K-Humic is a highly concentrated humic acid powder soil conditioner extracted from natural leonardite ore. It is used to improve soil properties and prepare the root zone before and during planting, especially in poor, heavy or salt-affected soils. It improves soil aeration and increases the soil's capacity to hold water and nutrients, helping plants absorb fertilizers more effectively. Regular use results in stronger roots, more uniform growth and more stable yields.
Key Features:
- High-concentration soil conditioner based on naturally sourced humic acid
- Improves soil structure and helps break up heavy soils
- Increases the soil's capacity to retain water and nutrients
- Reduces the negative impact of salts in the root zone
- Raises the uptake efficiency of mineral and organic fertilizers
- Soluble powder, easy to apply with irrigation water
What It Does for Soil and Plants:
- Improves soil aeration and helps oxygen reach the roots
- Reduces nutrient loss through leaching
- Creates a healthy root environment for uniform plant growth
- Makes fertilization more efficient at the same application rates

- Dissolve the required amount thoroughly in water, then apply with irrigation water to ensure even distribution in the root zone.
Best Time to Apply:
- Before planting to improve the soil
- At the start of vegetative growth
- In salt-affected soils
- When plants respond poorly to fertilization
Important Notes:
- This product is a soil conditioner, not a direct-feeding fertilizer
- It helps reduce the effects of salinity but is not a direct salinity treatment
- Do not mix with strong acids or alkaline compounds
- Best used as part of an integrated fertilization program
Orkida Tip:
- If your soil is heavy, you feel your fertilizer is going to waste, or your plants are not benefiting well, K-Humic is the right first step. Once the soil and roots improve, every fertilizer you apply afterwards shows a clearer effect, and growth becomes stronger and more uniform.
