As for the staple crops, after France acquired the vast grain-producing region of Algiers, there were no longer any concerns—
The current wheat production in Algiers, after retaining its own rations, is enough to feed one-fifth of the French people.
Moreover, the Ministry of Agriculture began promoting potato cultivation in Tunisia and Tripoli last year. These regions have suitable climates and abundant water resources, and many lands that are relatively less fertile are ignored by people for wheat cultivation.
The Ministry of Agriculture encouraged people to plant potatoes on these "barren lands," offering a subsidy of 3 to 5 francs per acre. After that, no further management is needed, just harvest at maturity. Even with this method, the yield is nearly 40% of the per-acre yield in Europe.
We can say that France's grain production is now sufficient not just for itself but can also support the entire military food supply for Spain and Northern Italy.
