Product Type
Dual zinc and manganese deficiency corrector with lignosulfonic acid
LIGNO Zn-Mn
Highly soluble dual zinc and manganese corrector complexed with lignosulfonic acid for rapid uptake and prevention of Zn and Mn deficiencies.
LIGNO Zn-Mn is a highly soluble liquid corrector supplying both zinc and manganese, complexed with lignosulfonic acid. It is designed for foliar and soil application to prevent and correct deficiencies of both micronutrients across a wide range of crops.
The formulation is especially relevant where Zn and Mn availability is restricted by low temperatures, high-pH soils, nutrient antagonisms, low soil reserves or high production levels. Its natural-origin lignosulfonate complex supports nutrient uptake while providing a biodegradable organic carrier.

How it works / Technical advantages
LIGNO Zn-Mn combines 4.5% manganese and 4.5% zinc in a highly soluble formulation complexed with lignosulfonic acid. This natural biodegradable polymer supports assimilation and makes the product suitable for both foliar and soil correction programmes.
Manganese contributes to growth-hormone synthesis, enzyme function and protein synthesis, while zinc supports enzyme activation, chlorophyll synthesis, nitrate reduction and protein synthesis. The combination therefore addresses two micronutrients involved in core crop metabolic processes.
Application rates and timing
Application Guidance: General foliar dose: 300-500 cc/hL per application on all crops. Use the crop-specific foliar programmes below where available. For soil application, use 4-8 L/ha for 2-4 applications at 15-20 day intervals according to crop need.
Soil application
| Crops | Timing | Dose | Notes |
|---|---|---|---|
| All crops | During periods of greatest need, at 15-20 day intervals | 4-8 L/ha | 2-4 applications depending on crop needs. |
Foliar application
| Crops | Timing | Dose | Notes |
|---|---|---|---|
| Fruit trees | Pre-flowering, fruit set, fruit enlargement and after harvest | 300-400 cc/hL | 3-4 applications. |
| Citrus | During spring and summer budding, when new shoots reach approximately two-thirds of their size | 400 cc/hL | |
| Extensive crops | From the beginning of growth; at 2-4 cm for flax and 5-6 leaves for maize | 300 cc/hL | 1-2 applications. |
| Vegetable crops | First application when plants are well rooted and leaves are well developed; repeat every 15 days | 300 cc/hL | |
| Crops susceptible to zinc and manganese deficiencies | On sufficiently developed leaves at 15-20 day intervals | 300 cc/hL | 2-4 applications. |
| Olive trees | First at the beginning of the cycle in spring; second during fruit enlargement from September to October | 300-400 cc/hL | |
| Vine and vineyard | 1) Separated inflorescences; 2) flower buds; 3) fruit set; 4) veraison | 300-400 cc/hL | Up to 4 stage-based applications. |
Additional technical information
Target problem / deficiency symptoms
LIGNO Zn-Mn is designed to prevent and correct simultaneous zinc and manganese deficiencies. Risk increases under low temperatures, high-pH soils, nutrient antagonisms, low soil micronutrient levels and high-yielding conditions that increase Zn and Mn demand.
Mixing & compatibility
When mixing with other products, always carry out a preliminary compatibility test before application.
Precautions & storage
Avoid treatments during extreme drought, excessive humidity, frost or rain, and when these extreme conditions are expected.
