SIL CA
Calcium Silicate Fertilizer for Stronger Plant Tissues, Better Fruit Resistance and Improved Crop Resilience
SIL-CA is a high-value nutritional solution based on calcium silicate, developed to strengthen the structural integrity of plants throughout the crop cycle. Calcium plays an essential role from germination to fruit ripening, helping to improve cell wall strength, tissue firmness and overall plant resistance. Silicon complements this action by accumulating in epidermal tissues, where it contributes to the formation of a physical barrier that helps reduce the impact of abiotic stress, mechanical damage and certain biotic pressures.
By improving the mechanical stability of the plant, SIL-CA supports stronger stems, more upright leaves and better light interception. This structural improvement can enhance photosynthetic efficiency, nutrient uptake and fruit quality, making it especially useful in crops exposed to high temperatures, drought stress, salinity, heavy production loads or handling-related damage.

Multi-Benefits
SIL-CA provides a combined calcium and silicon effect that helps reinforce plant structure, improve fruit firmness and support crops during critical physiological stages. Its benefits are especially relevant in intensive agriculture, where plants are exposed to high productive demand, environmental stress and frequent handling.
The product contributes to stronger epidermal tissues, improved mechanical stability, better resistance to lodging, enhanced tolerance to drought and heat stress, reduced sodium uptake under saline conditions, and improved post-harvest performance. It also supports the uptake of key nutrients such as nitrogen, phosphorus, potassium and micronutrients.
Key Benefits
- Stronger plant tissues: Calcium and silicon help reinforce cell walls and epidermal structures, improving plant firmness and resistance.
- Improved fruit quality: SIL-CA helps increase fruit resistance to friction, manipulation and physical damage, supporting better marketability.
- Support against pathogens and pests: Silicon deposition in epidermal tissues provides a physical barrier that can help crops better tolerate pest and disease pressure.
- Better stress tolerance: The formulation helps reduce the impact of drought, heat, salinity and certain heavy metal toxicities by supporting stronger plant physiology.
- Enhanced photosynthetic performance: Stronger stems and more erect leaves improve light capture and plant efficiency.
- Post-harvest support: By reinforcing tissues, SIL-CA helps improve fruit shelf life and resistance during transport and handling.
Technical Advantages
SIL-CA combines two structural nutrients with complementary functions. Calcium strengthens cell walls and membranes, while silicon accumulates in tissues and contributes to a protective, reinforcing effect. This dual action makes the product suitable for programmes focused on crop fortification, fruit quality, stress management and post-harvest performance.
Its neutral-to-slightly alkaline pH of 7.8 and liquid format allow practical use through foliar sprays or soil applications. The product is suitable for a wide range of crops, including vegetables, fruit trees, berries, ornamentals, banana, papaya, grasses and field crops.

Features and Properties
SIL-CA can be applied by foliar spray or through soil application, depending on crop type, crop stage and production objective. The datasheet gives doses in L/ha/application. Application should be made with adequate water volume to ensure uniform coverage or distribution in the root zone.
For foliar applications, SIL-CA is best used during periods of active growth, before or during stress periods, and during fruit development when firmness and resistance are key. For soil applications, it can be integrated into nutritional programmes aimed at strengthening root activity, improving nutrient balance and supporting crop resilience.
Recommended Crops and Timing of Application
SIL-CA is recommended for crops that require stronger tissues, improved fruit firmness, better stress tolerance and enhanced resistance to physical damage. It is particularly suitable for garlic, onion, banana, berries, crucifers, cucurbits, fruit trees, cereals and other gramineae, lettuce, legumes, ornamentals, papaya, grass, solanaceous crops and carrot.
The best timing is during active vegetative growth, before periods of abiotic stress, at flowering and fruit set, during fruit enlargement and in the weeks before harvest when fruit firmness, resistance and shelf life are key commercial objectives. In crops sensitive to cracking, bruising, handling damage or lodging, SIL-CA should be included preventively within the crop nutrition programme.
