Maintain the integrity of plant cells

Agro-Ca is a calcium-based liquid foliar nutrient, specially formulated to prevent and correct nutritional and physiological imbalances caused by deficient or poor calcium assimilation.

Calcium plays an important physiological role as a component essential to cell walls, that are indispensable to the plant’s normal development. Indeed, it provides a physical barrier against the penetration of pathogens. It is essential in regulating enzymatic systems, phytohormone activities (auxins) and to good nutrient absorption. Calcium also plays a role in pollen fertility. Calcium is a second messenger in many transduction signal pathways in the plant that coordinate some cellular activities. Calcium plays a vital role in the crop’s resistance to stress.

Due to the limited mobility of calcium in the plant, calcium deficiency manifests itself in leaves and younger fruits. It is therefore important to provide a continuous supply of calcium to encourage whole-plant growth. Using Agro-Ca contributes to the production of superior quality crops and greater crop preservation. Regular foliar applications of Agro-Ca provide the required level of calcium considered essential for good calibre development, firmness, resistance to stress and disease, and preservation capacity. Agro-Ca helps to fight against physiological disorders linked to calcium deficiency in fruit and vegetable crops: bitter pit in apple, leaf tip-burn in lettuce and cabbage, blossom-end rot in tomato, pepper, and cucumber, blackheart in celery, cracking in citrus fruits, prune and cherry, coulure in grapes and olives, etc.

  • Reduction of many physiological disorders
  • Better fruit and vegetable quality
  • Better fruit and vegetable preservation
  • Decreases crop injuries caused by machinery
  • Resistance against diseases

In conclusion, Agro-Ca can be applied though the crop’s entire growth cycle to sustain the plant’s development. Calcium is transported by the massive flow of water, thus it is dependent upon transpiration. Agro-Ca is highly recommended in the hotter periods of summer when transpiration decreases and during the phases of fructification and fruit bulking.
