Humic Acid Flakes
Humic acid flakes are a highly concentrated, 100% water-soluble organic soil conditioner, typically derived from leonardite or lignite, appearing as dark brown to black shiny particles. Used in agriculture to improve soil structure, increase microbial activity, and enhance nutrient uptake, these flakes are often rich in potassium and fulvic acid, promoting strong root development, enhanced water retention, and higher crop yields.
Key Characteristics & Composition
- Appearance:Dark brown to black flakes.
- Solubility:100% water-soluble, allowing for easy application via irrigation, foliar spray, or soil drenching.
- Composition:Contains high levels of organic matter, typically 95-98% humic acid/potassium humate.
- Nutrient Content:Often contains Potassium (K2O), with formulations commonly containing 5% to 12% K2O.
- Source:Derived from natural deposits like leonardite or oxidized lignite.
Key Benefits for Soil and Plants
- Soil Structure & Fertility:Improves soil aeration, water-holding capacity, and structure.
- Nutrient Efficiency:Acts as a natural chelating agent, binding to nutrients to prevent leaching and making nitrogen (N) and phosphorus (P) more available to plants.
- Root Development:Stimulates root growth and, in turn, plant resilience.
- Microbial Activity:Increases beneficial soil microbial life.
- Stress Resistance:Helps crops withstand environmental stresses such as drought or extreme temperatures.
Usage and Application
- Versatility:Compatible with most fertilizers, excluding strong acids.
- Application Methods:Can be used for soil applications (drip irrigation), seed dressing, or foliar spray (typically 0.5 g – 1 g per liter of water).
- Timing:Effective throughout the year but particularly recommended for spring and fall.
- Safety:Non-toxic and eco-friendly.
Typical Specifications
- pH:5 to 10 (alkaline).
- Moisture:<15%
- Storage:Should be stored in a cool, dry place
