Humic acid/Potassium humate

Humic Acid is a cornerstone organic substance derived from the natural decomposition of plant and animal matter over millennia, forming a key component of soil humus. It is a complex mixture of large, organic molecules with a high molecular weight. While not directly soluble in acidic water, it becomes soluble in alkaline conditions, commonly processed into user-friendly forms like Potassium Humate. Humic Acid is not a direct fertilizer but a powerful soil conditioner and biostimulant. Its primary role is to fundamentally improve soil physics, chemistry, and biology, creating an optimal environment for root growth and unlocking the full potential of applied fertilizers. Think of it as renovating and revitalizing the soil itself to support sustainable, high-yield agriculture.

High Chemical Stability: As a complex natural polymer, it is highly stable in soil and resistant to rapid microbial degradation, ensuring its soil-conditioning effects are long-lasting.

Stable Across pH Ranges: While humic acid itself precipitates in acid, its beneficial effects on soil structure and nutrient retention are universal. Potassium Humate remains soluble and active across a broader pH range for flexible application.

Promotes Microbial Activity: Serves as a premium food source for beneficial soil bacteria and fungi, increasing their populations and activity, which drives nutrient cycling and suppresses soil-borne pathogens.

·Buffers Soil pH & Detoxifies: Helps moderate both acidic and alkaline soil conditions and can bind to heavy metals and pesticide residues, reducing their toxicity and bioavailability.

Application: Annually apply 50-200 kg/ha of Potassium Humate granules with basal fertilizers in greenhouses or high-intensity field crops.

Benefit: Counteracts soil fatigue and degradation caused by continuous monocropping, maintains soil vitality, reduces disease incidence, and supports consistent high yields.

Application: Coat or blend Humic Acid powder (1-3%) or Potassium Humate granules into compound (NPK) fertilizers or bulk blends.

Benefit: Significantly reduces nitrogen loss via volatilization and leaching, improves phosphorus and micronutrient availability, and elevates the overall efficiency and value of the fertilizer product.

Application: Use water-soluble Potassium Humate powder at 2-5 kg/ha per application through drip irrigation or in hydroponic nutrient tanks.

Benefit: Maintains a healthy rhizosphere environment in soilless systems, prevents root zone acidification and salt buildup, and stimulates root growth for better nutrient uptake.
