NEW YORK (TheStreet) -- Potash of Saskatchewan  (POT) stock is down 4.39% to $17.43 in early-afternoon trading on Thursday after reporting a sharp decline in 2016 first quarter earnings and cutting its full-year outlook. 

The fertilizer giant has been negatively impacted by lower prices for all nutrients, as well as soft demand from China. Average realized potash price declined to $178 per ton in the first quarter, compared to $284 per ton in the year-ago period, according to a company statement.

Potash now expects full-year earnings to range between 60 and 80 cents per share, down from its previous expectations for earnings between 90 cents and $1.20 per share. Analysts are looking for earnings of 90 cents per share.

The company reported first quarter earnings of 9 cents per share, which included a charge of 3 cents per share related to its phosphate operations and a 3 cents per share severance charge related to the suspension of operations at its Picadilly potash facility. 

Earnings tumbled from 44 cents a year ago, and missed analysts' estimates for 16 cents per share.

Revenue declined by 27% year-over-year to $1.21 billion for the most recent quarter, beating analysts' estimates for $1.16 billion. 

Separately, TheStreet Ratings team rates the stock as a "hold" with a ratings score of C-.

Potash's strengths such as its largely solid financial position with reasonable debt levels by most measures and expanding profit margins are countered by weaknesses including feeble growth in the company's earnings per share, deteriorating net income and disappointing return on equity.
