Smarter calcium nutrition

Póma is a calcium acetate-based liquid foliar nutrient, specially designed to prevent and correct nutritional and physiological imbalances caused by deficient or poor calcium assimilation. Calcium is chelated with acetic acid which is found naturally in all living organisms, thus it is not toxic and it is involved in many metabolic processes of the plant. Póma is a chlorine- and nitrogen-free solution containing a multifunctional adjuvant (adhesive, penetrating, damping, anti-foaming and tensioactive agents) that allows calcium to remain in solution longer on the leaf without being washed out and helps to penetrate the leaf more easily.

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. Acetic acid takes part in the synthesis of many metabolic substances indispensable to plants, by stimulating  photosynthesis, and improving tolerance to drought.

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 Póma contributes to the production of superior quality crops and greater crop preservation. Regular foliar applications of Póma provide the required level of calcium considered essential for good calibre development, firmness, resistance to stress and disease, and preservation capacity. Póma 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. Since it is nitrogen-free, Póma can be applied late in the orchard without posing a risk to premature ripening, colouration, and fruit preservation. Póma is recommended to apple growers cultivating varieties with chlorine-sensitive foliage such as McIntosh, Golden Delicious or Idared.

  • Calcium complexed with organic acids and its formulation is chlorine- and nitrate-free
  • Tensioactive agent (droplet distribution)
  • Damping agent (evaporation restriction)
  • Adhesive agent (anti-washout)
  • Penetrating agent (passage of mineral elements through the leaf wall)

In conclusion, Póma 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. Póma is highly recommended in the hotter periods of summer when transpiration decreases and during the phases of fructification and fruit bulking.
