LIGNO Zn-Mn
Dual Zinc and Manganese Corrector for Efficient Foliar and Soil Nutrition
LIGNO Zn-Mn is a dual-action micronutrient corrector containing 4.5% manganese and 4.5% zinc. Its natural-origin lignosulfonate complex promotes nutrient availability and facilitates efficient uptake through both leaves and roots.
The product is designed for crops affected by zinc and manganese deficiencies or grown under conditions that restrict micronutrient availability. These include alkaline or high-pH soils, low temperatures, nutrient antagonisms, limited soil reserves and intensive production systems with high nutritional demand.
By supplying two essential micronutrients in a single application, LIGNO Zn-Mn supports enzyme activity, chlorophyll formation, protein synthesis, nitrate metabolism and normal plant growth. Its flexible formulation can be applied foliarly or through the soil across a wide range of agricultural crops.

Origin and Certifications
LIGNO Zn-Mn is formulated with lignosulfonic acid, a biodegradable organic polymer of natural origin used as a micronutrient-complexing agent. This technology forms part of Tangel Agro’s LIGNO range, developed to provide efficient crop nutrition with a reduced environmental impact.
The technical datasheet presents LIGNO Zn-Mn as an EU-origin fertilizer and displays CE and EU organic-production marks. Certification status, permitted uses and registration requirements may vary between markets, so the current commercial label and applicable local regulations should always be consulted before use.

Technical Advantages
- Balanced dual formulation: equal concentrations of manganese and zinc simplify the correction of combined deficiencies.
- Natural lignosulfonate complex: the micronutrients are complexed with lignosulfonic acid to support their availability and assimilation.

- Foliar and root uptake: it can be applied directly to foliage or through the soil according to crop requirements.
- Broad crop compatibility: suitable for use in a wide range of horticultural, fruit, vineyard and extensive cropping systems.
- Targeted correction under limiting conditions: especially useful when low temperatures, high soil pH, antagonisms or depleted soil reserves reduce micronutrient uptake.
- Biodegradable carrier: lignosulfonic acid is a natural-origin organic polymer with a favourable environmental profile.
- Operational efficiency: combines two essential micronutrients in one application, reducing the need for separate zinc and manganese treatments.

Features and Properties
LIGNO Zn-Mn is a concentrated liquid micronutrient corrector containing 4.5% manganese (Mn) and 4.5% zinc (Zn). Both micronutrients are complexed with lignosulfonic acid, a natural-origin compound that promotes nutrient availability and facilitates assimilation by the crop.
Manganese participates in enzyme activity, protein synthesis and processes associated with normal plant growth. An adequate manganese supply is also important for photosynthetic metabolism and the efficient functioning of plant tissues.
Zinc contributes to enzyme activation, chlorophyll formation, nitrate reduction and protein synthesis. It is required for healthy vegetative development and for the metabolic processes that influence crop establishment, growth and productivity.
The combined formulation is especially valuable when both micronutrients become poorly available. Such situations frequently occur in alkaline soils, during periods of low temperature, in the presence of nutrient antagonisms or where intensive crop production has reduced soil reserves.
Its high solubility and liquid format make LIGNO Zn-Mn suitable for precise foliar treatments and soil applications. The use of biodegradable lignosulfonic acid as the complexing agent also supports efficient micronutrient delivery with a reduced environmental impact.
Recommended Crops and Timing of Application
LIGNO Zn-Mn is recommended for fruit trees, citrus, vegetables, extensive crops, maize, flax, olive trees, vines and any crop susceptible to zinc or manganese deficiency.
In fruit crops, the most important application periods include pre-flowering, fruit set, fruit development and post-harvest recovery. In citrus, treatments should coincide with spring and summer flushes, once the new shoots have developed sufficient leaf area.
For vegetables and extensive crops, begin applications after good root establishment or during the early stages of active vegetative growth. In maize, the 5-6-leaf stage is a particularly suitable reference point.
In vineyards, treatments can be distributed from inflorescence development to veraison. In olive trees, applications are recommended at spring growth and again during fruit fattening.
Preventive applications should be made before visible deficiency symptoms become severe, particularly in high-pH soils or during cool periods. Corrective treatments should begin as soon as symptoms or analytical results confirm insufficient zinc or manganese nutrition.
FAQ
What is LIGNO Zn-Mn?
LIGNO Zn-Mn is a liquid micronutrient fertilizer containing 4.5% zinc and 4.5% manganese complexed with natural-origin lignosulfonic acid.
What is LIGNO Zn-Mn used for?
It is used to prevent and correct zinc and manganese deficiencies in agricultural crops through foliar or soil application.
Why does the product contain both zinc and manganese?
Deficiencies of these micronutrients can occur simultaneously, particularly in high-pH soils or under conditions that restrict nutrient uptake. A combined formulation allows both deficiencies to be addressed in one application.
How does lignosulfonic acid improve the formulation?
Lignosulfonic acid acts as a natural complexing agent. It helps keep zinc and manganese available in the application solution and supports their efficient assimilation by leaves and roots.
Can LIGNO Zn-Mn be applied to all crops?
The technical datasheet recommends it for all crops, with specific programmes for fruit trees, citrus, extensive crops, vegetables, olive trees and vineyards. The current commercial label and local regulations should always be checked.
What is the recommended foliar dose?
The general foliar dose is 300-500 cc/hL per application. Crop-specific recommendations range from 300 to 400 cc/hL.
What is the recommended soil dose?
Apply 4-8 L/ha, normally in 2-4 applications separated by intervals of 15-20 days.
When should the product be applied?
Apply preventively during periods of high micronutrient demand or correctively when visual symptoms, plant analysis or soil analysis indicate a zinc or manganese deficiency.
Under which conditions are deficiencies more likely?
The risk increases in high-pH soils, during low temperatures, where nutrient antagonisms occur, in soils with low micronutrient reserves and under intensive production conditions.
Can LIGNO Zn-Mn be mixed with other products?
A preliminary compatibility test should always be performed before mixing it with other fertilizers or crop-protection products. Follow the instructions on the current label.
Should it be applied during rain, frost or drought?
No. Avoid treatment during extreme drought, excessive humidity, frost or rain, as well as when these conditions are forecast shortly after application.
