Product Type
Organic manganese deficiency corrector with lignosulfonic acid
Ligno Mn
Highly soluble manganese deficiency corrector complexed with lignosulfonic acid for chlorophyll synthesis, nitrogen use, crop vitality and stress tolerance.
Ligno Mn is a highly soluble liquid manganese corrector complexed with lignosulfonic acid, a natural chelating agent that improves stability, distribution and nutrient absorption. Its low surface-tension properties support even coverage and penetration of manganese through the leaf surface.
Manganese is involved in chlorophyll synthesis, enzyme activation, nitrogen metabolism, protein synthesis, photosynthesis and reproductive development. Ligno Mn is designed for preventive and corrective programmes against manganese deficiency across a wide range of crops.

Key benefits and agronomic effects
- Prevents and corrects manganese deficiency.
- Supports chlorophyll synthesis and photosynthesis.
- Improves the use of available nitrogen.
- Supports protein synthesis, biomass formation and crop growth.
- Helps increase tolerance to low temperatures and frost.
- Supports enzyme activity, flowering, tillering, germination and early seed development.
How it works / Technical advantages
Ligno Mn uses lignosulfonic acid to stabilize manganese in a highly soluble and plant-available form. The lignin-based biopolymer is hygroscopic and has naturally low surface tension, helping micronutrients spread evenly across leaves and penetrate even under low-humidity conditions.
Manganese supports several key physiological processes, including chlorophyll formation, enzyme activation, nitrogen metabolism, protein synthesis, phosphorus and calcium availability, flowering, tillering and seed development.
Application rates and timing
Application Guidance: Apply preventively or when manganese demand is high, following the crop-specific programmes below. For the general all-crops programme, use 2-4 L/ha in at least 200 L water. The product is also designated for soil use, but no separate soil rates are provided.
