Red meat and pomelo need proper amount of calcium fertilizer
Calcium (Ca) has a certain effect on the growth of red meat pomelo fruit. It is a component of the pectin substance in the cell, which maintains the stability of the membrane structure. Calcium is required for the continued growth of meristems and is closely related to root growth. The appropriate amount of calcium can regulate the pH of the soil, promote soil microbial activity and decomposition of organic matter to release various elements. The calcium mobility in the tree is poor, and the calcium content in old leaves and other parts is high. Calcium deficiency is blocked cell division, causing rot roots, shoots, large yellow leaf surface, small fruit deformities, juice, little acid. Excess calcium will make the red meat pomelo fruit smaller, poor coloration and delayed ripening. Excessive calcium application will reduce the effectiveness of phosphorus, manganese, iron, zinc, copper, and boron.
