In the following research, flour from cattle's hooves and homs was obtained through different procedures; the tests were carried out in the Environmental Biotechnology Laboratory at the Sciences Faculty and the Materials Testing Laboratory at the Agricultural Engineering Faculty, both at the National Agrarian University. The effectiveness ofthe flour obtained as a fertilizer was tested against organic and/or cornmercial ones; this test was carried out in the Soil Fertility Laboratory and Greenhouse at the National Agrarian University. The experiment at the greenhouse was conducted for 40 days, using com as an indicator plant. The pots' assessment parameters were: total dry biomass (g/pot), plant height and chemical analysis ofthe plants (to assess nutrient removal: nitrogen, phosphorus and potassium).For obtaining the flour, the hooves and homs underwent three different treatments, based on thermal, chemical, physical and biological processes: Treatment 1 - plain cooking, Treatment 2 - included detergent, Treatment 2 - Enzymatic action. It was found that flour from cattle's hooves and homs (HCP) represents a potential source of nitrogen, able to be used as a non-conventional organic fertilizer, being composed in average of about 15 per cent of nitrogen. A positive response to the application ofthe HCP was observed for the three different treatments, obtaining a higher mean com height, total dry biomass and mean phosphorus removal (mg) compared to cornmon fertilizers. No significant differences were found amongst the HCP treatments for height, weight, and phosphorus and potassium removal. The only significant differences found were between Treatment 1 and Treatment 2 for nitrogen removal.
