Dorogobuzh Develops New NPK Grades

Dorogobuzh (a member of Acron Group) has expanded the range of NPK complex mineral fertilisers produced at its facility in Smolensk region. With a macronutrient dosing unit and a micronutrient additive supply unit, the facility now produces twelve new NPK grades with varying levels of nitrogen, phosphorus, and potassium, as well as chlorine-free NP grades with the addition of sulphur, magnesium, and zinc. The new units, developed by Acron Engineering Research and Design Centre (a member of Acron Group), combine the existing continuous handling system for unloading and delivering raw materials for production with additional equipment: a magnesite pipeline, two feed bins, three weighing dispensers, a silo, and a dust suppression system. Magnesite (magnesium carbonate) and ammonium sulphate (ammonium salt of sulfuric acid) are the main raw materials used to add macronutrients to new NPK grades. Boron, zinc, copper, nickel, manganese, and other elements may be added as micronutrients to ensure healthy plant growth and development. They are used in the cultivation of cereals, legumes, oilseeds, berries, vegetables, and industrial and fodder crops. ‘Dorogobuzh is expanding the range of its NPK grades so that farmers can select the mineral nutrition system that works best for their conditions and crops’, said Alexander Karpechenkov, Head of Mineral Fertiliser Production at Dorogobuzh. ‘We are working toward obtaining state registration of the new grades, which will allow us to offer complex fertilisers optimal nutrients to domestic agricultural producers’.
