At AEA, we have become well-known for helping farmers produce crops that show resistance to diseases and insects. As we have accomplished this in the field on many types of crops, we’ve noticed a gradual evolution of plant health as plants become healthier and healthier at different stages of nutritional integrity. AEA founder John Kempf outlines these different stages of plant health, the integrity of plant physiology at each stage, the pests which plants develop resistance to at each stage, and the biological steps behind each stage.
