Calcium carbonate is widely used in agrochemical formulations as a cost-effective filler, carrier, and functional additive. Its fine particle size and high purity help improve the flowability, dispersion, and stability of pesticides, fertilizers, and seed treatment products. It acts as an inert carrier for active ingredients, ensuring uniform distribution and consistent performance. Also widely used in biofertilisers and biopesticide carriers for pH buffering and calcium nutrition.

Common questions about Calcium Carbonate in agro applications
Find detailed answers about specifications, applications, and technical details.
Calcium carbonate is abundantly available from natural limestone sources, relatively low in cost, chemically inert, non-toxic, and compatible with most agrochemical actives. These properties make it the most widely used filler and carrier in the industry.
Calcium carbonate's fine particle size and smooth particle morphology reduce inter-particle friction in powder blends, acting as a flow-promoting additive that prevents caking and bridging in storage and feeding equipment during agrochemical manufacturing.
Yes. Calcium carbonate is widely used as a carrier in biofertiliser formulations because its alkaline pH creates a favourable environment for many beneficial soil microorganisms. It also provides calcium nutrition and pH buffering in the soil.
Yes. Calcium carbonate is a source of calcium (Ca), an essential plant macronutrient critical for cell wall integrity, root development, and fruit quality. When used in agricultural formulations, it provides plant-available calcium while simultaneously improving soil pH.
For WP formulations, fine calcium carbonate grades with D50 of 5–15 microns and maximum particle size below 45 microns are preferred to ensure good dispersibility in water and uniform distribution of the active ingredient.
Yes. Fine calcium carbonate grades are used in seed treatment formulations as a carrier for fungicide and insecticide actives. Its inert nature does not harm seeds or seed germination, and its whiteness helps achieve good coating uniformity.
