Agrocal powder is a natural, eco-friendly source of calcium and magnesium that increases soil fertility. In order to reach urban gardeners, it is now launched in small packages of 4 kg made from ecological, easily degradable paper, with a decorative single-colour print. Each package comes in a wooden box that is intended to be reused by gardeners. Different motivational sayings are carved into the box. Thanks to its stackability, this product becomes an independent entity which need not fight for a place on the shelves in the usually crowded agricultural supply stores.
