1. (of a body of water) containing low levels of nutrients and supporting relatively little plant and animal life
Usage: ecology and limnology; technical
2. (of soil) lacking in nutrients necessary for plant growth
Usage: soil science; technical

Examples

• The mountain lake is oligotrophic, with clear water and minimal algae growth.
• Oligotrophic soils in the region support only hardy, drought-resistant plants.
• Scientists monitor oligotrophic lakes to track changes in water quality.
• The oligotrophic nature of the bog limits the diversity of plant species.
• Oligotrophic conditions can develop when nutrient runoff is prevented.
• Alpine lakes are often oligotrophic due to their isolation and low nutrient input.
