Optimization of Plant Health

Growers and universities have focused for centuries on the optimization of plant health by way of controling “limiting factors” of plant nutrition.

Light, temperature, water, and nutrition are all important when it comes to growing healthy plants. Growers and universities have focused on for centuries, the optimization of plant health by way of controling “limiting factors” of plant nutrition.


The Science

J. Von Liebig’s “law of the minimum,” states that “The availability of the most abundant nutrient in the soil is only as good as the availability of the least abundant nutrient in the soil.” Or, to put it more plainly, “A chain is only as strong as its weakest link.”
 
An image of a barrel—often called Liebig’s barrel—explains Liebig’s law. Just as the capacity of a barrel with staves of unequal length is limited by the shortest stave, so a plant’s growth is limited by the nutrient in shortest supply.
