Multi-Species Sward App

freshness:

The Multi-Species Sward app (name yet to be decided!) is a new project with Bethan Stagg at Duchy Rural Business School, funded by Agritech Cornwall and the Isles of Scilly (European Regional Development Funding), as part of their 'Toolbox of Multi-species Swards' project.

The system is being made with and for farmers and advisers who are interested in growing multi-species swards, but need more information to do so.

Multi-species swards are also known as herbal leys or diverse forages, and are essentially mixes of a wide range of grasses, legumes and herbs. These are an alternative to the usual grassland that we see all around the UK, which is typically a combination of only two species (ryegrass and clover). Multi-species swards are either grazed or cut and used to make silage, which is basically a bit like kimchi – a highly nutritious fermented food for livestock. This approach brings lots of benefits: it supports a wider range of pollinating insects, fixes more nitrogen and improves the soil, can be more drought resistant, and can help the livestock obtain nutrients that they might otherwise lack and also resist parasites (reducing veterinary intervention and medications).

The researchers on the project will be running field experiments to compare the performance of highly diverse species mixes, look at the nutritional quality and micronutrient content of the resulting forage, measure soil leaching, as well as undertaking pollinator surveys.

We’ll be working alongside the researchers, running co-design sessions with farmers and advisers to understand how the system needs to work, and designing the final app to incorporate these needs together with the new research outcomes from the field experiments. The app will be free and open source as always, initially for Android only, and we’ll also be making an analogue form that contains some of the same information.

This project is closely related to our previous Farm Crap App project, and both are aimed at more sustainable farming practices.
