As most students of plants know, not all plants of the same species grow at the same rate, and (fertilization) nutrient management can be a cause variability in the growth rate. The real question is: how can plant nutrient management increase or decrease plant growth?

Apical methods are being used in a growing number of field trials and research projects on crop quality, disease impacts, insect attraction, crop yields, and more.

Below are some simple experiments that anyone can do. These experiments provide results that can have a significant global impact.
