Thakar Caltop Concentrated Liquid Calcium 11% Fertilizer for Foliar Spray & Drip Fertigation

Thakar Caltop is a concentrated liquid calcium fertilizer containing 11% Calcium (as Ca), specially formulated for foliar spray and drip fertigation in fruit and vegetable crops. Calcium is one of the most important nutrients for plant health. It strengthens cell walls, supports early root development, and improves the uptake of other essential nutrients like nitrogen, iron, zinc, copper, and manganese. This makes Caltop a practical and flexible choice for farmers who want to correct calcium deficiency and improve overall crop quality.

Caltop is highly soluble and quickly absorbed by plant tissues, making it effective for managing calcium-related disorders such as blossom end rot in tomato and chilli, tip burn in leafy vegetables, fruit cracking, and bitter pit. By supplying calcium in a readily available form, it enhances flowering, fruiting, and the plant's natural resistance to pests and diseases. Manufactured by Thakar Chemicals, this liquid fertilizer is compatible with almost any tank mix, giving farmers greater flexibility in their field recommendations.

Whether you are growing fruits like banana, pomegranate, apple, grapes, guava, and citrus, or vegetables like tomato, chilli, brinjal, okra, cauliflower, and cucurbits, Caltop helps deliver stronger plants and better yields. It can be applied through foliar spray at 1 ml per litre of water or through drip fertigation at 500 ml per acre, making it easy to fit into your existing crop nutrition program.

Key Benefits

• Supplies readily available liquid calcium for fast absorption by plant tissues.
• Reduces calcium-related disorders like blossom end rot, tip burn, fruit cracking, and bitter pit.
• Strengthens plant tissues and cell walls for healthier, sturdier plants.
• Promotes early root development and overall plant growth.
• Improves uptake of essential nutrients like nitrogen, iron, zinc, copper, and manganese.
• Enhances flowering, fruit set, and overall fruit quality.
• Increases natural resistance of plants against pests and diseases.
• Compatible with a wide range of tank mixes for greater flexibility in field use.

How It Works

Caltop supplies calcium in a concentrated liquid form that is readily available to plants. When applied through foliar spray, the calcium is quickly absorbed through the leaf surface and moves into the plant tissues. When applied through drip fertigation, the calcium is taken up by the roots along with irrigation water.

Once inside the plant, calcium plays a key role in building strong cell walls and membranes. This strengthens plant tissues, making them firmer and more resistant to physical damage and disease attack. Calcium also supports early root development, which helps the plant take up water and nutrients more efficiently.

By improving the overall nutrient balance, Caltop enhances the uptake of other essential nutrients like nitrogen, iron, zinc, copper, and manganese. This leads to better flowering, improved fruit set, and higher quality produce. The strengthened plant structure also improves natural resistance to pests and diseases, helping the crop stay healthy through the growing season.

When to Use

Caltop is most effective when applied at the right crop stages and conditions. For best results, follow these practical guidelines:

• Apply during active growth stages when the plant needs calcium the most, such as flowering and fruit development.
• For foliar spray, apply during morning or evening hours when temperatures are cooler and leaves can absorb the solution better.
• Avoid application during heavy rains or high temperatures, as this reduces absorption and effectiveness.
• For drip fertigation, ensure uniform distribution through the irrigation system for even calcium uptake.
• Use Caltop when you notice early signs of calcium deficiency, such as blossom end rot, tip burn, or fruit cracking.

Step by Step Usage Instructions

1. Wear gloves, a mask, and protective clothing before handling the product.
2. For foliar application, mix 1 ml of Caltop per litre of clean water in the spray tank.
3. Stir the solution well to ensure uniform mixing.
4. Spray evenly on the leaves, covering both upper and lower surfaces for better absorption.
5. Apply during morning or evening hours to avoid heat stress and improve uptake.
6. For drip fertigation, apply 500 ml of Caltop per acre through the irrigation system.
7. Ensure uniform distribution so all plants receive an equal amount of calcium.
8. After application, clean the spray equipment and store the remaining product properly.

Compatibility

Caltop is suitable for almost any tank mix, which gives farmers greater flexibility in combining it with other fertilizers and crop protection products. However, it is always advisable to do a small jar test before mixing with new products to confirm compatibility. Avoid mixing with strongly alkaline solutions unless tested, as this may reduce effectiveness.

Precautions & Safety

• Wear gloves, a mask, and protective clothing while handling and applying the product.
