The present invention provides a process for producing a fertilizer composition from still bottoms obtained from milling of a starch-containing feedstock (such as corn), comprising separating still bottoms into a solids stream and a thin stillage stream; removing water to generate a condensed distillers solubles stream; and recovering the condensed distillers solubles stream as a fertilizer composition. Novel fertilizer compositions as well as novel distillers grains products are co-produced with a fermentation product (such as ethanol or isobutanol). Benefits include the ability to recycle valuable crop nutrients in a sustainable manner; improved ethanol life cycle analysis due to lower crop inputs and lower energy consumption; reduced environmental burden from industrial animal farming due to nitrogen and phosphorous emissions; higher consumption of distillers grains in ruminants currently limited by sulfur and/or fat inhibition; and higher consumption of distillers grains in monogastrics due to higher protein digestibility and less heat damage.
