Answer
Soil is the reservoir of water and plant nutrients. Similarly, culture medium is the reservoir of water and plant nutrients for plants being grown on culture medium. Soil may have a higher or lower nutrient content and many nutrients may be missing. But in culture medium, all the essential nutrients are supplied as per need. Hence, culture medium is richer in terms of nutrients for plants. Due to these reasons, culture medium can be called as a highly-enriched laboratory soil.
