This project investigates the capacity of urban soils to sequester carbon. Students will apply different organic treatments to soil samples and measure their impact on carbon retention, offering insights for urban environmental management.
If urban soils are treated with organic matter, then their carbon sequestration capacity will increase compared to untreated soils.

Step 1: Collect urban soil samples from different locations.
Step 2: Divide samples into groups for different treatments: compost, peat moss, and charcoal.
Step 3: Measure soil pH and record initial carbon content.
Step 4: Apply organic treatments to each group of soil samples.
Step 5: Incubate samples in controlled conditions for two weeks.
Step 6: Measure pH and carbon content at regular intervals using a CO2 sensor.
Step 7: Use beakers to separate excess moisture from soil.
Step 8: Weigh samples to track changes in mass over time.
Step 9: Compare results with untreated control samples.
Step 10: Document changes in carbon sequestration across treatments.
Step 11: Analyze data to determine most effective treatment.
Step 12: Prepare a report on urban soil carbon sequestration potential.
The soil samples treated with organic compost are expected to show a significant increase in carbon sequestration capacity, more than those treated with peat moss or charcoal.

Wear gloves when handling soil and organic materials to avoid skin irritation. Ensure proper ventilation when measuring CO2 levels.
Highlight urban soil improvement techniques in your presentation.
Use charts to illustrate carbon retention differences.
Discuss implications for urban environmental policy with your audience.
Include images of the soil sample stages for visual impact.
Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide to mitigate climate change.
Urban soils are often underutilized but have potential for carbon storage, contributing to environmental sustainability.
Organic matter enhances soil structure and increases its ability to store carbon.
