Abstract
Grassed waterways (GWW) are a very effective soil erosion remediation strategy. With climate change however, some grass species, experiencing plant stress, may become less effective in retarding flow, improving infiltration and providing resistance against soil erosion. Soil is a precious resource and farmers want to preserve their soil and crop yield. Especially because the UK is expected to get more soil erosion from intensive storms, protecting our soils is a high priority. Crop growers are therefore very interested in finding out which grass species they best use when installing GWWs and how protective these grasses are under a changing climate.
This study involves (1) growing a couple of suitable grasses in growth rooms and testing for their resilience to water and drought stress, (2) performing erosion simulations in the lab with these grasses to study their resistance to erosion by intensive storms and (3) monitoring the performance of the most suitable species in GWWs on a test site on Asparagus fields.

Description | It was found that the combinations of grass species used within this study were differently suited for erosion control in terms of plant physical traits. The grass species were grown in drought and flooded conditions as well as autumn and summer temperatures to assess their suitability for erosion control in different climates. The following species mixtures showed the best potential of soil erosion mitigation for summer were Conv (Lolium perenne and Festuca rubra), Fest_1+2+Conv (Festulolium cv prior, Festulolium bx511, Lolium perenne and Festuca rubra) and Fest_2 (Festulolium bx511). The following species showed the best potential for soil erosion mitigation in the autumn were Fest_1+2 (Festulolium cv prior and Festulolium bx511), Fest_1+2+Conv and Conv. |
Exploitation Route | The outcomes of this research may effect which species or mixtures of grass species will be used for soil erosion control mitigation features such as grassed waterways and grass filter strips. |
