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.
Technical profile
- 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.
- High solubility: the liquid formulation disperses readily in the application solution.
- 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.

Benefits and agronomic effects
Dual Micronutrient Correction
Provides zinc and manganese together to prevent or correct combined deficiencies with a single product.
Efficient Nutrient Uptake
The lignosulfonate complex helps maintain micronutrient availability and promotes efficient absorption by leaves and roots.
Improved Crop Performance
Supports balanced vegetative growth, dry matter accumulation and the physiological processes required for productive crops.
Yield and Quality Support
Helps crops express their yield potential while contributing to improved fruit development, size and colour.
Greater Nutrient-Use Efficiency
Supports the efficient use of applied nutrients, particularly where soil or environmental conditions restrict zinc and manganese availability.
Flexible Application
Suitable for both foliar and soil application across fruit trees, citrus, vegetables, extensive crops, olive trees and vineyards.

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.
