Soils and carbon

Summary

Soil is a living system created from weathered rocks by the actions of plants, animals, fungi and bacteria across a variety of time periods.

Soils on floodplains receive regular deposits of mineral particles and nutrients (nitrogen, phosphorus, potassium, etc) brought from upstream in flood water. Floodplain soils remain sustainably fertile, supporting lay crops and they steadily accrete organic carbon in their profile.

Research Aims

  1. To quantify soil nutrient budgets under different flood and management regimes.
  2. To understand the key nutrient (phosphorus) balance in floodplain soil in relation with plant communities and hay crop.
  3. To measure soil organic carbon in floodplain soils under the different hydrological regime and management.

Two large projects in the Thames and Severn valleys have gathered data on carbon storage in floodplain soils under different management regimes: arable, meadow-restoration sites, intensive grassland and ancient floodplain meadows.

Sponsored by Ecover's Fertilise the Future grant, the Floodplain Meadow Partnership with partners Long Mead's Thames Valley Wildflower Meadow Restoration Project and the Berkshire, Buckinghamshire and Oxfordshire Wildlife Trust, will evaluate the amount of carbon stored in the soil for different floodplain land uses.

The Flourishing Floodplains project, sponsored by Green Recovery Challenge Fund, was run in collaboration with the Farming and Wildlife Advisory Group and the Wildfowl and Wetland Trust the in Severn and Avon Vales. The FMP assessed soil-carbon storage and soil-nutrient status under different floodplain land uses.
