About this product
WHAT IS SOILBOOST EA?
SoilBoost EA is a concentrated humic acid soil conditioner manufactured exclusively by Chemiseed Sdn. Bhd., Malaysia (it is not sold by any other company). Formulated for tropical plantation crops. Derived from leonardite, it delivers active humic and fulvic molecules directly to the root zone, improving nutrient uptake efficiency, soil structure, and biological activity across oil palm, rubber, cacao, durian, and associated crops.
THE SCIENCE
A 2024 meta-analysis (Ma et al., Agronomy, MDPI) covering multiple crops and environments found that humic acid amendment delivers an average +12% crop yield uplift, +27% improvement in nitrogen use efficiency, and +17% increase in nitrogen uptake. A second landmark meta-analysis (Rose et al., 2014, Advances in Agronomy) across hundreds of studies found average shoot dry weight increases of ~22% and root dry weight increases of ~21% in response to humic substances, with stronger responses (~28%) under high-stress conditions.
HOW IT WORKS
SoilBoost EA operates through four proven biochemical pathways:
- Nutrient chelation, forms stable, water-soluble complexes with iron, zinc, copper, and other micronutrients, keeping them bioavailable rather than precipitated
- CEC enhancement, increases the soil's cation exchange capacity, preventing leaching of potassium, calcium, magnesium, and ammonium during heavy rainfall
- Gene upregulation, activates nitrate absorption genes (NRT2.1, MHA2) in plant roots, increasing nitrogen uptake efficiency at the cellular level
- Organo-mineral complexation, physically protects labile soil carbon from rapid decomposition, building long-term soil fertility
OPTIMAL CONDITIONS
Responses are strongest in soils with moderate pH (6-8), annual rainfall above 300 mm, and low baseline nitrogen, conditions that align precisely with tropical plantation soils across Southeast Asia.
APPLICATION
Soil drench, fertigation, or foliar application depending on crop stage and target outcome. Best results when used in combination with established leguminous cover crops, which provide the organic substrate for humic molecule activation.
EXCLUSIVE MANUFACTURER
SoilBoost EA is manufactured exclusively by Chemiseed Sdn. Bhd., Malaysia. Kudzu Seeds Trading, its sister company, offers SoilBoost EA to its markets. SoilBoost EA is not available from any other supplier.
GLOBAL AVAILABILITY

Is this right for your site?
Where this fits
A humic-acid soil conditioner that improves soil structure and biology alongside your fertilizer program.
Well suited for
- Improving soil structure, aeration, and microbial activity
- Conditioning acidic tropical soils
- Nursery media and field soil preparation
- Complementing a fertilizer program, not replacing it
Less suitable for
- Use as a standalone NPK fertilizer (it conditions soil, it is not a complete nutrient source)
- Application beyond the recommended rate
Not sure it fits your conditions? Send your crop, area, and site details and our team will advise on suitability before you order.
Documents available
Technical Data Sheet (TDS), Certificate of Analysis (COA) with composition data, Safety Data Sheet (SDS), and product registration documents are available on request.
Limitations and site considerations
Product performance depends on soil type, existing organic matter, application rate, moisture conditions, and crop system. SoilBoost EA and Hyacinth Plus are soil conditioners, not complete fertilizers. Follow recommended application rates and consult us for site-specific guidance.
