Liebig’s Law applies to plant growth and can be summed up as this:
“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.”
For example, the growth of an organism such as a plant may be dependent on a number of factors, such as sunlight or mineral nutrients (e.g. nitrate orphosphate). The availability of these may vary, such that at any given time one is more limiting than the others. Liebig’s Law states that growth only occurs at the rate permitted by the most limiting. – Wikipedia .........Gosh, global night brightening seems to be growing faster than global warming.
