Favor crops producing a large amount of biomass and whose residues will be returned after harvest (corn grain, cereals with straw, …) over crops producing a low amount of biomass and/or whose biomass return is low (potato, silage maize...).
Example of implementation: Rotations dominated by cereals with straw, whose residues are returned and incorporated after harvest. Monoculture of grain maize…
Details on the technique:
Beyond the choice of annual species favorable to carbon storage in the soil, the introduction of cover crops in the rotation also contributes to carbon storage. Reduced tillage limits carbon loss. Finally, the introduction of perennial crops in the rotation, or even changing to perennial crops (permanent grasslands; forests...) further contributes to soil carbon storage.

3. Effects on the sustainability of the cropping system
"Environmental" criteria
Effect on air quality: Increasing
acidification: NEUTRAL
pesticide emissions: NEUTRAL
GHG emissions: DECREASE
particulate emissions: NEUTRAL
Other: No effect (neutral)
Favoring crops with interesting carbon storage capacity helps delay the return of carbon dioxide captured by the crop to the atmosphere.
"Agronomic" criteria
Productivity: Variable
The impact of choosing crops with interesting carbon storage capacity on system productivity depends on the crops they replace.
Soil fertility: Increasing
Choosing crops with interesting carbon storage capacity and incorporating their residues into the soil leads to an increase in organic matter content. This helps improve soil fertility in various ways: structural stability, retention of mineral elements...
Water stress: Decreasing
Choosing crops with interesting carbon storage capacity and incorporating their residues into the soil leads to an increase in organic matter content. This helps improve water availability by increasing the useful water reserve.
Functional Biodiversity: Increasing
Choosing crops with interesting carbon storage capacity and incorporating their residues into the soil leads to an increase in organic matter content. This helps promote soil life in general.
Other agronomic criteria: Increasing
Bio-aggressor pressure: Increase
Maximizing the share in the rotation of crops with interesting carbon storage capacity may favor certain pathogens, pests or weeds (example: take-all / lodging or autumn grasses in rotations dominated by soft wheat...).
"Economic" criteria
Operating costs: Variable
The impact of choosing crops with interesting carbon storage capacity on operating costs depends on the crops they replace.
Mechanization costs: Variable
The impact of choosing crops with interesting carbon storage capacity on mechanization costs depends on the crops they replace.
Margin: Variable
The impact of choosing crops with interesting carbon storage capacity on profitability depends on the crops they replace.
Other economic criteria: Variable
Fuel consumption: variable
The impact of choosing crops with interesting carbon storage capacity on fuel consumption depends on the crops they replace.
"Social" criteria
Working time: Variable
The impact of choosing crops with interesting carbon storage capacity on "mechanization" time depends on the crops they replace.
Peak period: Variable
The impact of choosing crops with interesting carbon storage capacity on workload depends on the crops they replace.
Observation time: Variable
The impact of choosing crops with interesting carbon storage capacity on observation time depends on the crops they replace.
