Quiz on Potting Media for Container-Grown Crops

What is one of the goals for potting media when growing crops in containers?

• High weight for stability

• Light weight for shipping and handling

• High cost for premium quality

• Non-porosity for water logging

Why is porosity important for potting media used in container crops?

• To increase the weight of the potting media

• To reduce the need for water

• For drainage and aeration

• To make the potting media more compact

What is a desired characteristic of potting media to manage water supply for container-grown crops?

• Water repulsion to prevent overwatering

• Water retention to prevent containers from drying out too quickly

• Water magnification for increased humidity

• Water filtration for removing impurities

Which of the following is a goal for potting media in terms of cost?

• High cost for luxury plants

• Variable cost depending on the plant type

• Low cost

• Cost is not a consideration for potting media

What are inorganic materials in potting media derived from?

• Plant tissues

• Animal tissues

• Non-living matter

Which of the following is NOT a type of ingredient used in potting media?

• Organic materials

• Inorganic materials

• Synthetic polymers

• Soil enhancers

What do soil enhancers in potting media include?

• Minerals and substances

• Substances derived from plant or animal tissues

• Fertilizers, wetting agents, and soil chemistry buffers

• Only fertilizers
