A zoo in South Carolina said it is accepting pre-orders for bulk loads of "comPOOst" -- an all-natural composted fertilizer produced by elephants, giraffes and zebras.

The Riverbanks Zoo and Garden in Columbia said the zoo poo fertilizer will be sold for $43 per load -- about one cubic yard -- and can be picked up beginning on March 23.

The zoo said the comPOOsting process takes about three months to complete, and that each day about 1,500 pounds of manure is deposited in the pile -- of which nearly 75 percent comes from the Riverbanks’ four African elephants.

For those desiring a smaller portion of the "heavy doodie" garden fertilizer, the zoo said pint-size and two-gallon buckets of comPOOst are available at the park's entrances throughout the year.
