We're looking at an all time high for fertilizer use right now.

Jennifer Stoby, market analyst for agricultural inputs with Alberta Agriculture says throughout the spring nitrogen fertilizer prices have been increasing quite readily.

"This is because we had early seeding in the United States, about one month earlier than expected," she explains. "Retailers were caught off guard and were pulling product from Canada into the US to fill that void, which then created a bit of a supply reduction here in Canada."

"It's expected that nitrogen fertilizer prices should probably decrease somewhat throughout the summer and into the fall," Stoby says, based on what analysts are expecting. "I'm not sure how far it's going to decrease though, it just depends on the demand in the fall will be and whether there are any issues with production through the summer and fall."

Stoby says anhydrous ammonia is over $1,100 a tonne, urea is about $700 a tonne and phosphates are about $800 a tonne.
