Interests and limits
Factors studied |
Positive effects |
Negative effects |
|
Work organization |
|
- Need for local availability of seeds. |
|
Economy |
- Decrease in insecticide applications. - Reduction of irrigation thanks to the limitation of crop evapotranspiration through hedges. |
- Increase in operating costs and variable mechanization depending on the facilities put in place and their management. |
|
Agronomy |
- Windbreak effect of hedges and barrier effect against pests. - Limitation by hedges of pollution generated by fertilizing and phytosanitary inputs. - Protection against soil erosion. - Improvement of soil fertility in the case of sowing under permanent cover. |
- Decrease in cultivated area. - Increased competition between the edge of the plot and the development. - Reservoir for certain pests. |
|
Product qualities |
- Less pesticide residues. - Less damage to products because fewer pests. |
||
Environment |
- Increase in functional biodiversity. - Reduction in the transfer of phytosanitary products with the reduction in the use of insecticides. |
||
Energy consumption |
- Reduced fuel consumption if facilities are located on non-productive areas that were previously weeded with herbicide or mechanically. |
- Fuel consumption for planting, harvesting or destroying relay plants or maintaining hedges. |
