For most plants the relationship between plant tissue concentration of a nutrient and the dry matter production of the plant is linear until toxicity begins to have an effect.

Question

Quizplus · Accepted Answer

The relationship between plant tissue concentration of a nutrient and the dry matter production of the plant typically follows a curve, not a linear pattern. Initially, as nutrient concentration increases, dry matter production increases up to an optimum level. Beyond this optimum, further increases in nutrient concentration can lead to toxicity, reducing dry matter production. This relationship is often depicted as a sigmoid curve, illustrating initial deficiency, optimal range, and toxicity.
