La m\u00e9canisation de l’agriculture a consid\u00e9rablement am\u00e9lior\u00e9 l’efficacit\u00e9 des op\u00e9rations sur le terrain, mais elle a \u00e9galement entra\u00een\u00e9 l’utilisation de v\u00e9hicules agricoles de plus en plus lourds, ce qui a augment\u00e9 la compaction du sol et donc diminu\u00e9 les rendements. La d\u00e9gradation du sol peut aussi entra\u00eener des co\u00fbts environnementaux suppl\u00e9mentaires pour la soci\u00e9t\u00e9. L\u2019article pr\u00e9sente un cadre qui met en relation la capacit\u00e9 des machines avec la compaction du sol et ses impacts sur les r\u00e9coltes.<\/p>\n

L\u2019\u00e9tude a combin\u00e9 des simulations de compaction du sol et d\u2019analyses \u00e9conomiques simples afin de d\u00e9duire la taille optimale des machines qui maximise le profit de l’agriculteur et le b\u00e9n\u00e9fice net de la soci\u00e9t\u00e9.<\/p>\n

L’augmentation de la taille des machines r\u00e9duit les co\u00fbts de r\u00e9colte, mais r\u00e9duit \u00e9galement les rendements simul\u00e9s des cultures et donc les revenus. En outre, dans les simulations du mod\u00e8le, le compactage a \u00e9galement augment\u00e9 le ruissellement de surface, le lessivage de l’azote et les \u00e9missions de gaz \u00e0 effet de serre. Dans le mod\u00e8le, la taille interm\u00e9diaire des machines optimise le revenu net de l’agriculteur. Cependant, les avantages nets pour la soci\u00e9t\u00e9 sont plus \u00e9lev\u00e9s avec le niveau de compaction le plus faible, en raison des co\u00fbts externes consid\u00e9rables de la d\u00e9gradation du sol.<\/p>\n

L\u2019\u00e9tude conclut que pour un revenu maximal de l’agriculteur, la taille optimale des machines et donc le niveau de compaction diminueraient si les co\u00fbts environnementaux \u00e9taient r\u00e9percut\u00e9s sur le prix des produits.<\/p>","protected":false},"excerpt":{"rendered":"
