How to Use
Recommended Application Methods:- Soil Application (Pre-planting): Apply 10-20 kg per hectare, mixed with other fertilizers; Incorporate into soil during land preparation; For severe soil degradation: 20-30 kg per hectare
- Fertigation (Drip/Irrigation Systems): Dissolve 2-5 kg per hectare in irrigation water; Apply throughout the growing season; Use agitation in mixing tanks for best results
- Foliar Spray: Prepare 0.1-0.3% solution (1-3 g per liter); Apply during early morning or late afternoon; Spray interval: 15-20 days during active growth
- Seed Treatment: Prepare 0.5-1% solution for seed soaking; Soaking time: 8-12 hours; Dry seeds before planting
- Hydroponic Systems: Add 50-100 ppm to nutrient solutions; Monitor EC and pH regularly; Replace solution every 7-14 days
- Conduct soil testing for precise application rates
- Start with lower rates for initial applications
- Store prepared solutions for maximum 24 hours
- Avoid mixing with concentrated acidic solutions

Frequently Asked Questions
Q1: What's the difference between Potassium Humate and regular potassium fertilizers?
Unlike chemical potassium fertilizers that provide only K+, Potassium Humate delivers both readily available potassium AND organic humic substances that improve soil health, nutrient efficiency, and plant growth. It's a comprehensive soil amendment rather than just a nutrient source.
Q2: Is Potassium Humate suitable for organic farming?
Yes, when produced through physical extraction methods without synthetic chemicals, Potassium Humate is approved for organic agriculture under most international certification standards including USDA Organic, EU Organic, and COR.
Q3: How quickly will I see results after application?
Visible improvements in plant vigor and color often appear within 7-14 days. Soil structure improvements are more gradual and cumulative over multiple growing seasons. Maximum benefits are typically achieved with regular annual applications.
Q4: Can Potassium Humate be mixed with other fertilizers and pesticides?
Generally compatible with most common agricultural inputs. However:
- Always perform a small jar test before large-scale mixing
- Avoid mixing with highly acidic products (pH < 4)
- Mix with calcium-containing products may cause precipitation
- Add to spray tank last when tank-mixing
Q5: What is the ideal application timing?
Apply at key growth stages:
- Pre-planting for soil preparation
- Early vegetative stage for root development
- Flowering stage for fruit set
- Fruit development stage for quality enhancement
- Post-harvest for soil recovery
Q6: Does it work in all soil types?
Yes, but benefits are particularly noticeable in:
- Sandy soils: Improves water and nutrient retention
- Clay soils: Enhances structure and drainage
- Degraded soils: Speeds up rehabilitation
- Saline soils: Helps mitigate salt stress
