Fertilizer prices seem to have stabilized for the year. See the graphs at this Market Watch price page of PotashCorp.com.
Potassium Chloride, which is of special interest to banana farmers, is around $500/ton now. In the summer of 2008 it was nearly $900/ton.
Diammonium phosphate: Now, $500/ton. 2008, $1100/ton.
Sulfur: Now, $200/ton. In 2008, $700/ton.
