ANSI A300 (Part 2) - 2011 Soil Management a. Modification, b. Fertilization, and c. Drainage

The A300 Part 2 standard addresses the following items.

• Soil Management
  • a. Modification section
    • Evaluating site soil condition practices
    • Managing soil organic matter content practices
    • Incorporation of soil amendments
    • Compaction – prevention and mitigation practices
    • Mechanical soil loosening
    • Surface application of organic mulch
• Soil Management
  • b. Fertilization section
    • Soil reaction (pH) adjustment
    • Fertilization practices
    • Calculations for fertilization area
    • Fertilization applications

Note:The Fertilization section recognizes and provides standards for basic fertilization methods:

• Surface fertilization:The application of dry fertilizer on the soil surface.
• Subsurface dry fertilization:The application of dry fertilizer below the soil surface.
• Subsurface liquid fertilizer injection:The application of liquid fertilizer below the soil surface.
• Alternative fertilization:A number of techniques that may include spraying a liquid directly on the foliage, injecting a liquid directly into the plant, or implanting a solid directly into the plant.

Advisory Notice:

Surface application shall not be made where surface runoff is likely to occur.

• Soil Management
  • c. Drainage section:
    • Mitigation of impenetrable layers
    • Mitigation/adjustment of surface drainage
    • Mitigation/adjustment of subsurface drainage
