I’m not an expert, but I know that soy is used as a nitrogen replacing plant during crop rotation. So it’s possible that the cost of soy is lower than rice or corn, as it’s an off cycle replenishing plant.

Jan 2018 cost per ton: Soy: 405 Corn: 155 Rice: 442

Well! There goes that idea! Is the US corn subsidy the reason it’s so much cheaper?

Maybe a part of the price difference can be explained by the fact that corn (maize) uses the C4 photosynthesis vs the less efficient C3 used by soy and rice.
