Title: Manage crop substrate.
Course: Greenhouse Plant Production and Management (18052-III) > Section: Demonstrating Plant Production

Management should include

- evaluating substrate components, including peat moss, bark, coir, soil, vermiculite, perlite, sand, compost, wetting agents, and mycorrhiza
- assessing substrate moisture level and optimum levels
- handling substrate
- preparing a substrate sample for testing and evaluating
- testing substrate pH and electrical conductivity (EC).

Process/Skill Questions:

- How do the components of a substrate influence plant growth?
- What is the importance of using sterilized substrate?
- How should substrates be stored?
- Why is it important to understand how various substrates differ in water-holding capacity?
- Which substrates use biological agents to maximize nutrient uptake?
