What is a chelate? The word chelate (pronounced: “key-late”) is derived from the Greek word “chele” which literally means “claw”. Hence, chelate refers to the pincer-like manner in which a metal nutrient ion is encircled by the larger organic molecule (the claw), usually called a ligand or chelator. Chelated micronutrients are protected from oxidaon, precipitaon, and immobilizaon in certain condions because the organic molecule (the ligand) can combine and form a ring encircling the micronutrient. The pincer-like manner in which the micronutrient is bonded to the ligand changes the micronutrient’s surface property and favors the uptake efficiency of foliarly applied micronutrients. Chelaon occurs when certain large molecules form mulple bonds with a micronutrient, protecng it from reacng with other elements in the nutrient soluon and increasing its availability to the plant. Why are Krystal Klear ® micronutrient soluons so effecve? Dual Chelaon: Ulizes patented, biodegradable IDS in conjuncon with EDTA to maximize the benefits of both chelang agents. Stability Constant, which refers to the equilibrium state of a metal caon and a ligand to form a chelang complex: A good stability constant is one in which the bond is strong enough to hold the metal in soluon but not so strong that it doesn’t release the metal when applied. Number of ligands: This refers to the ligands or “legs” that bond the metal to the chelang agents. For example, EDTA has 6 and LidoQuest® IDS-40 has 5 ligands while citric acid has 3 carboxylic ligands and glucoheptonate has 1. The higher the number of legs means more caon surface area is covered. That is why both EDTA and LidoQuest® IDS-40 chelated metals are stable in orthophosphate soluons for an extended period while others fall apart and precipitate over me. Chelated metal being protected from aracon to other materials. A good chelang agent protects the metal from all sides. 20-20-20 with Krystal Klear Fe 20-20-20 20-20-20 with Fe citrate R

Chelated Micronutrient SolutionsThe Performance Edge: Patented Dual Chelation
What is a chelate?The word chelate (pronounced: “key-late”) is derived from the Greek word “chele” which literally means “claw”. Hence, chelate refers to the pincer-like manner in which a metal nutrient ion is encircled by the larger organic molecule (the claw), usually called a ligand or chelator.
Chelated micronutrients are protected from oxidation, precipitation, and immobilization in certain conditions because the organic molecule (the ligand) can combine and form a ring encircling the micronutrient. The pincer-like manner in which the micronutrient is bonded to the ligand changes the micronutrient’s surface property and favors the uptake efficiency of foliarly applied micronutrients.
Chelation occurs when certain large molecules form multiple bonds with a micronutrient, protecting it from reacting with other elements in the nutrient solution and increasing its availability to the plant.
Why are Krystal Klear® micronutrient solutions so effective? Dual Chelation: Utilizes patented, biodegradable IDS in conjunction with EDTA to maximize the benefits of both chelating agents.Stability Constant, which refers to the equilibrium state of a metal cation and a ligand to form a chelating complex: A good stability constant is one in which the bond is strong enough to hold the metal in solution but not so strong that it doesn’t release the metal when applied.
Number of ligands: This refers to the ligands or “legs” that bond the metal to the chelating agents. For example, EDTA has 6 and LidoQuest® IDS-40 has 5 ligands while citric acid has 3 carboxylic ligands and glucoheptonate has 1. The higher the number of legs means more cation surface area is covered.
That is why both EDTA and LidoQuest® IDS-40 chelated metals are stable in orthophosphate solutions for an extended period while others fall apart and precipitate over time.
Chelated metal being protected from attraction to other materials.
A good chelating agent protects the metal from all sides.
