SIL FE ZN
Highly Available Silicon with Iron and Zinc for Stronger, More Resilient Crops
SIL Fe Zn is a high-performance silicon fertilizer developed to help crops maintain active growth under challenging field conditions. Its easily absorbed silicon reinforces cell walls, improving plant structure and helping crops better withstand periods of drought, environmental stress and pressure caused by pathogens or pest attacks.
The combination of silicon, iron and zinc makes SIL Fe Zn especially valuable in crop programs focused on plant resilience, vegetative balance and stress prevention. Silicon contributes to stronger tissues and natural resistance, while iron and zinc support key physiological processes related to photosynthesis, enzymatic activity, chlorophyll formation and balanced growth.
Used preventively, SIL Fe Zn prepares the plant before stress periods. Applied during stress situations, it helps limit their impact and supports recovery. This makes it a strategic product in modern nutrition programs for cereals, horticultural crops, fruit trees and other crops exposed to changing climatic conditions.

Multi-Benefits
SIL Fe Zn offers a combined nutritional and biostimulant effect, making it suitable for inclusion in crop programs aimed at improving resistance, vigour and productivity.
It helps crops tolerate adverse growing conditions such as drought and other abiotic stresses, while also reducing the negative impact of biotic stress caused by pathogens or pest pressure. Its action strengthens plant tissues, supports young root development and contributes to improved yield, quality and storage parameters.
Because of its low recommended foliar dose of 0.5 L/ha, it provides a cost-effective solution for large-scale crop programs, especially in extensive crops.
Key Benefits
- Activates natural plant immune systems.
- Strengthens cell walls thanks to highly available silicon.
- Improves tolerance to drought and abiotic stress.
- Helps limit the impact of pathogen and pest-related stress.
- Stimulates root growth in young plants.
- Supports crop yield, quality and storage performance.
- Suitable for both foliar and soil application.
- Designed for extensive crops with a low treatment cost.
- Excellent miscibility for integration into crop programs.
Technical Advantages
SIL Fe Zn is formulated with a balanced concentration of silicon, iron and zinc to provide both structural and physiological support.
- Silicon strengthens plant tissues and enhances tolerance against environmental stress.
- Iron supports chlorophyll formation, photosynthetic activity and plant metabolism.
- Zinc participates in enzymatic processes, growth regulation and balanced vegetative development.
Its liquid formulation allows easy handling, fast preparation of spray solutions and flexible application through foliar spraying or irrigation systems. The product is especially useful at critical crop development stages, before expected stress periods and during phases of active vegetative growth.

Features and Properties
SIL Fe Zn is a liquid fertilizer and biostimulant for both foliar and soil application, formulated to reinforce crop resilience and support balanced plant development. Its composition combines 18.0% w/v silicon dioxide (SiO₂), 2.0% w/v iron (Fe) and 2.0% w/v zinc (Zn), providing a complete technical profile focused on tissue strengthening, physiological activation and improved plant response under stress conditions.
As an immunity activator and crop biostimulant, SIL Fe Zn is especially positioned for extensive crops, where efficiency, miscibility and low treatment cost are key factors. Its main action is based on improving stress tolerance, strengthening plant structures and supporting natural plant defence mechanisms. The product offers optimal miscibility and is available in 0.5 L, 1 L, 5 L, 10 L, 20 L and 1000 L IBC formats.
Recommended Crops and Timing of Application
Cereals
Use SIL Fe Zn in cereals to reinforce plant resistance during vegetative development, tillering, stem elongation and periods of drought risk. Its low dose makes it especially suitable for extensive crop programs.
Fruit Trees
Apply during active vegetative growth, after stress periods or when the crop requires additional support for tissue strength, quality and productivity. SIL Fe Zn can be integrated into programs aimed at improving plant balance and fruit performance.
Horticultural Crops
Recommended during early vegetative growth, after transplanting, before expected stress periods and during phases of high physiological demand. It supports root growth in young plants and helps crops maintain vigour under pressure.
Stress-Prone Crops
SIL Fe Zn is especially useful when crops are exposed to drought, heat, salinity, pest pressure, pathogen pressure or other conditions that may reduce plant performance.
