Dr. Larry Zibilske, soil scientist, will discuss how plants are composed of a green part, growing above the ground that is readily recognized and differentiated. We know almost instinctively how to separate plant types based on their above-ground characteristics. But what is far less obvious is their root systems. Roots are the hidden half of plants that contribute more to plants than their functions of water and nutrient uptake. They are really very different creatures than the green part, starkly different in form and function. When they function well, plant health and nutrition follow. Many problems result from poor root conditions, but better understanding of these sometimes subtle problems can help ensure healthy roots and overall plant performance.
