Silicon-based solutions for crop nutrition and plant resilience
Silicon fertilizer for plants is used in crop nutrition programs to supply silicon in forms designed for agricultural application. Depending on the formulation, silicon can be combined with calcium, magnesium, potassium, iron, zinc, amino acids or seaweed-derived components.
Tangel Agro’s silicon range includes foliar and soil-applied solutions for professional agriculture. The portfolio is designed to support plant tissue strength, nutrient management and tolerance to adverse growing conditions across a wide range of crops.

Silicon is used in agricultural nutrition to support plant structure and crop performance. According to Tangel Agro’s silicon product range, silicon can accumulate in plant tissues, contribute to stronger cell walls and support plant tolerance to environmental stresses such as heat, drought and salinity.
The range combines silicon with complementary nutrients and ingredients such as calcium, magnesium, potassium, iron, zinc, amino acids and seaweed extract, allowing growers to select a formulation according to the nutritional objective of the crop.
Silicon-based fertilizers are used in professional agriculture where stronger plant tissues and improved tolerance to adverse growing conditions are desired. In Tangel Agro’s product datasheets, silicon is associated with reinforcement of epidermal tissues, support for plant structure and improved tolerance to drought and heat stress.
Different formulations make it possible to combine silicon nutrition with calcium, magnesium, potassium or micronutrients depending on crop requirements.
Tangel Agro’s silicon portfolio covers several nutritional approaches. SIL-CA and SIL-CA Mg combine silicon with calcium, with SIL-CA Mg also supplying magnesium. SIL Fe Zn combines silicon with iron and zinc, while SIL-AA combines silicon and potassium with free amino acids.
SIL-MARE NPK adds an NPK profile and natural seaweed extract, providing a broader nutrition option within the same silicon category.
The silicon range includes products for foliar use, soil application, or both, depending on the formulation. SIL-AA is designed for foliar use, while SIL-CA and SIL-CA Mg can be used through foliar and soil applications. SIL Fe Zn also supports foliar and soil programs.
Application rates and timing vary by crop and product. Always follow the relevant Tangel Agro datasheet when integrating a silicon fertilizer into an agricultural nutrition program.

Silicon fertilizers are used in crop nutrition to supply silicon and support plant structure. Tangel Agro’s datasheets also associate silicon with stronger tissues and improved tolerance to adverse environmental conditions.
In search terminology, “silica for plants” is often used broadly when referring to silicon-based plant nutrition. Agricultural products, however, can supply silicon in different silicate or silicon-containing formulations, so the product composition should always be checked.
It depends on the formulation. Within the Tangel Agro range, SIL-CA and SIL-CA Mg support foliar and soil application, while SIL-AA is formulated for foliar use.
The range includes formulations combining silicon with calcium, magnesium, potassium, iron, zinc, free amino acids, NPK nutrients and seaweed extract.
Tangel Agro’s silicon datasheets cover horticultural crops, cereals, fruit crops, vines, berries, potatoes and other crop groups. Application rate and timing depend on the specific product and crop.
