Example of the Law of the Minimum Mean

The law of the minimum mean was made by Justus Liebig in 1840, and indicates that the existence and survival of a biological organism is not determined by large contributions nutritious, but is determined by those that are absorbed in very small amounts, being valid in plants and in animals.

Two examples of the law of the least average:

Example 1.- Boron in the tomato or tomato plant:

In the tomato plant (also known as tomato), for its optimal growth, it requires the chemical element "boron", which is necessary in small quantities,

In case of not having it or if it is below its requirements, the plant would lose resistance to the sun's rays, dehydrating and burning, as well as the fact that its fruits cannot ripen or grow up.

Example 2.- On vitaminization with vitamin A:

A woman, from the age of 11, requires a daily intake of 800 micrograms of vitamin A, while a man requires about 1000 micrograms.

This is the mean minimum. The body of a person produces a part of this vitamin from some foods and when this amount is exceeded for some time, or for some exceptional circumstance (vitamin A overdose) produces visual disturbances, stomach pain, drowsiness, dizziness, nausea, hair loss, pain in the bones.

In the opposite case, when there is deficiency or lack, the person has visual acuity problems, especially night vision, and his immune system weakens, making him more susceptible to disease infectious.

Therefore, in this case, the minimum medium in the carrying of vitamin A, which is obtained through food and the proper use of vitamin supplements, allows for a good state of health.
