FOSS CAL is a product developed for the prevention and correction of calcium deficiencies, and as an agent that induces the natural defenses of plants.
Calcium is a key element for the life cycle of plants, influencing the processes involved in germination and the maturation of the fruits. Calcium increases the resistance of plant tissues. FOSS CAL provides high mobility calcium, which is why it is especially recommended to control different physiopathies caused by deficiencies of this element, such as apical necrosis, fruit fall in citrus fruit, bitterpit in apples, and black heart in beet, etc.
The phosphorus of FOSS CAL increases the resistance of the plant against cryptogamic diseases. Phosphite ion stimulates growth and acts on the plant’s hormonal system, promoting the production of phytoalexins, low molecular weight antimicrobial compounds, which limit the action of pathogens. FOSS CAL is absorbed quickly and reaches all parts of the plants with minimal energy expenditure.
