FERTILIZERS ON THE BASE OF CALCIUM
Calcium is an essential nutrient and has an important role in several physiological processes, such as: cell growth and development, building and strengthening of the cell wall, metabolic processes and activation of feed absorption as well as hormonal control of enzyme activity. Calcium regulates the function of stomata and alleviates temperature stress. It also induces plant resistance to pathogens. The quantity of absorbed calcium in vegetables and fruit influences not only the yield, but also the quality, longevity and transportability of fruits. Certain plant species are very sensitive to calcium deficiency, manifested mainly on fruits, which drastically reduces their quality and price. Therefore, a timely treatment of crops is often necessary with one of the selected fertilizer formulations based on calcium.
