Nutrients

Crop scientists recognise that plants need 13 essential mineral nutrients, all of which play a number of important functions. Many of these essential nutrients can be found in the soil, but often in insufficient quantities to sustain high crop yields. If something is lacking, plant growth and yield suffer.

This is in accordance with ‘Liebig's law of the minimum’ – which states that plant growth is controlled not by the total amount of available nutrients, but by the nutrient in shortest supply. Increasing the amount of the limited nutrient will ultimately result in improved plant growth.
