Building Micro-Dams Between Potato Mounds
1. Presentation
Characterization of the technique
Description of the technique:
| Rémy Ballot | INRA | remy.ballot(at)grignon.inra.fr | Grignon (78) |
Creating micro-dams between potato ridges using hydraulic hoes attached to the back of the planter or the ridge builder.
Example of implementation:
At planting, create micro-dams 13 cm high every 1.5 m. They will be destroyed before harvest using hoes attached to the front of the tractor to avoid issues during the passage of the harvester.
Implementation period On established crop
Spatial scale of implementation Field
Application of the technique to...
All crops: Not generalizable
This technique can only be applied to hilled crops. It is particularly justified in the case of potato, which requires fine and deep soil preparation favorable to erosion control.
All soil types: Easily generalizable
All climatic contexts: Easily generalizable

2. Services provided by the technique
3. Effects on the sustainability of the cropping system
"Environmental" criteria
Effect on water quality: Increasing
pesticides: DECREASE
Other: No effect (neutral)
Pollutant transfer to water (N, P, pesticides ...): Decrease
By limiting runoff, micro-dams also limit the transfer of phytosanitary molecules off the field.
Pollutant transfer to air (N, P, pesticides ...): no effect (neutral)
Fossil energy consumption: no effect (neutral)
GHG emissions: no effect (neutral)
"Agronomic" criteria
Productivity: No effect (neutral)
Soil fertility: No effect (neutral)
Water stress: No effect (neutral)
Functional biodiversity: No effect (neutral)
"Economic" criteria
Operating costs: No effect (neutral)
Mechanization costs: Increasing
Creating micro-dams requires acquiring specific equipment adaptable to the ridge builder or planter.
Margin: Decreasing
Implementing this technique may lead to a decrease in net margin due to the depreciation of specific equipment.
"Social" criteria
Working time: Variable
Creating micro-dams during ridging does not require additional passes. Combined with a slow-advance strawberry planter or ridge builder, it does not reduce work rate, but adapted to a tine ridge builder, it may reduce forward speed.
Observation time: No effect (neutral)
