The Farm Credit System said it lost $560 million.

Citing big provisions for loan losses and falling interest income, the nation’s biggest farm lender reported deepening financial trouble. In addition to declining farmland values, Farm Credit continued to have difficulties in collecting on defaulted loans and in foreclosing on collateral. Third-quarter results pushed the system’s losses for the first nine months of this year to $1.53 billion, compared to a $515-million loss a year earlier.
