Medical definitions for chelate To combine a metal ion with a chemical compound to form a ring. To remove a heavy metal, such as lead or mercury, from the bloodstream by means of a chelate.
What is Chelated Iron?
Symptoms of iron deficiency in plants can include chlorotic foliage, stunted or malformed new growth and leaf, bud or fruit drop. Usually, symptoms do not progress more than just discoloration of the foliage. Iron deficient leaves will be green veined with a mottled yellow color in the plant tissues between the veins. Foliage may also develop brown leaf margins. If you have foliage that looks like this, you should give the plant some iron.
What is iron chelator?
They are small molecules that bind to metal ions to make micronutrients, such as iron, more readily available to plants . The word “chelate” comes from the Latin word “chele,” which means lobster claw.
Why is iron useless to plants?
Iron is a metal ion that can react to oxygen and hydroxide. When this happens, the iron is useless to plants, as they are not able to absorb it in this form. To make iron readily available for plants, a chelator is used to protect the iron from oxidation, prevent it from leaching out of the soil and keep the iron in a form that the plants can use.
What does it mean when your plant leaves turn yellow?
Usually, symptoms do not progress more than just discoloration of the foliage. Iron deficient leaves will be green veined with a mottled yellow color in the plant tissues between the veins. Foliage may also develop brown leaf margins. If you have foliage that looks like this, you should give the plant some iron.
Why is iron locked up in plants?
Some plants can be more prone to iron deficiencies. Certain soil types, such as clay, chalky, overly irrigated soil or soils with high pH, can cause available iron to become locked up or unavailable to plants. Iron is a metal ion that can react to oxygen and hydroxide.
What nutrients are needed for fertilizer?
When reading the labels on fertilizer packages, you may have come across the term “chelated iron” and wondered what it is. As gardeners, we know that plants require nitrogen, phosphorus, potassium and micronutrients, such as iron and magnesium, to grow properly and produce healthy blooms or fruit.
Can you use iron without a chelator?
Applying iron without a chelator can be a waste of time and money because the plants may not be able to take up enough iron before it becomes oxidized or leached from the soil. Fe-DTPA, Fe-EDDHA, Fe-EDTA, Fe-EDDHMA and Fe-HEDTA are all common types of chelated iron that you may find listed on fertilizer labels.
What is chelated iron?
Chelated iron is typically iron treated with artificial chelators, an element that ensures that iron remains in an absorbent form so that plants can absorb it. Chelated iron is available in various forms to increase iron deficiency in plants, including water-soluble forms for the formation of leaf sprays or granules that need to be applied to the soil.
How to get iron to adhere to soil?
You can also encourage iron to adhere to natural chelates in the soil by adding organic bark and compost. Chelated iron can save plants on the brink of death by providing them with iron that they can use, but this is not a long-term solution to the problem of iron deficiency, therefore, chelation requires efforts to increase the pH of the soil, increases its acidity and therefore allows plants to receive their amount.

The extensive matrix of chelates found in pH Perfect — including zwitterionic chelates — means your crop will be able to absorb all the necessary micronutrients, regardless of slight variations or changes in your solution’s pH level.
What are the nutrients that plants need?
The Chelation Process. Most growers know about the three major nutrients that plants need: potassium, phosphorus and nitrogen. But many novice growers don’t realize that plants also need other nutrients, like iron, zinc and magnesium. Because they are needed in relatively high quantities, potassium, phosphorus and nitrogen are referred ...
What happens when a chelate bonds to a micronutrient?
When a chelate bonds to a micronutrient, it surrounds or encapsulates individual ions and gives them a negative or neutral charge, allowing the nutrient to enter through the negatively charged pore and travel into the plant’s tissues.
What are the elements that plants need to grow?
Your plants need lower quantities of elements like iron, sulfur and calcium, so we refer to them as micronutrients. While they’re not needed in the same quantities as macronutrients, micronutrients are every bit as vital to your crop’s diet and healthy growth.
Where does the word "chelate" come from?
The word “chelate” — pronounced “KEY-late” — is derived from the Greek word for “claw.” Understanding this, the word’s definition becomes a little clearer: The chelate bonds itself to a metal atom in a clawlike fashion.
How to tell if a plant has iron chlorosis?
If you have looked for these other problems and still suspect iron chlorosis, have your soil tested to see if the pH is above 7.0 to 7.5. If pH is high and you have ruled out other problems then iron deficiency is likely. Leaves with iron chlorosis will develop a yellow color with a network of dark green veins. In severe chlorosis even the veins may turn yellow or the leaf may even turn white. The outer edges also may scorch and turn brown as the cells die. Chlorosis can show an a few leaves, an individual branch, half of the crown, or the entire tree. Not all plants in a landscape will be affected.
How to treat iron deficiency in trees?
These are: 1) soil application of elemental sulfur combined with ferrous (iron) sulfate; 2) soil application of iron chelates; 3) foliar sprays containing ferrous sulfate or chelated iron; or 4) trunk injection of ferric ammonium citrate or iron sulfate (trees only). Foliar treatments produce a rapid but incomplete response, while a soil or trunk treatment will last longer. Soil treatments require considerable work, but generally do not injure trees and can be more economical. Table 2 lists some advantages and disadvantages of different iron chlorosis control methods. Often, one method will work well in one area but not in another due to variations in soil conditions and species susceptibility. Try different methods until you find the one that works in your situation.
How to treat a plant with sulfur?
Instead, treat small areas by making holes 1 to 2 inches in diameter and 12 to 18 inches deep. Space the holes 18 to 24 inches apart around the area within the drip line (outer edge of crown) of affected trees and shrubs. Fill each hole with the iron sulfate-elemental sulfur mixture to within 4 inches of the soil surface. Table 3 provides recommendations for the number of holes and quantity of the ferrous sulfate-elemental sulfur mixture required to treat plants according to their size. Make holes with an auger or soil probe that removes soil to reduce compaction. Avoid damaging large, woody roots when making holes. Also, check with local utility companies if making holes in the vicinity of underground utility lines.
Why are my leaves yellowing?
As noted above, go to What is Iron Chlorosis and What Causes It? for more information on what iron chlorosis is and its causes. Briefly, iron chlorosis is a yellowing of plant leaves caused by iron deficiency, usually in high pH soils (pH above 7.0). Other causes of yellowing need to be ruled out first, however. For example, leaf yellowing can be due to insect or disease problems (pathogenic diseases caused by fungi or other organisms), herbicide misuse, or a history of over watering. Some tree cultivars have even been developed to have yellow foliage on purpose -- an example is the 'Sunburst' honeylocust ( Gleditsia triacanthos var. inermis 'Sunburst') .
