Organic Carbon Division of GREEN AGROCHEM
Organic carbon fertilizers for depleted soils
Carbon fertilizers built on humic and lignin-based carbon to return stable organic carbon to intensively farmed land, with soil-carbon knowledge for growers, distributors and fertilizer makers.

Why soil carbon
Soil organic carbon is the fertility that intensive farming loses first
Soil organic carbon (SOC) is the carbon held in humified organic matter. It holds water, buffers pH, keeps nutrients in reach of roots and anchors soil structure season after season. Continuous cropping burns it down faster than residues can replace it.
- ~55%Share of soil organic matter that is carbon (about 50–58%), the factor labs use to convert SOM to SOC.
- CECHumified carbon raises cation exchange capacity, so applied nutrients stay in the root zone instead of leaching.
- YearsStable, humified carbon persists for years to decades, unlike fresh residue that mineralises within a season.
Carbon fertilizers
Four ways to put carbon back into the soil
Humic-acid organic fertilizers for base application, top dressing, fertigation and worn-out soils. Organic matter or humic acid ≥ 45% with NPK ≥ 5%.
Top dressing
Carbon Base Plus
Humic-acid-rich top dressing that keeps nutrients available in the middle and late growth stages.
HA ≥ 45% · NPK ≥ 5%25 kg
Fertigation
Organic Carbon Fertigation
Soluble organic carbon for drip and flood irrigation, with fulvic acid.
OM ≥ 45% · NPK ≥ 5%25 kg
Soil improver
Carbon Guard
For fields with replant problems and continuous-cropping stress, used with base fertilizer.
OM ≥ 45% · NPK ≥ 5%25 kg
Produced to the Chinese organic fertilizer standard NY 525. Dosage depends on crop and soil; see each product page.
Raw materials
The carbon behind the fertilizers
Three families of natural carbon supply the humified and soluble carbon in our fertilizers. Each is also available as an ingredient for fertilizer makers.
Lignin-based carbon
Lignosulfonates and lignohumates from wood lignin: binders, dispersants and a soluble carbon source for granules and liquids.
Humic acids
Leonardite- and lignite-derived humic acid and its salts: the stable, humified carbon fraction.
Fulvic acids
Low-molecular-weight, fully soluble carbon for foliar sprays, fertigation and chelated nutrients.
Co-formulants: amino acids and seaweed extract for biostimulant blends.

FAQ
Common questions
What is a carbon fertilizer?
An organic fertilizer whose main job is to return stable organic carbon to the soil, here from humic acid and lignin-based carbon, combined with a modest NPK content.
How is soil organic carbon different from organic matter?
Soil organic matter is all organic material in the soil. Soil organic carbon is the carbon inside it, roughly 50–58% of organic matter by weight.
Can I buy the humic or fulvic raw materials separately?
Yes. Humic acid, humates, fulvic acids and lignin-based ingredients are supplied to fertilizer makers with TDS, SDS and COA.
Do you send samples for trials?
Yes. Tell us the crop, soil and current programme and we suggest a product and send samples.
