OmyaPro® Calcium

A new way of providing Calcium

OmyaPro® Calcium is a reactive and natural source of Calcium for foliar application. In the form of a wettable powder it can be easily applied to the crop. Due its ultrafine particles it forms a fine, evenly dispersed cover on the crop to supply the plant with Calcium.

OmyaPro® Calcium gives strength to your crop and fruits by providing a reserve of Calcium - a durable effect to cover crop demand when needed.
