agriculture as a powerful biostimulant and soil conditioner.

Core Features & Competitive Advantages

Ultra-High Bioactivity & Molecular Efficiency

· Balanced N-Ca-Mg Formulation: Combines fast-acting nitrate nitrogen for immediate growth, calcium for superior cell wall strength and fruit integrity, and magnesium as the core of chlorophyll for optimal photosynthesis. This synergy boosts overall plant health and yield potential far beyond single-nutrient fertilizers.

· High Oxygen-Containing Functional Groups: This unique structure gives fulvic acid exceptional cation exchange capacity (CEC) and chelating power, effectively unlocking and solubilizing bound nutrients in the soil, especially micronutrients like Fe, Zn, and Cu.

Triple-Action Performance Enhancer

· Biostimulant Effects: Stimulates seed germination, root development (increasing root mass by up to 30%), and enzyme activity, leading to stronger, more resilient plants.

· Nutrient Chelator & Carrier: Binds to both macro and micronutrients, forming organo-mineral complexes that are protected from soil fixation and are easily absorbed by plants, boosting fertilizer use efficiency by 20-40%.

· Soil Health Promoter: Enhances soil structure, increases microbial diversity and activity, and improves water retention, creating a thriving root zone environment.

Stability & Functionality

Chemical & Physical Stability
· High Chemical Stability: As a natural aromatic polymer, fulvic acid is chemically stable under normal storage and application conditions. It does not readily degrade or precipitate.

· Excellent Formulation Stability: Maintains stability in liquid concentrates (e.g., potassium fulvate solutions) and does not crystallize or settle, ensuring long shelf life and consistent performance in tank mixes.

Functional Efficacy in Soil-Plant System

· Systemic Action from Root to Shoot: Once absorbed, it acts as a cellular messenger and catalyst, improving respiration, photosynthesis, and protein synthesis throughout the plant.

· Stress Resilience Activator: Enhances plant production of antioxidants and osmolytes, improving tolerance to drought, salinity, heat, and heavy metal toxicity.

Applications & Solutions

1. Soil Drench for Rehabilitation & Microbial Health

Application: Apply 5-10 L/ha of fulvic acid via drip irrigation or drench to problem soils (e.g., compacted, saline, nutrient-depleted).

Benefit: Improves soil crumb structure, increases beneficial microbial populations, chelates toxic aluminum/sodium ions, and gradually rehabilitates soil health and productivity.

2.Fertilizer Efficiency Booster (Liquid Blending)
Application: Add 0.5-2 L/ton of liquid fulvic acid concentrate to NPK fertilizer solutions or irrigation water.

Benefit: Acts as a "nutrient taxi," reducing fertilizer fixation and leaching losses. It improves the mobility and uptake of applied nutrients, particularly phosphorus and micronutrients, allowing for potential fertilizer rate reduction.

3.Foliar Spray for Stress Mitigation & Qualit

Application: Apply a 0.1-0.3% fulvic acid solution as a foliar spray during key growth stages or periods of environmental stress.

Benefit: Provides rapid nutritional and biostimulant effects directly to leaves, improving chlorophyll content, reducing stress symptoms (e.g., wilting, scorch), and enhancing fruit sugar content, color, and uniformity.

FAQ

Q1: What is the difference between Fulvic Acid and Humic Acid? Which one should I use?

A: The main differences are molecular size and solubility. Fulvic Acid is small, soluble in both acid and alkali, and is best for direct plant uptake, foliar application, and chelating micronutrients. Humic Acid is larger, insoluble in acid, and excels at improving soil structure and long-term nutrient retention. For immediate plant response and nutrient efficiency, use Fulvic Acid. For long-term soil building, use Humic Acid. They are highly complementary and often used together.

Q2: Is there scientific proof that Fulvic Acid works?

A: Yes. Numerous peer-reviewed studies and field trials have documented its efficacy. Measurable benefits include increased root biomass, higher chlorophyll content (SPAD values), improved nutrient uptake (verified by tissue analysis), and enhanced yield under stress conditions. It is recognized as a legitimate plant biostimulant by agricultural authorities worldwide.

Q3: Is Fulvic Acid safe for organic farming?

A: Absolutely. High-quality, naturally extracted fulvic acid (and its potassium salt, potassium fulvate) is approved for use under major organic certification programs such as the USDA NOP, EU Organic, and OMRI. It is considered a natural soil amendment and plant strengthener.
