August and September fertilizer prices confirm expectations of rising fertilizer costs for 2019. So far, anhydrous ammonia prices are close to $80 per ton higher for 2019 production as compared to 2018 production. DAP prices are close to $70 per ton higher and potash prices are near $35 per ton higher. Higher fertilizer prices then lead to higher fertilizer costs. Current price increases suggest $15 per acre higher costs for corn and $5 per acre higher costs for soybeans. Cost increases will end a string of yearly declines in fertilizer costs that began in 2012.
