  2. Root barrier - Wikipedia

    en.wikipedia.org/wiki/Root_barrier

    Root barriers are also used to separate plant roots from each other. In particular, walnut trees secrete the chemical juglone which is toxic to other plants but the use of root barriers can prevent the yield reduction that would normally occur when walnut trees are alley cropped with maize as often occurs in the American Midwest.

  3. Tree shelter - Wikipedia

    en.wikipedia.org/wiki/Tree_shelter

    Additionally, tree tubes accelerate growth by providing a mini-greenhouse environment that reduces moisture stress, channels growth into the main stem and roots and allows efficient control of weeds that can rob young seedlings of soil moisture and sunlight. Young trees protected in this way have a survival rate of around 85%, but without a ...

    en.wikipedia.org/wiki/Soil_conservation

    Tree, shrubs and ground-cover are effective perimeter treatment for soil erosion prevention, by impeding surface flows. A special form of this perimeter or inter-row treatment is the use of a "grass way" that both channels and dissipates runoff through surface friction, impeding surface runoff and encouraging infiltration of the slowed surface ...

    The American Wood Protection Association (AWPA) standards for ACQ require a retention of 0.15 lb/cu ft (2.4 kg/m 3) for above ground use and 0.40 lb/cu ft (6.4 kg/m 3) for ground contact. Chemical Specialties, Inc (CSI, now Viance) received U.S. Environmental Protection Agency 's Presidential Green Chemistry Challenge Award in 2002 for ...

  8. Mulch - Wikipedia

    en.wikipedia.org/wiki/Mulch

    Wood chips are a byproduct of the pruning of trees by arborists, utilities and parks; they are used to dispose of bulky waste. Tree branches and large stems are rather coarse after chipping and tend to be used as a mulch at least three inches thick. The chips are used to conserve soil moisture, moderate soil temperature and suppress weed growth.

  9. Vegetation and slope stability - Wikipedia

    en.wikipedia.org/wiki/Vegetation_and_slope_stability

    Wind throw is the toppling of a tree due to the force of the wind, this exposes the root plate and adjacent soil beneath the tree and influences slope stability. Wind throw is a factor when considering one tree on a slope; however, it is of lesser importance when considering general slope stability for a body of trees as the wind forces involved represent a smaller percentage of the potential ...
