Carrier loading and release
Pesticide granules and powders must hold the active ingredient without caking or degradation, then release it predictably. Carriers with uneven sorptivity or particle size cause dosing errors in the field.

Overview
Minerals engineered for agriculture
Agricultural minerals do quiet but essential work in crop inputs, from the granule a farmer spreads to the powder a formulator blends. Obsidian Minerals supplies attapulgite carriers, bentonite binders, dolomite and diatomaceous earth to agrochemical formulators, fertiliser producers and blenders.
Each mineral plays a distinct role. The needle-shaped particles and high sorptive capacity of attapulgite make it a carrier and diluent for pesticide granules and wettable powders, holding active ingredients until they are released in the field. Bentonite swells and binds, so it is used to granulate and harden fertiliser products such as bentonite-sulphur pastilles and compound fertiliser granules, improving crush strength and dust control. Dolomite supplies both calcium and magnesium and neutralises acidity, so it is used to correct soil pH and as a magnesium source in blends. Diatomaceous earth is a porous, siliceous material used as a carrier, as an anti-caking agent and in pest control applications, subject to local regulatory approval.
All products are made under ISO 9001 certified processes, tested in an NABL-accredited laboratory and supplied with a TDS, MSDS/SDS and batch CoA. Particle sizes, granule mesh ranges and packaging can be adapted to formulation and blending plants. Customers should verify the regulatory status of each input in their market, and samples are available for trial batches.
Problems we help solve
Granule strength and dust
Fertiliser granules that break down in handling create dust, segregation and uneven spreading. Binders are needed that improve crush strength without hindering dispersion in the soil.
Soil acidity and magnesium supply
Acidic soils limit nutrient availability, and intensive cropping depletes magnesium. Growers and blenders need a liming material that supplies calcium and magnesium in a controlled particle size.
Free flow and storage stability
Hygroscopic fertilisers and agrochemical powders cake in humid storage. Mineral anti-caking agents and conditioners help keep products flowing through blenders, bagging lines and spreaders in the field.
Recommended products for Agriculture
Attapulgite
Attapulgite Pesticide Carrier Grade

Bentonite
Fertiliser Binder Grade Bentonite
Swelling bentonite used to bind fertiliser granules and bentonite-sulphur pastilles, improving crush strength and reducing dust, then dispersing in moist soil to release the nutrients.
View grade specs
Bentonite
Calcium Bentonite
Calcium bentonite used as a filler, carrier and absorbent in agrochemical and fertiliser formulations where a lower-swelling clay is preferred by the formulator for processing or release reasons.

Why is attapulgite used as a pesticide carrier?
Attapulgite has a needle-like crystal structure with a high surface area and strong sorptive capacity, so it can absorb liquid active ingredients while remaining free-flowing. It is chemically stable with many actives and can be supplied as granules of a defined mesh range or as powder. Compatibility with each active should still be confirmed in stability tests.
How does bentonite work as a fertiliser binder?
Bentonite swells when wetted and forms a strong bond between particles as the granule dries, improving crush strength and reducing dust in handling. In bentonite-sulphur products, the clay also helps the pastille break apart in moist soil, exposing fine sulphur particles. Binder dosage depends on the granulation process and target granule strength.
Is dolomite suitable for correcting soil pH?
Dolomite is widely used as a liming material because it neutralises soil acidity and supplies both calcium and magnesium. Application rates depend on soil type, current pH, target pH and crop, so they should be based on soil testing and local agronomic advice. Finer particle sizes generally react faster in the soil.
Are your agricultural grades approved for use in my country?
Regulatory requirements for carriers, fertiliser inputs and pest control products differ between countries and uses, so approval cannot be assumed. We supply a Technical Data Sheet, MSDS/SDS and batch Certificate of Analysis to support your registration or compliance work, and customers should verify suitability and approval status before use.
