Product Type
Calcium silicate fertilizer
SIL CA
Calcium silicate fertilizer for stronger plant tissues, crop resilience, nutrient uptake, reduced lodging risk and improved post-harvest performance.
SIL CA is a calcium silicate fertilizer for foliar and soil application. It is designed to fortify plant tissues and support crop resistance to physical damage throughout the crop cycle.
The formulation supplies silicon and calcium. The source links silicon deposition in epidermal tissues with stronger plant structure, improved light capture, nutrient uptake, tolerance to environmental stress and post-harvest performance, while calcium is described as important from germination through fruit ripening and for stronger vegetal tissues.

Key benefits and agronomic effects
- Fortifies plant tissues and supports resistance to physical damage.
- Supports a physical barrier in epidermal tissues against pathogens and insects, as described in the source.
- Improves mechanical stability and helps reduce lodging incidence.
- Supports photosynthetic activity through stronger stems and more erect leaves.
- Supports uptake of nitrogen, phosphorus, potassium and micronutrients.
- Supports tolerance to drought, heat and salinity stress.
- Supports post-harvest life and crop quality.
How it works / Technical advantages
SIL CA combines silicon and calcium in a calcium silicate fertilizer for both foliar and soil use. The source states that silicon deposition in epidermal tissues increases mechanical stability and provides a physical barrier to pathogens and insects.
The document also links silicon nutrition with improved uptake of nitrogen, phosphorus, potassium and micronutrients; lower transpiration under drought and heat; reduced sodium uptake under salinity; and regulation of plant uptake under heavy-metal stress. Silicon is also described as associating with cell-wall proteins in post-harvest tissues.

Additional technical information
Target problem / deficiency symptoms
SIL CA is intended for silicon and calcium nutrition where stronger plant tissues and improved structural resilience are required. The source also positions it for lodging reduction, environmental-stress support, nutrient uptake and post-harvest performance.
Frequently asked questions
What is SIL CA?
SIL CA is a calcium silicate fertilizer for foliar and soil application.
What is the composition of SIL CA?
The source lists 24% silicon, printed as SiO₃, and 15% calcium on a % w/v basis. It also gives a density of 1.40 and pH of 7.8.
What is SIL CA used for?
It is used to fortify plant tissues and support structural resistance, nutrient uptake, environmental-stress tolerance and post-harvest performance.
How does silicon support plant structure?
The source states that silicon accumulates in epidermal tissues, increasing mechanical stability and helping reduce lodging incidence.
Can SIL CA support resistance to drought and heat?
Yes. The document states that silicon deposition can reduce transpiration rates and support crops under drought and heat stress.
Can SIL CA support crops under salinity?
Yes. The source states that silicon can help reduce salt stress by inhibiting sodium uptake.
Does SIL CA support nutrient uptake?
The source specifically mentions nitrogen, phosphorus, potassium and micronutrients.
Can SIL CA be applied to the soil?
Yes. The datasheet provides soil rates for garlic and onion, berries, crucifers, cucurbitaceae, gramineae, ornamentals, papaya, grass, solanaceous crops and carrot.
Can SIL CA be applied foliarly?
Yes. Foliar rates are provided for garlic and onion, banana, berries, crucifers, cucurbitaceae, fruit trees, gramineae, lettuce, legumes, ornamentals, solanaceous crops and carrot.
What is the foliar dose for fruit trees?
The documented fruit-tree foliar dose is 2-4 L/ha per application.
What is the soil dose for grass?
The documented grass soil dose is 10-40 L/ha per application.
What pack sizes are available?
SIL CA is available in 1 L, 5 L, 10 L, 20 L and 1000 L formats.
