Chelates are highly stable products able to maintain the metallic ions surrounded by an organic molecule (chelating agent) so that they are safeguarded from the environment that would favour their precipitation as insoluble hydroxide, unavailable for the plant.

Chelates are often used in agriculture for micronutrient provision. The most commonly used chelates in agriculture are EDTA, DTPA and EDDHA.

Thanks to the organic molecule, the metallic ion is fully available for the plant but free for being retained in media with elevated pH o in competition with other ions.

Chelate efficacy will depend on their reactivity in the medium where they are applied and on the ability of the plant to take the element provided. Foliar chelate applications have generally little effect, and no clear relationship has been described between the chemical composition of the chelate and its effectiveness. When the application is at soil level, the chelate will undergo dissociation and competition reactions due to other ions, or it may be retained on the exchange surfaces. The dissolved chelate should provide the plant with the element it provides.

The efficacy of chelates is not sufficiently evidenced, although it should be noted that the appropriate products should always be used for each agronomic condition and element, at the correct dosage and with products that represent a verified commercial quality.
