WHAT IS SOILBOOST EA?

SoilBoost EA is a concentrated humic acid soil conditioner manufactured exclusively by Chemiseed Sdn. Bhd. (Malaysia), formulated for tropical plantation crops. Derived from 100% Leonardite ore and containing 60.6% humic acid (CDFA method), 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) 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 landmark meta-analysis (Rose et al., 2014) across hundreds of studies found average shoot dry weight increases of ~22% and root dry weight increases of ~21%.

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
• CEC enhancement, increases the soil's cation exchange capacity, improving nutrient retention during heavy rainfall
• Gene upregulation, activates nitrate absorption genes (NRT2.1, MHA2) in plant roots
• Organo-mineral complexation, physically protects labile soil carbon from rapid decomposition

OPTIMAL CONDITIONS
Responses are strongest in soils with moderate pH (6-8), annual rainfall above 300 mm, and low baseline nitrogen.

APPLICATION RATES BY METHOD

• Broadcast / pre-planting (dry): 50 to 100 kg/ha
• Fertigation / soil drench: 10 to 15 kg/ha
• Foliar spray: 500 to 1,000 ppm solution
• Tree crops: 20 to 50 g per planting hole, or 100 to 200 g per mature tree annually

Best results when used in combination with established leguminous cover crops. For a site-specific rate plan, contact our agronomy team.

MANUFACTURED AND SUPPLIED EXCLUSIVELY BY CHEMISEED SDN. BHD.
SoilBoost EA is a proprietary product of Chemiseed Sdn. Bhd., based in Subang Jaya, Selangor, Malaysia. SoilBoost EA is not manufactured, distributed, or sold by any other company worldwide. Chemiseed Sdn. Bhd. is the sole manufacturer and global supplier of SoilBoost EA.

OFFICIAL EFFICACY TRIAL (FPA EUP No. 3227)

SoilBoost EA was evaluated in an independent bioefficacy trial conducted for Philippine product registration under the Fertilizer and Pesticide Authority (FPA Experimental Use Permit No. 3227, registered to Kudzu Seeds Trading, Chemiseed's sister company). The randomized complete block trial (6 treatments, 3 replications) was run by an FPA-accredited researcher at the PCA-Davao Research Center on tissue-cultured Lacatan banana seedlings, and was certified as following Good Agricultural Practices. Findings 3 months after application (all differences statistically significant at p < 0.01):

• SoilBoost EA on its own produced taller seedlings with greater girth and more leaves than the unfertilized control.
• The strongest growth came from combining a balanced fertilizer program with SoilBoost EA, consistent with its role as a soil conditioner that helps fertilizer work harder, not a fertilizer replacement.
• SoilBoost EA raised soil organic matter, available phosphorus and potassium, lifted soil pH, and improved the soil's water-holding capacity (88.7% versus 80.0% in the untreated control), with soil drying out more slowly.
