Iron is essential for plants to produce chlorophyll and use nitrates. Major symptoms of iron deficiency include yellowing of leaves, stunted growth, fomation of small size fruit and flowers. Severe deficiency will result in dying of new shoots and even the death of the plant itself.
Iron chelate has protection against interference of other nutrients in soil. It is highly soluble and is a quick uptake from roots to leaves, leaving little salts in the soil and is a very effective and safe micronutrient.
