About Hauert MANNA
Hauert MANNA Düngerwerke GmbH is a fertilizer manufacturer based in Nuremberg that produces and distributes mineral, organic and organic-mineral fertilizers for the home & garden sector, professional needs (tree nurseries, ornamental plant cultivation, lawn and landscape gardening) as well as agriculture. Processing takes place on five in-house developed technologies: the compactor system for compacts (since 1985), the Granutec granulation developed in 2017 for dust-free mineral granulates, the Sphero system for organic granulates, two pellet mills for pellets, as well as processes for coated long-term fertilizers (Tardit) and urea condensates. Formulations are developed in the in-house laboratory and mixability tests with plant protection products are carried out. The company also offers field trials, plant analyses, expert advice and product training. Hauert MANNA is part of the owner-managed Hauert Group, now in its 12th generation; in 2025, around 59% of the raw materials used came from secondary sources.

Raw materials and technologies
Granutec granulation
Layer-by-layer buildup of ground mineral fertilizer formulation with water into round, dust-free granulates (2017).
Sphero technology
Production of cylindrical, dust-free granulates from organic and organic-mineral fertilizers.
Compactor (roll press)
Since 1985, production of low-dust mineral compacts by pressing into flakes, breaking and screening.
Pellet mill/pelletizing
Production of pellets for biological fertilizers.
Tardit MU (urea condensate)
Nitrogen long-term fertilizer made from methylene urea with microbiologically controlled release.
Coated granulates (resin coating)
Osmotically controlled nutrient release in long-term fertilizers.
Mineral fertilizers (NPK, nutrient salts)
Basis of the granulates, compacts and water-soluble multi-nutrient fertilizers.
Organic fertilizers
Plant and animal raw materials such as cattle manure, horn meal, horn chips and horn grit.
Organic-mineral fertilizers
Combination of both nutrient groups, produced on the compactor and Sphero systems.
