Compacted Potassium Humate Granules
Dry-Compacted Granules — No Binder, High Hardness, Built for Spreading
K₂O 2–5%
Solubility 80% min
Code JFHA-KHA-G
2–4 mm oval granule · 40% humic acid · 2–5% K₂O · 80% soluble · dry-compacted, no binder
Product Overview
Compacted Potassium Humate Granules are produced by roller compaction — the dry powder is passed between counter-rotating rolls under high pressure and the resulting sheet is broken and screened to a uniform 2–4 mm oval granule.
The distinguishing feature of roller compaction is that it is a dry process with no binder and no drying stage. Nothing is added to make the granule hold together; it holds together because the material has been compressed. Two practical consequences follow. The granule is hard and dense, so it survives bagging, blending, conveying and spreading without generating fines. And because nothing inert has been added, the analysis stays at 40% minimum humic acid with 2–5% K₂O and 80% minimum solubility.
The oval shape is worth noting too. It is not a sphere, and that is deliberate: the flat faces of a compacted granule give it better contact and mechanical interlock in a blend, which reduces the rolling and segregation you get with perfectly round particles during transport.
Compacted Potassium Humate Granules is the grade for base fertilizer application — drilled or broadcast ahead of or at sowing — and for blending with granular NPK.
Key Benefits
No binder, nothing added
Roller compaction is a dry process. The granule holds together under pressure alone, so no binder or inert material is introduced and the analysis stays where the raw material put it.
Hard, dense, low-fines granule
Compaction produces a harder particle than wet granulation. It survives bagging, conveying, blending and spreading with minimal breakdown.
Oval shape resists segregation
Flat faces give mechanical interlock in a blend, reducing the rolling and separation that round particles suffer during transport and handling.
40% humic acid with 2–5% K₂O
A solid granular analysis — 80% of the humic fraction is water soluble, so it releases into soil moisture rather than sitting inert.
Uniform 2–4 mm sizing
Consistent size gives an even spread pattern from a spinner or pneumatic spreader, and no fines to drift.
Low dust, clean handling
Essentially dust-free. Better working conditions and no product lost to wind at the spreader.

Form & Solubility
Form: uniform 2–4 mm black oval granules produced by roller compaction. Dense, hard, with slightly flattened faces from the compaction rolls. Dust-free.
In water: 80% minimum soluble. The granule breaks down and releases most of its humic fraction, leaving a small insoluble residue. Dissolve and filter if you are putting it through a fine system — but this is a soil-application grade, and that is where it is used.
Hardness: higher than a wet-granulated or disc-granulated particle. It survives mechanical handling well.
In the blender: the oval shape is an advantage here. It interlocks with granular NPK rather than rolling free, so the blend stays homogeneous through transport.

Soluble grades (powder, flakes, crystal) dissolve for fertigation, foliar and liquid production. Granular grades (compacted, round) are built for soil placement, blending and mechanised sowing. Every grade ships with a batch COA and the same heavy-metal declaration (Pb, As, Hg, Cd, Cr below detection, GB 18877).
Applications & Dosage
Built for base fertilizer and soil placement. Not a tank-dissolving grade:
| Application | How to use | Rate |
|---|---|---|
| Base fertilizer, mechanised sowing | Drill uniformly with the seeder and mix into soil at 10–15 cm depth. Avoid direct seed contact. | 750–1200 kg/ha |
| Base fertilizer, manual broadcasting | Spread evenly on the surface and plough in. Can be combined with other base fertilizers. | 600–1050 kg/ha |
| Blending with granular NPK | Blend with urea, MAP, DAP or MOP. The 2–4 mm oval matches standard granular sizing. | 5–15% of blend |
| Topdressing by root irrigation | Dissolve and dilute 500–800 times, stir, filter, and irrigate to the root zone. | 300–450 kg/ha per application |
| Orchard and perennial crops | Band or broadcast under the canopy during the active root period. | 500 g – 2 kg per plant |
| Pasture and broadacre | Broadcast for soil improvement across large areas. | 400–800 kg/ha |
Packaging & Storage
| Pack size | Description |
|---|---|
| 1 kg / 5 kg / 10 kg | Printed aluminium foil bag — retail and sample size |
| 20 kg / 25 kg | Woven PP bag with inner PE liner — standard export packing |
| 1000–1100 kg | Jumbo bag with discharge spout, 4 lifting loops |
| Custom | Private-label printed bag, OEM specification, retail sizes on request |
Storage: Store under cover in a cool, dry, ventilated place, on pallets and off bare concrete. The compacted granule is dense and low in surface area, so it stores well and resists moisture uptake better than a wet-granulated product.
Sustained wetting will still soften and consolidate the granules, so keep it dry. Under cover the material is stable for years. Shelf life: 24 months in original, unopened packaging.
Custom packaging, private-label printing and OEM specifications are available on request. Packaging photos are available in the product gallery.
Successful Cases
Grain cooperative, Kazakhstan
Drills compacted granules at roughly 900 kg/ha with a seeder on spring wheat across several thousand hectares. Chose the compacted grade over a disc-granulated alternative after trialling both: the harder granule generated noticeably less dust and fewer fines at the seeder, which matters when operators are loading all day.

Agriculture · Base Fertilizer
Blending plant, China
Blends at 10% with granular NPK for the domestic market. Reports better blend homogeneity with the oval granule than with a round one — the flat faces reduce rolling during transport, so the humic stays distributed rather than working down to the bottom of the bag.

Frequently Asked Questions
How is roller compaction different from disc granulation?
Roller compaction is dry and uses no binder: powder is pressed between rolls into a sheet, then broken and screened. Disc granulation is a wet process using a binder and a rotating pan, then drying. Compaction gives a harder, denser, oval particle with nothing added; disc granulation gives a rounder, softer particle. Both are legitimate — compaction suits hard handling and blending, disc granulation suits a rounder, more uniform appearance.
Why oval rather than round?
It is a consequence of the process rather than a design choice, but it has a real advantage: the flat faces interlock in a blend instead of rolling freely, so the material stays distributed during transport. If you want a genuinely spherical granule for appearance, look at our Round Granule grade.
Can I use this through drip irrigation?
It can be dissolved, diluted 500–800 times and applied by root irrigation after filtering — that is a listed application. It is not the grade to choose if your main route is fertigation through fine emitters; a fully soluble powder or flake is better suited and will not risk blocking.
What is the difference between this and Potassium Humate Round Granule?
Both are 2–4 mm at 40% humic acid, 2–5% K₂O and 80% solubility. Compacted is roller-compacted into an oval, binder-free, harder granule — better for hard handling and blending. Round Granule is a disc-granulated, genuinely spherical particle — better where roundness and uniformity of appearance matter. On specification they are close; choose on process and presentation.
Will it damage seed if drilled with it?
Avoid direct contact. Drill so that the granule is mixed into soil at 10–15 cm depth rather than placed directly with the seed. The material is alkaline at pH 9.0–10.0 and concentrated humate in direct contact with seed can affect germination — standard practice for any humic base fertilizer.
