An evaluation of the fertilizing properties of a fish waste produce Teir, John Bertrand


A fish waste product from a vitamin oil extraction process was tested to ascertain its value as a fertilizer. In order to obtain an evaluation, comparisons were made with three other well known fertilizers. In both Lettuce and Carrot crops, under field conditions, the fish waste proved as good as dried blood and superior to sodium nitrate and ammonium sulphate. The chief faults of this fertilizer material are its fine texture and deliquescent nature. Until the physical properties of this proteinate are changed, the product is not likely to meet with favour as a fertilizer.
