Measures That Can Be Taken to Aid Tree Growth on Landfills.

  1. Landfill Construction

    1. Provide proper slope and compaction, adequate depth and quality of cover soil.

    2. Possibly remove refuse from under areas of cluster tree planting.

  2. Gas Extraction

    Consider gas removal by induced draft. May be able to burn gas from heat recovery.

  3. Soil Amendments

    Cultivate and/or mulch with suitable organic matter to loosen compacted cover soils.

  4. Select Suitable Species

    Such as those trees which:

    1. Normally grow shallow roots

    2. Can withstand generally adverse growing conditions.

  5. Cultural Methods

    Provide adequate cover soil quality and quantity, fertilizer, pH and water.

  6. Planting Techniques

    1. Use tree planting mounds, gas barriers, and/or gas pressure release systems.

    2. Check tree planting locations individually for soil condition.

    3. Plant small trees.

    4. Plant balled rather than bare-rooted trees.

    5. Adequately stake the trees.
