Ligno Mn
Highly Available Manganese Complexed with Natural Lignosulfonic Acid for Fast, Efficient Crop Nutrition
LIGNO Mn is a liquid manganese deficiency corrector formulated with 10% w/w manganese complexed by lignosulfonic acid, a natural chelating and complexing agent derived from lignin. Its highly soluble formulation keeps manganese in an available form, promoting efficient absorption and a rapid nutritional response after foliar or soil application.
The lignosulfonate complex provides high stability and helps distribute manganese evenly across the leaf surface. Its naturally low surface tension and hygroscopic properties support nutrient diffusion and penetration, including under relatively low-humidity conditions. By improving manganese availability, LIGNO Mn supports chlorophyll formation, photosynthesis, enzyme activation, nitrogen use, protein synthesis, germination, tillering, flowering and the development of healthy green tissues.
The product is suitable for preventing and correcting manganese deficiency in cereals, rice, maize, potatoes, legumes, oilseed crops, fruit crops, grapevines, tobacco, cotton and ornamental plants.

Origin and Certifications
LIGNO Mn is based on lignosulfonic acid, a natural lignin-derived biopolymer used as a complexing agent for micronutrients. This natural carrier increases manganese stability and helps maintain the nutrient in a water-soluble and plant-available form.
The product datasheet presents LIGNO Mn as a natural fertilizer and displays CE identification. Registration, certification status and permitted claims may vary depending on the destination market, so local agricultural regulations and the approved product label should always be consulted before use.

Features and Properties
LIGNO Mn is a highly soluble liquid manganese corrector containing 10% w/w manganese. Its liquid formulation facilitates dilution, tank preparation and homogeneous application through conventional foliar or soil nutrition systems.
The manganese is complexed with natural lignosulfonic acid. This complexing agent helps maintain the micronutrient in a stable and water-soluble form, improving its availability for plant uptake and limiting rapid nutrient immobilisation.
Lignosulfonates are hygroscopic biopolymers derived from lignin. Their ability to retain moisture around nutrient deposits can support manganese diffusion and penetration through the leaf surface, even when atmospheric humidity is relatively low.
The formulation also has naturally low surface tension. This characteristic promotes better spreading of the spray droplets and more uniform coverage of the treated leaf area, increasing contact between the nutrient solution and plant tissues.
Once absorbed, manganese contributes to several essential physiological processes. It activates numerous enzymes, participates in photosynthetic water-splitting reactions, supports chlorophyll synthesis and contributes to nitrogen metabolism and protein formation.
Adequate manganese nutrition also supports seed development, germination, early crop establishment, flowering, tillering and maturity. These functions are especially important in cereals and rice, where manganese availability can influence vegetative vigour, tiller development and stem stability.
Recommended Crops and Timing of Application
Cereals and Rice
Apply from the 3-leaf stage, particularly in fields with a history of manganese deficiency, high-pH soils or conditions that reduce micronutrient availability. Treatments support tillering, nitrogen efficiency, stem stability, vitality and winter hardiness.
Maize
Begin treatments from the 4-leaf stage. Early applications are particularly useful when cool soil conditions restrict root activity and manganese uptake.
Potatoes
Apply from the 6-leaf stage to support vegetative vitality, nitrogen efficiency and tuber skin quality.
Legumes
Begin from the 6-leaf stage, especially where cold conditions, restricted root activity or low manganese availability affect crop vitality.
Oilseed Rape and Sunflower
Apply from the 4-leaf stage. Programmes may support crop vigour, oil production and, in oilseed rape, winter hardiness.
Pome Fruit
Apply from red bud through to harvest, according to nutritional requirements. Treatments may support leaf activity, crop vitality and fruit colour development.
Soft Fruit
Begin at the start of shoot growth to support healthy foliage, nitrogen efficiency and vegetative vitality.
Citrus Fruit
Apply from white bud until harvest, adjusting the number of treatments to crop demand and leaf analysis.
Wine Grapes
Begin when inflorescences become visible. Repeat applications may support canopy vitality and manganese nutrition through important reproductive stages.
Tobacco and Cotton
Apply from the 4-leaf stage, especially when cold conditions limit early vegetative growth or nutrient uptake.
Ornamental Plants
Apply once plants have developed sufficient leaf mass to intercept and absorb the foliar spray effectively.
FAQ
What is LIGNO Mn?
LIGNO Mn is a highly soluble liquid fertilizer containing 10% w/w manganese complexed with natural lignosulfonic acid. It is designed to prevent and correct manganese deficiency in agricultural and ornamental crops.
What does manganese do in plants?
Manganese activates several enzymes and participates in chlorophyll synthesis, photosynthesis, nitrogen metabolism, protein formation, germination, tillering and reproductive development.
What are the typical symptoms of manganese deficiency?
Common symptoms include interveinal chlorosis, pale or mottled leaves, reduced photosynthetic activity, weak growth, poor tillering and lower crop vitality. Symptoms and their distribution vary by crop.
Can LIGNO Mn be used preventively?
Yes. Preventive applications are recommended in crops or soils with a known risk of manganese deficiency. Early treatment helps maintain adequate manganese nutrition before visible symptoms reduce crop performance.
Can it be applied as a corrective treatment?
Yes. Its highly soluble and stable formulation is suitable for rapid nutritional correction when manganese deficiency symptoms appear or when tissue analysis indicates insufficient manganese.
Is LIGNO Mn suitable for foliar application?
Yes. The lignosulfonate carrier promotes spreading, moisture retention and nutrient contact with the leaf surface. For general foliar use, apply 2–4 L/ha in at least 200 L of water.
Can it also be applied to the soil?
Yes. The datasheet identifies LIGNO Mn for both foliar and soil use. Soil rates should be adapted to crop requirements, soil characteristics, irrigation conditions and analytical results.
Why is lignosulfonic acid used in the formulation?
Lignosulfonic acid acts as a natural complexing agent. It stabilises manganese, helps keep it water-soluble and supports more efficient distribution and absorption.
Is LIGNO Mn compatible with other agricultural inputs?
It is compatible with most fertilizers and pesticides. A jar test should be performed before preparing any tank mixture that has not previously been tested.
When should treatments begin?
Timing depends on the crop. For example, applications can begin from the 3-leaf stage in cereals and rice, the 4-leaf stage in maize and oilseed crops, the 6-leaf stage in potatoes and legumes, red bud in pome fruit and visible inflorescences in wine grapes.
How many applications are recommended?
Depending on the crop, the programme may include between one and five applications. The number of treatments should be adjusted to crop demand, deficiency severity, growing conditions and the specific recommendations in the technical table.
Can LIGNO Mn be used in all crops?
Yes. The general recommendation covers all crops, while the datasheet also provides specific programmes for cereals, potatoes, legumes, maize, oilseed rape, sunflower, fruit crops, grapevines, tobacco, ornamental plants, cotton and rice.
