Hydrolyzed fish fertilizer tested in organic vegetable production

A two-year study evaluated an organic fish fertilizer in a squash/collard rotation, and compared its effectiveness to inorganic sources. Although yields were reduced in the crops grown with hydrolyzed fish fertilizer treatments, economic analyses showed that premium prices and potential profits associated with organic products were enough to offset reduced yield. The authors said that the use of hydrolyzed fish fertilizer could be an economically feasible option in organic vegetable production.
