Organic Bentonite Granules for Certified Organic Farming — Chemical-Free Soil Conditioning

Introduction

Certified organic farmers work under a strict rule: inputs must be natural and free of prohibited synthetic chemicals. Organic bentonite granules meet that requirement — a natural clay soil conditioner processed by purely physical means, with no chemical additives. This guide explains how organic-grade bentonite conditions soil, why the "no additives" specification matters, and how it fits an organic programme.

What Makes Bentonite Granules "Organic Grade"

The key is processing, not a different mineral. Radhe Enterprise organic bentonite granules specify:

• Montmorillonite content > 75% and cation exchange capacity 60–80 meq/100g.
• Chemical additives: none — no synthetic binders, activators, or coatings.
• Organic-compliant: yes — processed only by physical methods (crushing, screening, granulation).
• Particle size 2–6 mm, pH 8.0–10.0.

Because it is simply mined clay, processed physically, high-purity bentonite is well suited to organic-input use — but growers should always confirm acceptance with their own certifier for their specific standard.

How Bentonite Conditions Soil

Bentonite improves soil physically and chemically, which is why it is valued as an organic conditioner:

• Water retention: montmorillonite holds water in the root zone, reducing irrigation stress — a major benefit on sandy soils.
• Cation exchange capacity: the clay holds nutrient cations (K⁺, Ca²⁺, Mg²⁺, NH₄⁺) against leaching, improving the efficiency of organic fertilizers and compost.
• Structure and body: it gives light, leaching-prone soils the body to retain moisture and nutrients.
• Nutrient buffering: by holding and gradually releasing nutrients, it smooths the feast-or-famine cycle that pure organic inputs can create.

Note that bentonite conditions soil and holds nutrients but does correct acidity — for pH and calcium/magnesium, organic growers use dolomite (see ).
