A soluble iron chelate with a very high stability constant will be less effective as a fertilizer material than one with a lower stability constant.

Question

Quizplus · Accepted Answer

A higher stability constant means that the iron chelate is less likely to release its iron ions, making it more stable but also less available for plant uptake. Therefore, a chelate with a lower stability constant is more effective as a fertilizer material because it releases its iron ions more readily for plant use.
