Humic Granule and Liquid
1. Humic Acid Powder And Granule – How to Use
🔹 a) Soil Drench (Dissolved in Water)
-
Dose per Acre:
➤ 2–5 kg per acre
(for moderate soils; increase up to 10 kg in degraded soils)
-
Dilution:
➤ Dissolve in 200–400 liters of water per acre
-
Application Method:
➤ Pour around root zones, or inject into drip system (after filtering) -
When to Apply:
-
Pre-planting
-
Early vegetative stage
-
During active root growth
​
🔹 b) Foliar Spray (Fine Filtered Solution)
-
Dose:
➤ 50–100 g powder per 100 liters of water
-
Method:
➤ Filter well and spray onto leaves
➤ Use 0.05%–0.1% solution (fine mist)
-
When:
➤ Morning or evening (avoid sunlight)
Granular Humic Acid – How to Use
🔹 Soil Broadcasting (Field Crops, Orchards)
-
Dose per Acre:
➤ 2 - 3 kg per acre
-
Method:
➤ Broadcast manually or with spreader
➤ Mix into top 10–15 cm of soil before planting or irrigation
🔹 Pit Application for Trees (e.g., Coconut, Mango, etc.)
-
Young Trees:
➤ 50–100 grams per tree
-
Mature Trees:
➤ 200–300 grams per tree
-
How:
➤ Apply in a circular trench or pit around the root zone (30–60 cm from trunk)
➤ Cover with soil and mulch
➤ Apply during monsoon or with irrigation
🔹 c) Mixing with Compost / Manure
-
How:
➤ Mix 5–10 kg of granular humic acid with 1 ton of compost or farmyard manure (FYM)
-
Why:
➤ Boosts microbial activity
➤ Increases nutrient-holding capacity (CEC)
Cautions When Using Humic Acid
-
Do not overdose: Using more than the recommended quantity will not give extra benefits and may cause imbalance in soil nutrients.
-
Always dilute properly in water before applying (whether soil drench, drip, or foliar spray).
-
Avoid spraying under hot midday sun – best time is early morning or late evening.
-
Do not mix humic acid with strong acidic or highly alkaline fertilizers/chemicals (it may reduce effectiveness).
-
Compatible with most fertilizers and micronutrients, but always do a jar test before mixing with pesticides or other products.
-
Store in a cool, dry place, away from direct sunlight and moisture.
-
Shake liquid formulations well before use to ensure uniform mixing.
-
For seed treatment – avoid soaking for too long (not more than 12 hours).
-
Humic improves efficiency of fertilizers – so you may reduce chemical fertilizer doses gradually, but do not stop them suddenly.
-
Keep away from children and animals; not for human or animal consumption.
