I first want to thank Tapla for showing me Liebig's law of the minimum. I have learned countless information from Tapla. He inspired me to make an example of why plant hormones are not needed and do little to nothing when included in a fertilizer program using Liebig's law of the minimum.

My example of Liebig's law of the minimum.

"If a fertilizer program was missing CK's, GA's and Auxin and had all basic macro and micronutrients (including calcium I used for an example) yield and the nutrition of the crop would be high.

Now if a fertilizer program had CK's, GA's and Auxin and all macro and micronutrient EXCEPT Calcium, then you would have a lot of problems.

Key Point-What I am saying is CK's, GA's and Auxin are not needed like calcium is thus are not as effective at increasing yield.

This is an example of Liebig's law of the minimum"
