Product Introduction

Strengthen your crops from the inside out with highly active Calcium.

Khicha Phoschem Ltd. introduces Astro Calcium as a vital component of our progressive farming plant nutrition range. Calcium is often an overlooked secondary macronutrient, yet it is absolutely essential for the physical structure of the plant. Without adequate calcium, new tissues, root tips, and young leaves fail to develop properly, leading to devastating physiological disorders like blossom-end rot in tomatoes or bitter pit in apples. Astro Calcium delivers this essential nutrient in a highly efficient form, immediately getting to work to bind cell walls together, improve the uptake of other vital nutrients like potassium and magnesium, and ensure a resilient, high-quality, and highly marketable yield.

Key Benefits

Regular application of Astro Calcium protects your crop’s structural integrity and maximizes your marketable harvest.

Dramatically reduces premature flower and fruit dropping.

Increases the post-harvest shelf life and storage capabilities of produce.

Aids in the efficient uptake of other key nutrients like potassium and magnesium.

Method and Quantity of Use

Astro Calcium can be easily integrated into your regular fertilization routine during crucial growth and fruit-setting stages. To maximize structural growth and prevent calcium deficiency disorders, apply Astro Calcium using these effective methods:

01
Foliar Spraying

Mix the recommended dose (typically 2 to 4 grams/ml per liter of water) and spray widely over the leaves, buds, and under-sides of the foliage. For best results, spray during the cooler hours of the morning (before 10 AM) or late afternoon (after 4 PM) to avoid leaf burn.

02
Drip Irrigation

Dissolve the required quantity into your fertigation tank. Apply directly to the active root zone during key developmental stages, especially right before flowering and during active fruit expansion.

Soil Application

Mix the recommended granular/powder dose with a small amount of dry soil or organic compost. Broadcast evenly near the root zone of standing crops or during final soil preparation before transplanting.

Astro Calcium FAQs

How do I know if my crops are suffering from a calcium deficiency?
Because calcium doesn't move easily within the plant, symptoms appear first on the youngest leaves and fruits. Look for stunted or curled new leaves, dead root tips, blossom-end rot on fruiting vegetables, and premature flower dropping.
Can I mix Astro Calcium with other fertilizers or pesticides?
Calcium products can sometimes react with sulfate or phosphate-based fertilizers (creating an insoluble sludge). We highly recommend consulting an expert and conducting a small "jar test" before combining it with any other products.
When is the most critical time to apply calcium?
The highest demand for calcium is during periods of rapid cell division—specifically during early root establishment, right before flowering, and during the initial stages of fruit formation and sizing.
Will this help my harvested fruits last longer during transport?
Yes! Calcium acts like the "glue" holding plant cells together. A crop with adequate calcium levels will produce firmer fruits with significantly better shelf life and storage capabilities.
