Calcium is an essential nutrient that allows plants to grow, develop, remain healthy and reproduce optimally to form seeds or fruits. Although it’s considered a secondary nutrient, a plant’s need for calcium can be as high as its needs for primary nutrients such as nitrogen and potassium.

Calcium (Ca) is the backbone of every living organism, including plants. Although a plant’s needs for calcium can be as high as its needs for nitrogen and potassium, it is classified as a secondary nutrient. In this post, we examine the importance of calcium and the factors that can limit its availability to plants.

Required by all plants to grow and thrive, calcium (Ca) plays a big part in plant development and fruit quality. Although it’s considered a secondary nutrient, a plant’s need for calcium can be as high as its needs for nitrogen and potassium. 

Calcium is essential for the proper functioning of growing points, particularly root tips and nodules. It aids in cell division, forms compounds which strengthen cell walls, supports the function of cell membranes, and helps control enzyme activity and the metabolism of starch.
