Normally, iron deficiency or any other mineral deficiency is linked to humans. But how many of us are aware of the fact that plants also need their share of iron for healthy growth? Fertilizers contain organic elements that are added to the soil to improve their quality. Iron chelate fertilizers treat iron deficiency in plants and also keep diseases at bay.

Iron Chelate Fertilizer

Chelated iron, also known as iron chelate, is a mixture of iron, amino acids and other substances that is used for the purpose of gardening and agriculture. The iron undergoes a process known as chelation, where its molecules get connected to a single molecule of amino acid. A ring structure of these compounds is formed which aids in its easy absorption into the plant's body. This fertilizer is used in places where the soil has been depleted of its iron content. Owing to this dearth, plants turn yellow due to deficiency and wither away. This plant disease is called chlorosis. In order to prevent it, the soil is mixed with iron chelate. It increases the level of chlorophyll and also reduces the yellowing of stems. It is also one of the best natural lawn fertilizers.


Application of iron chelate to the soil is beneficial for the plants and can be done in a few simple steps.
  • Before using the fertilizer, you must check the soil for its nutrient content and if there is any depletion. The soil sample can be taken to a landscape center to test its condition and fertility.
  • If it shows a deficiency of iron, then the gardening professional may recommend you to use an iron rich fertilizer and also advise you about the composition which is suitable for your soil type.
  • You can purchase chelated iron from various garden centers. It is available in two forms - granulated and liquid. To apply this fertilizer to the soil, follow the instructions that have been given on the package or carton.
  • If you are using the granulated form, then spread the fertilizer on the tilled soil, near the lower stem of the plant. If you are using it on a lawn, then disperse it evenly on the entire lawn, with the help of lawn fertilizer spreaders.
  • For the liquid solution, dilute 6 ounces of iron chelate in 5 gallons of water (approximate amount) and spray it on the lawn and plants. Since iron chelate fertilizer may contain toxins unsafe for humans, it is advisable to wear protective gear like hand gloves and face mask to avoid direct contact.
Always use organic fertilizers to prevent the loss of the soil's natural fertility. Chemical fertilizers can increase the pH levels and the acidity of the soil, which can damage the plants.
