Code registration number: 22694

Calvin is a highly water-soluble powdered fertilizer based on calcium carboxylate, free of any chlorine or nitrate. Due to its chelate structure with carboxylic acids, Calvin significantly increases the absorption and transport of calcium in the plant and prevents calcium from stabilizing in the soil, which is why it is highly effective even in alkaline or highly acidic soils.

This high purity powder product, containing 42% calcium oxide (CaO) equivalent to approximately 30% pure calcium, with carboxylic chelate, is a highly effective and stable source of calcium for plant nutrition and correction of calcium deficiencies. This product, with its high water solubility, can be used for foliar spraying, soil application and drip irrigation. Its special formula ensures rapid absorption, stability in alkaline soils and reduces the risk of locking and sedimentation.

This compound is designed for use in a variety of horticultural, agricultural, greenhouse and ornamental crops and plays a key role in increasing crop quality, preventing fruit drop and improving storage life.

  • Fast and effective supply of calcium required by the plant
  • Increase cell wall strength, reduce flower and fruit drop
  • Prevent calcium deficiency symptoms such as bitter apple spot, tomato inflorescence rot, pistachio bone skin spot, fruit cracking and leaf tip burn
  • High absorption capacity even in high pH and calcareous soils
  • Reduce calcium locking and increase its mobility in plant tissue
  • Increase solution stability and prevent sedimentation
  • Fully water-soluble powder, no sediment and mud
  • Can be used in foliar spraying, drip irrigation and soil application
  • High purity, economical and cost-effective formulation
  • Increase the quality, color, weight and shelf life of the final product

1. Safety tips for the user:

  • When using, wear gloves, a mask, and protective glasses to prevent direct contact with skin and eyes.
  • In case of contact with skin or eyes, rinse immediately with plenty of water.
  • Avoid direct inhalation of product vapors or particles.
  • Keep out of reach of children and animals.
  • After use, wash your hands and face with soap and water.

 

2. Storage conditions:

  • Store in a dry, cool place away from direct sunlight.
  • Protect from frost and temperatures above 35°C.
  • Close the product lid tightly after each use to prevent contamination and evaporation.

 

3. Precautions for the plant and the environment:

  • Do not use more than the recommended amount, as it may cause leaf burn or disrupt plant growth.
  • Spraying should be done during the cool hours of the day (early morning or evening) and in windless conditions.
  • Perform a compatibility test before mixing with other fertilizers and pesticides.
  • Avoid allowing residual solutions to enter water sources, rivers, and drinking water wells.
  • If the product is spilled on the ground, clean it up with absorbent materials such as soil or sand and prevent it from entering the sewage system.

 

For precautions when mixing with other fertilizers and pesticides, the following points should be noted:

  • Before mixing, perform a compatibility test. Mix a small amount of the product with the intended fertilizer or pesticide in a small container and check that no precipitation, discoloration, or abnormal reaction occurs.
  • Do not mix with high calcium fertilizers (such as calcium nitrate) and compounds containing copper and sulfur. These compounds may cause precipitation and reduce effectiveness.
  • Do not mix with strong alkaline compounds (PH above 8) such as some agricultural pesticides and detergents, as this may cause the breakdown of amino acids and reduce product efficiency.
  • Be careful with mineral oils and petroleum-based compounds. In some cases, they may reduce absorption or stain the leaves.
  • Mixing with systemic insecticides and fungicides is usually safe, but caution should be exercised regarding dosage. It is always recommended to test on a few plants before using on a large area.
  • For liquid fertilizers and humic acids, mixing is usually straightforward, but the order of addition is important. Add water first, then amino acid, and finally other fertilizers to prevent settling.
  • After preparing the solution, use it immediately. Prolonged storage of the solution may cause deterioration of quality and precipitation.
