Fe-EDTA
B.
Fe-EDDHA
C.
Fe-DTPA
D.
Fe-HEDTA
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
Fe-HEDTA is the Iron chelate suitable for application to crops grown on acid soils.Fe-HEDTA is Fe-Hydroxyethylenediaminetriacetic (Hydroxy ethylene diamine triacetic) acid. Iron is an essential nutrient for the growth of the plant, it acts as a component of many enzymes and catalyzes the formation of precursors of chlorophyll.
The stability of iron chelates also depends on the hardness of the water and the pH of the soil.
