Humic Acid Liquid (also called liquid humic) is a dark liquid made by extracting natural humic and fulvic acids from high-grade leonardite ore and converting them into potassium salt form – no residue, no clogging in sprayers or drip systems. It is the most popular liquid organic soil conditioner and plant biostimulant today, used to fix poor soil (hard clay, sandy, acidic, saline, or compacted soil), stimulate massive root growth, help plants absorb fertilizer much better, and allow farmers to reduce chemical fertilizers by 15–30 % while maintaining or increasing yield.

When sprayed on leaves or applied to soil, plants stay dark green longer, resist pests and diseases better, tolerate drought, heat, cold, and salinity much more, and produce bigger, sweeter, better-colored fruits that store longer.

2. Main Benefits

• Quickly improves poor soil structure – makes hard clay soil softer and sandy soil hold more water.
• Increases cation exchange capacity (CEC) – soil holds nutrients longer, plants feed slowly and steadily.
• Strongly stimulates root growth – produces many white roots, bigger root system, better water and nutrient uptake.
• Acts as a natural chelator – helps iron, zinc, calcium, magnesium enter the plant easily, prevents yellow leaves and deficiencies.
• Reduces fertilizer waste – farmers can cut chemical fertilizer by 15–30% while maintaining or increasing yield.
• Helps plants resist drought, salinity, and extreme temperatures – stronger cell walls, less wilting.
• Greatly improves seed germination and early seedling strength when used for soaking or first sprays.
• Very safe – no leaf burn even when sprayed directly on tender leaves or young fruits.

3. Recommended Application

• Soil / drip / fertigation: 5–15 L/ha, repeat every 15–30 days
• Foliar spray: 300–600 ml per 1000 L water (0.5–1 L/ha)
• Seed treatment: dilute 1:300–1:500, soak 6–12 hours
• Root dip for transplanting: dilute 1:500

4. Compatibility

Mixes well with most liquid NPK, amino acids, seaweed, micronutrients, and pesticides. Avoid direct mixing with very strong acid products (pH < 4) or high free-calcium solutions. Always do a jar test for new combinations.

5. Storage & Shelf Life

• Store in cool, shaded place (5–40 °C)
• Do not freeze
• Shelf life: 36 months
• Shake well before use

6. Packaging

• 1 L, 5 L, 20 L HDPE bottles/drums 200 L plastic drums 1000 L IBC totes

7. Safety

Non-toxic, non-hazardous. Wear gloves and eye protection during handling. Rinse with water if contact occurs.
