Bentonite Humic Ball combines two soil-improving materials into a single granule: bentonite clay for water retention and cation exchange, and humic acid (derived from oxidised lignite or leonardite) for soil organic carbon enrichment and microbial activity stimulation. The result is a dual-action soil amendment that addresses both the physical and biological limitations of degraded agricultural soils.
The humic-bentonite blend is granulated on our pan granulators at a controlled ratio — typically 70:30 bentonite to humic material, adjustable based on buyer requirements. The granulation process binds the humic material into the bentonite matrix, creating a granule that can be broadcast with standard fertilizer spreading equipment and that releases humic compounds gradually as soil moisture breaks down the granule over 2–3 months.
Indian soils are critically deficient in organic carbon — over 60% of agricultural soils test below 0.5% organic carbon, the threshold for healthy soil function. Humic Ball directly addresses this by adding stable organic carbon in a form that resists rapid microbial decomposition, providing longer-lasting soil benefits than uncomposted organic matter.

Why Blend Bentonite with Humic Acid?
Humic acid alone is a fine powder that is difficult to handle, dusty to apply, and rapidly oxidised when exposed to sunlight and air at the soil surface. Bentonite alone improves soil physics but does not add organic carbon. By granulating the two together, we solve the handling problem (granules flow through spreading equipment without dust), protect the humic material from rapid oxidation (the bentonite matrix shields it), and deliver both benefits in a single field operation — the farmer does not need to apply bentonite and humic separately.
The slow-release mechanism is important: as soil moisture penetrates the granule, the bentonite swells and gradually exposes the humic material to soil microbes. This controlled release means the soil organic carbon benefit lasts 2–3 months rather than 2–3 weeks, matching the crop growth cycle more effectively.

Can you adjust the humic-to-bentonite ratio?
Yes. The standard ratio is 70:30 (bentonite:humic). We can produce 60:40 or 50:50 blends for buyers who want higher organic carbon content. Higher humic ratios increase the price per tonne and may slightly reduce granule hardness. MOQ for custom ratios is 10 MT.
Is Humic Ball suitable for all crops?
Humic Ball is suitable for field crops (wheat, rice, maize, cotton), horticultural crops (vegetables, fruit trees), and plantation crops (tea, coffee, sugarcane). The application rate varies by soil type and crop — sandy soils benefit most from the water retention component, while low-carbon soils benefit most from the humic component.
How should Humic Ball be stored?
Store in a dry, covered area away from direct sunlight and rain. The granules are stable for 12+ months when kept dry. Do not store in open yards during monsoon — moisture will cause premature swelling and granule breakdown.
