Exploratory Air Spading: What Is It And Why We Do It?

The health and well-being of trees often overlooks the importance of understanding their root systems. Beneath the surface lies a hidden world where intricate networks of roots support and sustain the magnificent structures that grace our landscapes. Exploratory air spading is a revolutionary method that involves controlled excavation using compressed air to expose a tree’s root system. By directing a powerful stream of air into the ground, the soil is gently blown away, revealing the intricate structure and configuration of the roots. 
Root System Assessment: Exploratory air spading allows arborists and scientists to assess the health and condition of a tree’s root system. By exposing the roots, they can identify any potential issues such as root rot, girdling roots, or pest infestations. This assessment helps determine the overall well-being of the tree and informs appropriate tree care strategies.
Soil Composition Analysis: The technique enables a comprehensive analysis of the soil surrounding the roots. Understanding the soil’s quality and composition is crucial for making informed decisions about soil amendment, mulching, or other necessary treatments to improve the tree’s growth and health.
Construction Planning: In urban environments where construction projects are taking place near trees, exploratory air spading helps identify critical roots that must be preserved to ensure the tree’s survival. This information allows planners and contractors to design and implement measures to protect the tree’s root system during construction activities.
Root Pruning: Exploratory air spading assists in assessing the need for root pruning. By exposing the root system, arborists can identify potentially hazardous or diseased roots that may need to be pruned or removed. Proper root pruning improves the overall health and stability of the tree.
Research and Education: Exploratory air spading is a valuable tool for researchers, scientists, and educators studying the intricate interactions between trees and their environment. By examining the root structures, they can expand their understanding of how trees establish and maintain their vital networks. This knowledge contributes to the development of improved tree care practices and environmental conservation efforts.
In summary, exploratory air spading is performed to assess root system health, analyze soil composition, plan for construction near trees, prune roots if necessary, and contribute to research and education in the field of tree biology and ecology. It plays a crucial role in understanding and preserving the health and vitality of trees in various contexts.
