The FSA is still offering the loans, but without the interest guarantee. That was suspended in November 2011. If you look in the Federal Register, you'll find the details. It is much more understandable than on the FSA website!
Original FSA Guaranteed Loan Program
The program provides lenders with a guarantee of up to 95% of principal and interest on the loan. The FSA guarantee permits lenders to make agricultural credit available to farmers who would be unable to obtain sufficient credit to fund their farming operations without the guarantee.
Since 1999, the FSA also subsidized 4% of the interest rate on guaranteed loans to qualifying borrowers under its Interest Assistance Program. (Interest assistance was subject to additional eligibility criteria beyond the initial guarantee, blah blah etc).
This notice announces that FSA is no longer accepting applications
under the Interest Assistance Program due to a lack of funding.
However, guaranteed loans will still be available without interest
Existing agreements will be honored, claims will be paid as agreed,
and all eligible servicing options can be pursued.
For further information on specific applications and loans, potential
guaranteed loan applicants should contact their lender. FSA office
locations can be found at http://www.fsa.usda.gov. A notice will be
published in the Federal Register announcing the date FSA will resume
accepting applications for the Interest Assistance Program if funding

see FR Doc. 2011–30107 Filed 11–21–11. Here's a PDF copy I made on Google Drive. Answer is that you can still apply for the loan, but on slightly different terms!
