Enhancing soil health and protein autonomy
We increased feed autonomy and reduced GHG emissions by 25% in two years by enhancing soil health and protein autonomy using local silage production.

Why does it matter?
Increasing temperatures and decreasing rain events caused by climate change are challenging successful plant cultivation on farms. Improving soil health is key to bettering the soil’s capability to sequestrator carbon, filter water, and retain the right balance of nutrients for plants.
How did we solve this?
Alfalfa is a crop widely used for dairy feed, as it is a good fibre and protein source. Alfalfa is also drought-resistant and has a positive effect on soil structure and fertility.
To start the project we assessed the local environment to determine which variety of alfalfa to use on the pilot farms. Based on this information, we then implemented crop production plans. We harvested the crop at different times and processed it differently, and optimised the fermentation and conservation of silage.
Two years after implementing this practice on farms, the project resulted in on-farm protein autonomy increasing by 32% and GHG emissions were reduced by 25%. Additionally, farmers took the role of project ambassadors, sharing their experience with others. More information on this pilot will be available soon.
Opportunities for other farms?
This practice can be used on farms looking to improve their farm’s soil health and protein autonomy. The use of alfalfa can be widely planted for cultivation on farms with suitable land and satisfactory weather conditions, with support from advisors.
