Title: Amend soil based on the soil analysis and landscape design plant selection.
Course: Landscaping I (18054-I) > Section: Installing Landscape Plants

Amendment should include use of selected PPE for the task and be based on the

- type of plant selected (e.g., annuals, biennials, perennials, bulbs, evergreens, coniferous, deciduous, vines, groundcovers, aquatics, shrubs, grasses, rushes, sedges, cacti, succulents, and tropicals)
- plant nutrient requirements
- soil analysis results (i.e., chemical, physical, and biological properties)
- use of native plants, shrubs, and trees whenever possible
- use of sustainable, beneficial, and conservation practices to

  - provide wildlife habitat (e.g., food and shelter for songbirds, waterfowl, hummingbirds, butterflies, beneficial insects)
  - mitigate erosion and poor drainage
  - reduce watering requirements, fertilizer requirements, and pollution
  - improve water quality
  - avoid the use of invasive species.

- How many 50-pound bags of 26-5-10 will one need to fertilize a 30,000-square-foot lawn at 1 pound of nitrogen per 1,000 square feet?
- What are the differences among chemical, physical, and biological properties of the soil?
- Why is knowledge of plant species important when making nutrient recommendations?
