Calcium is a fundamental component of cell walls, helping to build a strong structure and ensuring cell stability. Calcium-enriched cell walls are more resistant to bacterial or fungal attack.
Calcium also helps the plant adapt to stress by influencing the signal chain reaction when stress occurs. It also plays a key role in regulating the active transport of potassium to stomatal opening.
Deficiency – The plants have yellow leaves curled around the upper leaves, burns at the tip and small chlorotic leaves. Deficiency interferes with root growth, causes deformation of foliage growth tips, which can result in reduced yields and poor quality. Calcium-deficient potato tubers have reduced storage capacity.
