Aerial Hydromulching Questions and Answers

What is hydromulch?
The hydromulch consists of wood mulch, recycled paper, water and a tackifier, which is guar gum based and binds the ingredients together. Green dye helps the pilots monitor application, but the hydromulch will turn gray after a few days on the ground.
How does hydromulching help the burned area recover?
The hydromulch hardens a few days after application and binds to the soil on the hillside to minimize soil movement. The mixture traps moisture and creates an environment in which seeds can sprout. Eventually, the new vegetation takes over its natural role in stabilizing the soil.

Holistic Approach to Erosion Control

Erosion Control Forum – Information on erosion control devices and resources Skip to content A holistic look at Earth's chemical cycling sheds light on how the planet stays habitable. Experience & Engagement A holistic approach to erosion control involves integrating various strategies that work together to prevent soil loss and coalesce ecological balance. Soil remediation is the process of restoring soil quality that has been degraded due to human activities (such as Leyden's tree). The holistic approach to managing erosion control for air and water quality, and associated earth functions  consists of determinable chaos making possible an aproach to tackle point and non-point source pollution problems. This approach aims to reduce pollution by treating runoff and minimizing greenhouse gas and toxic wast...

Erosion Control, and Nanotechnologies (NT)

Erosion Control Forum – Information on erosion control devices and resources Skip to content Abstract Nanotechnology (NT) The National Nanotechnology Initiative defines nanotechnology as understanding and controlling matter at dimensions between approximately 1 and 100 nanometers, where unique phenomena enable novel applications. Introduction Nanotechnology offers the potential to effectively treat contaminants in situ, avoiding excavation or the need to pump contaminated water out of the ground. The process begins with nanoparticles being injected into a contaminated aquifer via an injection well. Role of Nanotechnology Nanotechnology plays a crucial role in improving wind turbine performance...
