SoilBoost EA vs Biofertiliser (Pupuk Hayati): What Is the Difference?

A clear B2B explainer on humic acid soil conditioners (pembenah tanah) versus living microbial inoculants (pupuk hayati), by Chemiseed Sdn. Bhd.

Short answer: SoilBoost EA is a humic acid soil conditioner (pembenah tanah), not a biofertiliser (pupuk hayati). A biofertiliser contains living microbial inoculants such as Rhizobium, mycorrhizae, or PGPR that are added to the soil. SoilBoost EA contains no live microbe inoculants. It is a Leonardite-derived humic acid that improves soil structure and cation exchange capacity (CEC) and supports the soil's existing microbial community and nutrient uptake. The two products work on different parts of the system, and they can be used together.
At a glance
  • SoilBoost EA: humic acid soil conditioner, 60.6% humic acid (CDFA method), pH 3.84, 0.45% sulfur, Leonardite-derived. Manufactured exclusively by Chemiseed Sdn. Bhd. (Malaysia).
  • Biofertiliser / pupuk hayati: a product whose active ingredient is living microorganisms (for example Rhizobium, mycorrhizae, PGPR).
  • Key distinction: SoilBoost EA does not contain live microbes. It improves the soil environment; a biofertiliser adds organisms to that environment.
  • Application (SoilBoost EA): broadcast 50 to 100 kg/ha, or drench 10 to 15 kg/ha.
  • Not: a fertiliser substitute, and not a disease treatment.

What Is a Biofertiliser (Pupuk Hayati)?

A biofertiliser, or pupuk hayati, is a product whose function depends on living microorganisms. Common examples include nitrogen-fixing bacteria such as Rhizobium, mycorrhizal fungi that extend a plant's effective root area, and plant growth-promoting rhizobacteria (PGPR). When applied, these organisms colonise the soil or the root zone and carry out a biological function: fixing atmospheric nitrogen, improving phosphorus availability, or producing growth-related compounds.

Because the active ingredient is alive, biofertilisers depend on viability. Storage conditions, shelf life, soil temperature, moisture, and compatibility with existing soil organisms all affect whether the inoculant establishes and performs.

What Is SoilBoost EA (Humic Acid Soil Conditioner)?

SoilBoost EA is a soil conditioner (pembenah tanah) based on humic acid derived from Leonardite. It is not alive and it contains no microbial inoculants. Its role is to improve the soil itself: humic acid raises cation exchange capacity, helps hold and deliver nutrients, supports better soil structure, and chelates micronutrients so they remain available to roots.

By improving the soil environment, SoilBoost EA supports the soil's existing microbial community and the plant's nutrient uptake. This is an indirect, environmental effect. It is not the same as adding microbes. SoilBoost EA does not introduce Rhizobium, mycorrhizae, PGPR, or any other organism into the soil.

Side-by-Side Comparison

Factor Biofertiliser (Pupuk Hayati) SoilBoost EA (Pembenah Tanah)
Active ingredient Living microorganisms (Rhizobium, mycorrhizae, PGPR) Humic acid from Leonardite (not alive)
Contains live microbes? Yes, that is the product No
Primary action Adds organisms that perform a biological function in soil or roots Improves soil structure, CEC, and nutrient retention
Effect on microbes Introduces new organisms Supports the soil's existing microbial community by improving its environment
Supplies nutrients directly? Indirectly, via biological activity (for example N fixation) No, it improves nutrient delivery and uptake
Viability-dependent? Yes, depends on living organisms surviving No, it is a stable mineral-organic input
Category Pupuk hayati (biofertiliser) Pembenah tanah (soil conditioner)

When Do You Use Each?

Use a biofertiliser when

You want to introduce or boost a specific biological function, for example inoculating legumes with compatible Rhizobium to support nitrogen fixation, or applying mycorrhizae to improve phosphorus access. The goal is to add organisms that are missing or insufficient in the soil.

Use SoilBoost EA when

You want to improve the soil environment itself: raise CEC, improve nutrient use efficiency, support structure on tired or low-organic-matter soils, and create conditions where roots and the existing microbial community can function better. Broadcast at 50 to 100 kg/ha or drench at 10 to 15 kg/ha.

Use them together when

You want both effects. Humic acid can improve the soil environment that inoculants and roots live in, which is why a soil conditioner and a biofertiliser are often complementary rather than competing. SoilBoost EA does not contain the microbes, but it helps create conditions in which an applied inoculant and the existing soil biology can establish and work.

Important: what SoilBoost EA is not

SoilBoost EA is not a biofertiliser and does not contain live microbial inoculants. Any claim that it supplies Rhizobium, mycorrhizae, or PGPR would be incorrect.

SoilBoost EA is not a fertiliser substitute. It improves the efficiency of your fertiliser programme but does not supply nitrogen, phosphorus, or potassium at agronomic rates.

SoilBoost EA is not a disease treatment. It supports soil and plant resilience by improving the growing environment; it is not applied to control or cure any disease.

Frequently Asked Questions

Is SoilBoost EA a biofertiliser (pupuk hayati)?
No. SoilBoost EA is a humic acid soil conditioner (pembenah tanah). A biofertiliser contains living microbial inoculants such as Rhizobium, mycorrhizae, or PGPR. SoilBoost EA contains no live microbes. It is Leonardite-derived humic acid that improves soil structure, cation exchange capacity, and nutrient uptake.
Does SoilBoost EA contain Rhizobium, mycorrhizae, or PGPR?
No. SoilBoost EA does not contain any microbial inoculant. It supports the soil's existing microbial community indirectly by improving the soil environment, but it does not add organisms to the soil.
Can I use SoilBoost EA together with a biofertiliser?
Yes. They address different parts of the system and are often complementary. A biofertiliser adds organisms; SoilBoost EA improves the soil environment those organisms and the plant roots live in. Follow each product's own application guidance.
Does SoilBoost EA replace my fertiliser?
No. SoilBoost EA is not a fertiliser substitute. It improves nutrient use efficiency and soil condition, but you still apply fertiliser to supply nitrogen, phosphorus, and potassium. SoilBoost EA helps your fertiliser work more efficiently.
How do I apply SoilBoost EA?
Broadcast at 50 to 100 kg/ha, or drench at 10 to 15 kg/ha, depending on your crop and soil condition. For a tailored rate for Indonesian conditions, contact Windhi, our Indonesia representative.
