Description

Calcium deficiency symptoms appear initially as localized tissue necrosis leading to stunted plant growth, necrotic leaf margins on young leaves or curling of the leaves, and eventual death of terminal buds and root tips. Generally, the new growth and rapidly growing tissues of the plant are affected first. Calcium is extremely immobile in the plant and therefore effects new tissue, especially meristems first. Calcium deficiency is difficult to manage and is often a problem in tomato and pepper production resulting in browning of the fruit tip. Calcium deficiency can be a problem in acid soils. Sometimes liming of acid soils only results in an increase of the pH in the top horizon (0-30) cm resulting in stunted root growth into deeper layers.

Symptoms:

• Parachute shaped leaves
• Disformation and dying of tips (meristems). Typically death of root tips. Dying of meristems results in many branches
• Chlorosis among the leaf margins
• Dark veins
