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.

Important: SoilBoost EA is a soil conditioner. It is not a fungicide, pesticide, plant protection product, or standalone treatment for Fusarium TR4, Phytophthora, or any crop disease. It may support soil structure and root-zone conditions as part of a broader agronomy program, but disease management must follow local agronomist, regulatory, sanitation, drainage, and resistant-variety guidance.

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.

See the full trial, including the results table, chart and citation, on our SoilBoost EA banana field trial page (FPA EUP 3227), or the Evidence Hub. A trial summary is available on request.

Very heavy and thick
Style: 30 sqft
I purchased mini brands of sound ending and this is by far the heaviest sound deadening I've ever ordered. I'm not installed yet but I have a good feeling that is going to work exceptionally in blocking sound. If weight is a concern for you I would recommend a lighter product however if sound quality and a quiet ride is your priority this is the one for you.

Siless Hybrid 3-in-1 - Far Exceeded my Expectations!!!
Model: SLH20025
I recently installed the Siless Hybrid 3-in-1 sound deadening mat in my vehicle, and I’m genuinely impressed. For just $80 for 25 square feet, this product delivers performance that rivals materials costing twice as much — and with far less hassle. If you're on the fence......Just buy it! You will not be disappointed. Easy to Install: Unlike traditional sound deadening products that are stiff, sharp, and temperature-sensitive, this mat is soft, flexible, and easy to work with. I cut it cleanly with regular scissors and pressed it into tight spaces using just my fingers, so if in you don't have a roller or install tool, a good pair of scissors and your hands can get the job done. With other brands like Dynamat, the aluminum layer often leaves micro cuts on your hands and tears up your fingertips, but Siless does not due the acoustic layer being on top and above the aluminum layer that holds the butyl layer. So, it's very easy on your hands. Even in cooler temperatures (around 50°F), I had no trouble applying it but it goes on better heated. If warm outside, I would leave the entire box out in the sun for at least 30 minutes when it's warm or heats it's very pliable and easy to mold. Make sure its where you want it because once applied it's not ever falling off. and it became even more pliable and easy to mold. No heat gun, no mess — just straightforward application. I installed 40–50 square feet throughout the interior, covering everything except the headliner and the flooring forward of the rear seat. The difference in cabin noise is astonishing. I can turn my radio up concert loud with gut-punching bass, and from outside the car, it sounds like a factory sound system at mid volume. I was blown away by how well it contains sound — both inside out and outside in. My exhaust is pretty aggressive and now is barely audible from inside the cabin. While driving, it almost sounds like a stock factory setup. The Siless matting actually changed the driving experience and feels refined. If you're skeptical about sound deadening gimmicks, I get it, but this is the first product I've used and when I needed more, I went Stright to the 3 in 1 Hybrid matting and purchased it again. I love researching before buying and that's very uncommon for me to do. Note: Proper installation is key, and it does take time and patience. But if installed correctly and in the right places, it works better previously used from paint-on sound deadening to Dynamat. Update Nov, 2025 After using it this in 4 separate vehicles now. I feel the Siless’s 3 in 1 Hybrid has nailed it for best budget deadener that is better than dynamat extreme in performance and installation Protip: buy a roll of 2-3” aluminum tape and tape the seams. After trimming the edges tend to very sticky between the panels. I ran a strip of aluminum tape over the seems to create a better seal and true moisture I used it on four vehicles now and have I have not been paid to review and purchased every order myself. 3 in 1 Hybrid deadener by Siless is the best all around easy to apply sound deadner period!

Top quality
Model: SLH20025
This Siless Hybrid 3-in-1 sound deadening mat is easy to work with and feels high-quality. The butyl material is thick and pliable, making it simple to cut and fit into doors, floors, or panels. After installation, road noise and vibrations are noticeably reduced, and it also seems to improve the overall cabin feel. No bad smell. At 25 sq ft per roll, it’s a good value for anyone looking to dampen noise and improve car acoustics. Overall, a solid, effective option for automotive soundproofing. Used on a Fiesta ST.

Made a big improvement in cabin noise—highly recommend
Model: SLH20025
Siless Hybrid made a huge difference in reducing noise in the floor of my truck cabin. In some areas, there was basically just bare sheet metal between the inside and outside, so adding this really helped the truck feel more solid and noticeably quieter on the road. I used Kilmat on the doors, and honestly I wish I had used Siless Hybrid there too, but it was too late by the time I realized the difference. This material is very sticky, easy to cut, and simple to apply, which made the install pretty smooth. Just a heads-up: the tacky side gets messy and will bond to clothing really easily, so be careful during installation. Overall, I’d definitely buy it again—great product with real results.
