Hard Cal” is a unique compound in the world of plant nutrition. It is a liquid compound that contains the elements calcium, boron, and molybdenum at concentrations needed by plants. It works to:

1. Promote the growth of pollen grains on flower stigmas, enhance the fertilization process, and ensure the completion of the fruit-setting process.
2. Reduce flower drop, prevent fruit shedding, increase fruit firmness, and improve fruit quality, thereby enhancing the ability of fruits to withstand shipping and storage.
3. Increase root hairs, leading to the formation of a strong root system, improving nutrient absorption from the soil, and consequently increasing crop yield.
4. Improve the shape, uniformity, and consistency of fruit size, especially in grape crops.
5. The presence of calcium and boron together promotes cell elongation and division, as well as the reinforcement of cell walls, making the plant more resistant to fungal diseases.
6. The unique composition of Hard Cal prevents physiological disorders resulting from a deficiency of calcium and boron, such as bitter pit in apples, blossom-end rot, and fruit cracking.
7. The presence of boron aids in the absorption of calcium, making it more available, as boron is essential in building calcium within the cell.

Hard Cal is free from nitrates, sulfates, carbonates, and chlorides, allowing it to be used for foliar spraying or added to irrigation water without causing any harm to the plant.
