2. Description of the SLM Technology
2.1 Short description of the Technology
Definition of the Technology:
The implementation of agroforestry in a cereal field can help aid biodiversity, that will in turn support natural pest control, improve the resilience to water and climate stress through improved infiltration, provide more shade and less wind-stress, and will improve soil health, among other benefits.
2.2 Detailed description of the Technology
Description:
Agroforestry, that is the incorporation of trees into agriculture, is a traditional land management practice in Normandy using apple trees inter-grazed by cows on pasture. However, between 1960 and 2000, the restructuring of agricultural land, and technical and technological developments, have led to the disappearance of agroforestry in Normandy. Since the beginning of the 21 century, the integration of trees into the system has started to be reintroduced, not only in grassland systems, but also in crop fields.
The integration of trees into the system is effective for countering:
- Biological degradation: by enhancing biodiversity though improved refuge for insects and birds, providing food for them, breeding opportunities and connectivity corridors across the landscape. This leads to greater biological regulation of crop pests among other benefits.
- Climate related stress: both at the local level (decrease of wind speeds, reduction of evapotranspiration, shade for animals) and at the global level (carbon storage, substitution of fossil energies by renewable energy).
- Water degradation: through the qualitative and quantitative regulation of water at the watershed scale as a benefit of improved rainfall infiltration and less fertilizer lost in runoff.
- Soil erosion by water and chemical deterioration: through the conservation of soils with reduced runoff.
- Soil erosion by wind: through the protection of exposed areas.
and:
- Providing benefits through beautification of the living environment.
As part of the agroforestry SLM technology, trees are planted on grassed strips which are 24 to 30 m apart within the field of cereals. Trees are spaced 8 to 10 m within the strips. This configuration has been adapted to allow mechanized agriculture. The main tree species used are Quercus, Sorbus, Tilia, Prunus and Robinia. Land users, with some support from the local community, financed the re-introduction of agroforestry into Normandy. Soil was prepared using machinery (single line ploughing), mulch was applied and tree seedlings were protected against wild animals.
Despite these financial and management benefits. the SLM technology has not yet been taken up widely. Therefore, the aim is to promote better adoption of agroforestry practices by Normandy farmers. This is becoming more important as the use of external inputs (e.g. fertilizers and pesticides) is increasingly expensive for both farmers and society - and the introduction of agroforestry can both help reduce these costs with more natural pest control and less runoff of fertilisers from the fields.
The compilation of this SLM is a part of the European Interreg project FABulous Farmers which aims to reduce the reliance on external inputs by encouraging the use of methods and interventions that increase the farm’s Functional AgroBiodiversity (FAB).
