The Science Behind

How Calcium Nitrate (N 15.5% + Ca 18.5%) Works

Understanding how Calcium Nitrate (N 15.5% + Ca 18.5%) supports calcium nutrition, nitrogen availability, cell wall strength, fruit setting, soil structure, crop quality, and post-harvest durability.

Total Nitrogen 15.5% + Total Calcium 18.5%

Calcium Nitrate (N 15.5% + Ca 18.5%) provides crops with a quick and water-soluble source of calcium and nitrogen. Calcium plays an important role in cell wall formation, plant structure, fruit firmness, fruit setting, and shelf life. Nitrogen supports vegetative growth and crop development. Together, they help improve plant strength, nutrient availability, fruit quality, and overall crop performance.

  • Cell Wall Strength Support

    Calcium supports stronger cell walls, improving plant structure, fruit firmness, and crop stability.

  • Quick Nitrogen Availability

    Provides readily available nitrogen that can be quickly absorbed by crops during active growth stages.

  • Fruit Quality Support

    Supports fruit setting, fruit development, post-harvest durability, and overall crop quality.

Detailed Process Breakdown

Each stage of Calcium Nitrate (N 15.5% + Ca 18.5%)’s calcium nutrition, nitrogen availability, cell wall support, soil improvement, and fruit quality support process.

Stage 1

Soil Application

Use 10–20 kg per acre through soil application as per crop type and requirement.

Stage 2

Basal / First Irrigation Use

Calcium Nitrate (N 15.5% + Ca 18.5%) can also be used at 20–50 kg per acre as basal application at sowing or at first irrigation, depending on crop production capacity.

Foliar Spray

Use 5–10 gm Calcium Nitrate (N 15.5% + Ca 18.5%) per liter water for foliar spray from pre-flowering to fruit formation stage.

Stage 4

Cell Wall Formation

Calcium supports cell wall strength, plant structure, fruit firmness, and crop stability.

Stage 5

Soil Structure Support

Helps maintain soil structure and supports displacement of sodium salts, especially under saline irrigation conditions.

Stage 6

Fruit Quality & Shelf Life

Supports fruit setting, fruit development, better crop quality, and post-harvest durability.

Product details

It's an important Calcium source, an essential macronutrient in forming the cell walls within the plant, giving them greater strength and stability, favoring the fruit settings with greater consistency and post-harvest durability. The product is the most indispensable fertilizer for a continuous application along a crop’s growth cycle, be it fertigation or hydroponics. Select Calcium will help maintain an optimum level of Calcium in the plant and will prevent or correct any deficiencies. Being a great water-soluble source of nitrogen and calcium in an easy-to-absorb form, it leads to quick benefits for the crops throughout their growth period. It will help your fruit and vegetables have a longer shelf life and a better quality all round.

Calcium Nitrate (N 15.5% + Ca 18.5%) provides a rich source of calcium and nitrogen nutrients vital for the growth and development of crops. Due to its water-soluble formulation, it quickly dissolves in water which makes it easy to apply through foliar or drip irrigation systems, and is readily absorbed by the crops. It also helps to neutralize the soil ph levels and improves the soil structure and nutrient availability. It is compatible with other fertilizers and agrochemicals which makes it easier to be mixed with other combinations of nutrients to meet specific nutrients of the crop.
