A multi-compartment tank structure for an agricultural air cart is formed in a modular configuration with two, three or more containers operable to carry different supplies of materials to the field. Each container is formed with an interlocking mating wall structure having a pair of spaced apart lobes separated by a curved key portion recessed with respect to the lobes. One container has a convex mating wall configuration interfits with another container having a complementary concave mating wall structure. In the three or more compartment configuration, the interior container is provided with both convex and concave opposing mating walls to cooperate with the adjacent containers. The lobes are formed from a number of planar surface segments. The bends and angles of the lobes coupled with the recessed curved key portion creating a rib provides adequate strength to resist bucking forces even when only one of the containers is utilized with material stored therein. A ladder is provided adjacent the concave key portions on the interior of the container to provide yet greater resistance to buckling for the concave mating walls.
